JPG to PDF, each photo as the camera saved it

Photos into one PDF, in the order you set

Drop one photo or a whole set of them on the convert page, drag them into the order they belong, and convert: each photo becomes a page of one PDF. Choose the paper, A4 or US Letter, or let each page take its photo's own size; turn the pages to suit each photo, or all one way; and keep a white margin round the picture, or none. A photo is made as large as its page allows and keeps its proportions, so it is never stretched or squeezed to fill the paper.

Convert JPG to PDF now — it opens the tool, with nothing to install.

Not compressed again

A JPG is already compressed, and compressing it again would lose a little more of the picture. So it is not: the compressed picture the camera or the scanner saved becomes the page's picture, exactly as it is in the file, and the finished PDF is checked for it before it is offered. Nothing is resampled, sharpened or recoloured. What the camera noted beside the picture, such as where the photo was taken and the camera's serial number, is left out of the PDF. The rare JPG coded in a way a PDF cannot carry is decoded and stored with every pixel kept instead, and the record says which photos that happened to; one coded in a way this tool cannot read at all is refused rather than guessed at.

Upright, as the phone meant

A phone held on its side stores the photo sideways, with a note of which way is up. That note is followed: the page shows the photo upright, while the image inside it is still the camera's own data, set on the page at a turn rather than drawn again. A photo stored mirrored is put the right way round in the same way.

Other kinds of picture

TIFF, WebP and AVIF pictures go into a PDF the same way, as pages in your order, but none of them can be carried as it is, so each is saved again, which changes its bytes. A TIFF keeps every pixel unless its colours have to be converted or reduced, and one of several pages gives a page for each; a WebP or AVIF photo is stored as a JPEG, unless the WebP was saved without loss, when its pixels are kept too. A PNG has its own page, PNG to PDF, and so do an iPhone's photos, HEIC to PDF.

What it turns away

A JPG of more than 100 million pixels is refused before it is opened, and you are told its size: the service opens no PDF that holds a larger picture. A picture that has to be decoded on its way in takes more memory than one that goes in as it is, so its line can be lower. For one in colour, it is 57.5 million pixels for a JPG of the rare kind above, a TIFF or an AVIF photo, and 33.5 million for a WebP. Each is measured from the file before it is decoded, and the message names the line beside the picture's size.

Photos of identity documents — passports, identity cards and driving licences — are refused. Every PDF made here is looked at the way an upload is, and one taken for an identity document is deleted, with everything made from it, as the terms say.

How much at once

One conversion takes up to 50 files, 32 MB of them in all, and each file up to the size your plan uploads. For more files, convert them in batches and join the PDFs with Merge PDF. The PDF it makes holds no more pages than your plan allows in one document.

The record

The PDF says how it was made, in the record it carries and in your account's trail. For each file it names the kind, the fingerprint, and whether its own picture data went in or, for the rare photo that needed it, every pixel of it was kept, and whether it was turned upright. The files you send are kept only until the conversion has answered; the PDF is kept with your documents like any other, and deleted after 90 days, or whenever you erase it. What a download costs is on the pricing page.
