Page size

Margin

Photos are turned the right way up automatically using the orientation tag your phone writes, and the page is turned to match each picture, so a landscape shot gets a landscape page instead of two thick white bars.

Converting a JPG to a PDF wraps the picture in a page rather than changing it. A PDF stores JPEG images in their original form, so a good converter copies the compressed data straight in and nothing is re-encoded and no quality is lost. The two things that separate a clean result from a bad one are whether the tool reads the EXIF Orientation tag, which decides if your phone photos are upright or on their side, and whether it lets you choose the page size, which decides how the file prints. Add your images above, pick US Letter or A4, and the PDF is built with one image per page in the order you added them.

Why photos come out sideways, and what we did about it

This is the single most common complaint about image to PDF converters, and the cause is not mysterious. It is one tag that most tools never read.

What your phone actually records

A phone held upright does not rotate the pixels it captures. The sensor writes its native landscape frame and the camera adds EXIF tag 274, Orientation, telling any viewer how far to turn the picture before showing it. Photos, Preview, Finder and every web browser obey that tag, which is why the photo looks perfectly correct everywhere you normally see it.

A converter that copies the raw pixels into a page never sees the instruction. The picture is placed exactly as the sensor recorded it, which is to say lying on its side, and the page is built landscape to match. Nothing is corrupted. The rotation was simply never applied.

What we measured

We built a test photo the way a phone builds one: an 800 by 600 sensor frame with Orientation set to 6, the value meaning turn a quarter turn clockwise, with the left half red and the right half blue. Handed to the PDF library untouched, it went onto the page as 800 by 600 with the red half still on the left, so no rotation at all. Read the tag first and it becomes 600 by 800 with red on top.

We then compared our rotated output against what an image viewer displays for the same file, pixel by pixel. Zero pixels differed. What you get in the PDF is what you see in Photos.

EXIF Orientation value What it means Typical source Handled here
1 Already the right way up Screenshots, scans, edited exports Yes, and the JPEG is copied in untouched
6 Turn a quarter turn clockwise The common portrait phone photo Yes
8 Turn a quarter turn counter clockwise Portrait, phone held the other way Yes
3 Turn upside down Phone held inverted Yes
2, 4, 5, 7 Mirrored, with or without a turn Front cameras and some scanners Yes, mirrored as well as turned

The mirrored values are rare, and plenty of tools that handle the ordinary rotations quietly skip them. They are handled here because a mirrored page is worse than a sideways one: it looks almost right until somebody tries to read the text in it.

Does converting to PDF reduce the image quality?

It does not have to, and here it usually does not. The reason is a detail of the PDF format that most converter pages never mention.

A PDF does not have its own picture format. For photographs it uses JPEG directly, through a filter called DCTDecode, which means the compressed data a camera produces can be placed inside a PDF and left alone. No decoding, no re-encoding, no second generation of compression artefacts. The picture in the document is the picture from the camera.

We checked that this is really what happens rather than assuming it. After building a PDF from a test JPEG we pulled the image stream back out of the finished file and compared it against the original: identical, byte for byte, all 8,230 of them. There is no quality setting on this page because on that path there is nothing to set.

There is one honest exception. If a photo has to be rotated to honour its orientation tag, the pixels must be decoded, turned and written again, and that re-encode costs one generation of JPEG quality. It is written back at a high quality setting and the difference is not visible in normal use, but it is a real change and you should know which files it applies to.

What you upload What happens to it Quality cost
JPG, already upright Copied into the PDF exactly as it is None at all
JPG that needs rotating Turned, then written again as JPEG One re-encode, high quality
PNG Embedded as it is, transparency kept None at all
GIF and BMP Converted to JPEG first One encode, high quality

Because nothing is shrunk on the way in, the PDF is roughly the combined size of the images you added. That is the right default for a document you are keeping or printing. If you need it smaller for email, compress the finished PDF afterwards, where you can trade quality for size deliberately instead of having it decided for you.

US Letter, A4, or a page shaped like the picture

Most online converters default to A4 without asking. If you are in the United States and the document is going to a printer, that is the wrong default, and the mismatch is big enough to matter.

Page size Dimensions Choose it when
US Letter (default) 8.5 by 11 in, 215.9 by 279.4 mm The document will be printed or filed in the US, or sent to a US office
A4 210 by 297 mm, 8.27 by 11.7 in The recipient is outside the US, or a form or portal asks for A4
Fit the image Whatever shape the picture is The PDF is for reading on screen and white borders are wasted space

A4 is about 6 millimetres narrower and 18 millimetres taller than Letter. Send an A4 PDF to a Letter printer and the driver either scales the whole page down, leaving an uneven white border and slightly smaller text, or prints at full size and loses the bottom strip. Neither is fatal, and both look like somebody rushed the job. Picking the right size at the point of conversion costs one click.

In Letter and A4 mode the page is also turned to match each picture, so a landscape photo lands on a landscape page. Without that, a wide photo on a portrait page is scaled down to fit the narrow dimension and floats in the middle with deep white bands above and below it, which is the other tell of a converter that was not paying attention.

Which image formats work, and which do not

Listing formats a tool cannot really read is how people end up with an error message halfway through a job. This is the actual list, including the gaps.

Format Supported Notes
JPG, JPEG Yes Embedded with no re-encoding unless it needs rotating
PNG Yes Transparency is kept. The usual format for screenshots
GIF Yes An animation contributes its first frame, since a page cannot move
BMP Yes Converted to JPEG on the way in
HEIC, HEIF No The iPhone default. See below for the ten second fix on the phone
TIFF, WebP No Re-save as JPG or PNG first. Any image editor will do it

About HEIC, because it is the one people hit

HEIC is what an iPhone saves by default, and it is genuinely not supported here. HEIC pictures are compressed with HEVC, and the image libraries on this server are built with an AV1 decoder and no HEVC decoder, so a real iPhone HEIC cannot be opened at all. We would rather tell you that on this page than accept the file and fail after the upload.

Apple documents the fix and it takes about ten seconds. On the iPhone open Settings, then Camera, then Formats, and choose Most Compatible. Every photo taken from then on is an ordinary JPEG. Apple notes that High Efficiency saves storage at the same visual quality, so it is worth switching back afterwards if space is tight. For photos you have already taken, opening one on a Mac or in any editor and exporting it as JPG works.

Your camera and location data travels into the PDF

This one catches people out, and it is a direct consequence of the lossless path being a good thing. When a JPEG is copied into a PDF without being re-encoded, everything in that file goes with it, including the EXIF block: camera make and model, the date and time, the settings, and on a phone photo the GPS coordinates of where you were standing. The PDF viewer does not display any of it, so the document looks clean, but the data is sitting inside the file for anyone who opens it with the right tool.

We measured it rather than warning about it vaguely. A test photo was tagged with a camera make, a model name and a set of GPS coordinates, converted to a PDF, and the image was then pulled back out of the finished document. The make, the model and the coordinates were all still there and all still readable.

There is a quirk worth knowing. A photo that had to be rotated is decoded and written again, and that process drops the EXIF block, so rotated photos come out stripped while upright ones do not. That is an accident of how the rotation works, not a privacy feature, and it is exactly the kind of inconsistency you should not rely on.

If the document is going outside your organisation, to a client, a court, a marketplace listing or a public site, treat the metadata as a separate step. Strip the metadata from the finished PDF and you can see what was in there before you decide.

How to convert JPG to PDF

1

Add the pictures

Drag in up to 30 images, or pick them from a folder. JPG, PNG, GIF and BMP are accepted, up to 20MB each. The order you add them is the order of the pages.

2

Choose the page

US Letter is the default because most people here print on Letter. Switch to A4 for anywhere else, or fit the page to the picture for a document meant to be read on screen.

3

Convert

Each picture becomes one page. Photos are turned upright from their orientation tag and the page is turned to match, so nothing lands sideways and nothing floats in a band of white.

4

Download

The PDF comes back immediately. Your uploads are already deleted at that point, and the result is deleted the moment you download it.

The free built in ways, and where each one stops

Windows, macOS and iOS can all make a PDF out of a picture without any extra software, and for one image that is often the quickest route. It is worth knowing where each of them runs out, because that is the point where a converter earns its place.

Where The built in method Where it stops
Windows 10 and 11 Select the images in File Explorer, right click, choose Print, and pick Microsoft Print to PDF as the printer It is a print dialog, so you are choosing a photo layout rather than a page. Margins and scaling follow the print preset, and Microsoft has acknowledged updates in which the Print to PDF printer disappeared from the printer list entirely
macOS Select the files in Finder, control click, open Quick Actions and choose Create PDF. Apple documents this in the macOS user guide Quick and genuinely good. It gives you no control over the page size, so the result is sized from the images rather than to Letter or A4
iPhone and iPad Open the picture in the Preview app, tap the filename, choose Export and pick PDF Aimed at one file at a time. Turning twelve photographed pages into one document means repeating it twelve times and then merging the results
This page Add up to 30 images at once, choose Letter, A4 or fit, and set the margin The files are uploaded to a server, so for material under a confidentiality duty the built in methods, which never leave your machine, remain the safer choice. HEIC is not supported

The honest summary is that for a single picture you probably do not need this page at all. The reason people come looking is the batch: a stack of receipts, a contract photographed page by page, or a set of scans that has to arrive as one attachment.

What people are actually converting

Expense claims

Photographed receipts turned into one PDF per trip or per month, because most expense systems take a single document and not thirty separate images.

Signed paperwork

A contract signed on paper, photographed page by page, sent back as one file with the pages in the right order and every page upright.

Notes and handouts

Photographs of a whiteboard, a textbook chapter or a printed handout, collected into a single document that is easy to file and easy to share.

Insurance and property

Damage photographs, inspection shots and condition reports, gathered with a page each so the PDF can be printed and filed as evidence.

Applications and filings

Portals and offices that ask for supporting documents almost always want PDF, often at a specific page size, and often as one file rather than several.

Listings and catalogs

Product photographs assembled into a document for a supplier, a wholesale buyer or a print shop, in a fixed order.

Questions people ask about converting images to PDF

How do I convert JPG to PDF?

Add the images above, choose a page size, and download the PDF. Each image becomes one page, in the order you added them. Nothing is installed and no account is needed. A JPG that does not need rotating is copied into the PDF exactly as it is, so the picture inside the file is the same data your camera wrote.

Can I combine multiple JPG files into one PDF?

Yes. Add up to 30 images at once and they come back as a single PDF with one image per page, in the order you added them. This is the usual reason people convert images at all: a set of receipts, a signed contract photographed page by page, or scans that need to travel as one attachment rather than twenty.

How do I convert JPG to PDF without losing quality?

Use a converter that embeds the JPEG rather than re-encoding it. A PDF stores JPEG images natively, so the original compressed data can be copied straight in with no quality loss at all. This tool does that whenever the photo does not need rotating: the JPEG inside the finished PDF is byte for byte identical to the file you uploaded.

Why do my photos come out sideways when I convert them to PDF?

Because the converter ignored the EXIF Orientation tag. A phone held upright still records the sensor frame in landscape and sets a tag telling viewers to turn it. Photos and your browser obey that tag, so the picture looks correct there, but a converter that copies the raw pixels puts it on its side. This tool reads the tag and rotates before building the page.

Why can't I convert JPG to PDF?

Usually the file is not really a JPG. Phones commonly save HEIC, screenshots are often PNG, and a file renamed to .jpg keeps its original format inside. Check the real format first. If it is HEIC, set the iPhone to Settings then Camera then Formats then Most Compatible so it writes JPEG, or re-save the picture as JPG or PNG on a computer.

How do I convert a PNG to PDF in A4 size?

Pick A4 in the page size options before converting. A4 is 210 by 297 millimetres and US Letter is 215.9 by 279.4, so they are not interchangeable: an A4 page printed on Letter paper is scaled down or clipped. This tool defaults to Letter because the audience prints on Letter, and A4 is one click away.

How do I convert JPG to PDF below 100KB?

Convert first, then compress the finished PDF, because the image data is what the size is made of. Converting alone does not shrink anything: the JPEG goes in at its original size on purpose, so quality is preserved. If you need a specific target size, run the resulting PDF through a compressor and pick a stronger setting.

How do I turn a photo into a PDF on my iPhone?

Apple builds it in, but only one picture at a time and only for what is already on the phone. For several photos in one document, or to control the page size and margins, a converter is faster than repeating the built in export and then merging the results. This page works in Safari on the phone, though HEIC photos need converting to JPEG first.

Does converting a photo to a PDF remove the camera and location data?

Not by itself, and this surprises people. When a JPEG is embedded without re-encoding, its EXIF block travels with it, camera make and model and GPS coordinates included, hidden inside the PDF. We measured this: coordinates written into a test photo were still readable inside the finished PDF. Strip the metadata afterwards if the file is leaving your organisation.

Are HEIC photos from an iPhone supported?

No, and we would rather say so than fail halfway through. HEIC uses the HEVC codec, and the image libraries on this server are built without an HEVC decoder, so a genuine iPhone HEIC cannot be read at all. The fix takes ten seconds on the phone: Settings, then Camera, then Formats, then Most Compatible makes the camera write ordinary JPEG.
