What this does
It puts pictures into a PDF, one picture to a page, in the order you choose. A receipt for an expense claim, both sides of an ID card, a few pages of handwritten work photographed on a phone: they come out as one document, the right way up, ready to attach to a form that only takes PDFs.
How to use it
- Choose the pictures — JPG, PNG or WebP, several at once if you like.
- Put them in page order with Up and Down.
- Choose a page size and a margin.
- Press Convert to PDF, then download the file.
What happens to each format
JPG goes into the PDF exactly as it is, byte for byte. PDF stores JPEG natively, so nothing is re-encoded: no quality is lost and the file does not grow.
PNG is stored without loss, and anything see-through stays see-through. A PDF cannot hold a PNG file as such, so the pixels are compressed again the way PDF does it, which makes a photo saved as PNG noticeably bigger. If size matters, turn it into a JPG first with the Image Converter.
WebP cannot go into a PDF at all, so it is changed. An opaque one — almost always a photo — becomes a JPEG at quality 92, which looks the same and keeps the PDF small. A see-through one is stored like a PNG, so its transparency survives.
A picture with no color in it, such as a scan of a printed page, is stored as gray only: a third of the data color would need.
A worked example
A phone held upright takes a 4032 × 3024 photo and stores it on its side, with a note saying which way up it goes. On Letter with no margin, it gets a portrait page of 612 × 792 points. The photo is drawn 594 × 792 points, as tall as the page, with 9 points of white on each side.
A 1920 × 1080 screenshot on "Same as picture" gets a page of 1440 × 810 points: the size it shows at on a screen, at 96 pixels to the inch.
How pictures are placed
Letter is 612 × 792 points and A4 is 595.28 × 841.89, where a point is 1/72 of an inch. A page is turned landscape when its picture is wider than it is tall. The picture is scaled by
s = min((W − 2m) ÷ w, (H − 2m) ÷ h)
where W × H is the page, m the margin (none, or 36 points) and w × h the picture as it is meant to be seen. That makes it as large as the page allows, whole and centered: nothing is ever cut off.
On "Same as picture" each pixel is three quarters of a point, plus the margin. A page is never larger than 14,400 points (200 inches), the largest PDF readers promise to open; a bigger picture is scaled down to fit.
What it does not do
It does not turn, crop or edit a picture — use the Image Rotator or the Image Resizer first. It does not make pictures smaller: the Image Compressor does. And it does not add pictures to a PDF you already have; make a PDF of them here, then join the two with Merge PDF.
Nothing is uploaded
Your browser reads the pictures, builds the PDF and saves it. Nothing is sent anywhere, and the test suite for this page records the requests the tool makes while pictures are processed and fails if one of them could carry one.
Questions
How do I convert a JPG to PDF?
Choose the picture, pick a page size — Letter, A4 or the picture’s own size — and press Convert to PDF. Download the file. Your browser does the work; the picture is never uploaded.
Can I put several pictures into one PDF?
Yes. Choose them all at once, or a few at a time, and put them in order with Up and Down. Each picture becomes one page, in the order of the list, and they download together as images.pdf.
Will a photo from my phone come out sideways?
No. A phone stores a portrait photo as landscape pixels plus a note saying which way up it goes. A PDF reader ignores that note, so this page reads it and turns the photo on the page, the way your phone shows it.
Why is the PDF of my PNG bigger than the PNG?
A PDF cannot hold a PNG file as it is, so the pixels are stored again with the same lossless compression PDF uses, which is less clever than PNG’s own. For a screenshot the difference is small; for a photo saved as PNG it can be large. Convert the photo to JPG first if size matters.
Does it make my pictures smaller?
No. A JPEG goes into the PDF byte for byte, exactly as it is, so the PDF is about the size of the pictures in it. To make the PDF smaller, make the pictures smaller first with the Image Compressor.
Can I add pictures to a PDF I already have?
Not directly. Make a PDF of the pictures here, then put it together with the one you have using Merge PDF, in whichever order you need.
Are my pictures uploaded?
No. Your browser reads the pictures, builds the PDF and saves it on your device. The test suite for this page fails if any request the tool makes while pictures are processed could carry one.
