Turn images into a PDF

Photographs of a document, screenshots of a thread, scans that arrived as separate files — turning a pile of images into one PDF is one of the most common things anybody needs and one of the most annoying to do without handing the pictures to a website. Here the conversion happens in the page you are reading.

How it works

  1. 01Choose the images, or drop them in.
  2. 02Pick a page size — or let each page match its own image.
  3. 03The PDF opens straight into the editor.
  4. 04Reorder, rotate or compress it, then export.

They arrive in the order you expect

Images are sorted by name, and numerically rather than alphabetically — so IMG_2, IMG_10 and IMG_100 land in that order instead of 10, 100, 2. That single detail is the difference between a usable result and reordering forty pages by hand.

Nothing is cropped to fit

Choosing A4 or Letter scales each image to fit inside the page and centres it, adding whitespace where the shapes do not match. It never crops to fill, because losing the edge of a photographed document is exactly the failure that makes a scan useless. If you would rather have no whitespace at all, "fit each image" gives every page the size of its own picture.

It becomes an ordinary PDF immediately

Once converted, the document opens in the same editor as everything else — so you can reorder the pages, rotate the ones that came out sideways, crop the scanner border, compress the result and protect it, all in the same session before exporting once.

Photographs are large

A modern phone photo is several megabytes, and twenty of them make a PDF of sixty. Once the document is open, Compress will usually take most of that back — a photographed page rarely needs the resolution the camera captured.

Questions

What formats can I use?
PNG and JPEG. Those are the two image formats a PDF can carry directly; anything else would have to be re-encoded, and silently converting your file to something else is not a decision a tool should make for you. HEIC from an iPhone needs converting first.
Can I mix PNG and JPEG in one document?
Yes, freely. Each image is embedded in its own format.
Does it re-compress my photos?
No. Images are embedded exactly as they are, so nothing is lost in the conversion. If you want them smaller, that is a deliberate second step with the Compress tool.
Are my photos uploaded?
No. The PDF is assembled by your own browser — photographs of documents are precisely the thing people should not be posting to a converter site.
