About Images to PDF

Photographs, screenshots or scanned sheets into one PDF, in the order you choose. Everything the browser can decode is accepted — JPEG, PNG, WebP, GIF, BMP, HEIC from a phone, and SVG — and all of it is redrawn on a canvas before it goes in.

A PDF can only hold two kinds of picture: JPEG and PNG. That is not a limitation of this tool, it is the file format, and it is why everything is re-encoded. The choice between the two is made per image: anything with transparency becomes PNG, because JPEG has no alpha channel, and everything else becomes JPEG, because a photograph stored as PNG is roughly three times the size for no visible difference. That single decision is the usual reason an image-to-PDF converter produces a 90MB file from a handful of holiday photos.

Leaving the page size as "fit each page to its picture" makes a document with no margins and no white space — right for a comic, a set of screenshots, or anything that will be read on screen. Choosing A4 or Letter centres each picture on a real sheet instead, which is what you want if it is going to be printed or filed.

Where it helps

  • Takes everything the browser can decode, including HEIC from an iPhone and SVG, without a separate conversion step first.
  • Chooses JPEG or PNG per image, which is what keeps the output a sensible size.
  • Sorts by file name with numeric awareness, so page-2 comes before page-10.
  • Either one page per picture at its own size, or every picture centred on a real sheet.
  • The pictures never leave the browser — no upload, no queue, no copy on somebody's server.

Limits

  • Everything is rasterised. An SVG goes in as a picture of itself at the size it was decoded, not as vector artwork that stays sharp when zoomed.
  • JPEG re-encoding at 90% quality is lossy; a photograph that has already been through several conversions will soften slightly.
  • There is no OCR here, so the result is pictures of words rather than searchable text — run it through the OCR tool afterwards if it needs to be searchable.
  • 40MB of pictures in one run is the ceiling, since all of it is decoded in a browser tab.
  • A multi-page TIFF is read as its first page only; browsers do not decode the rest.

Frequently asked questions

Why is my PDF so much bigger than the photos were?

Usually because the pictures had transparency and went in as PNG, which stores every pixel exactly. Flattening them onto a background first — or exporting them as JPEG before you start — makes a dramatic difference on photographic content.

Can I make the text in the scans searchable?

Not here — this makes a picture of each page. Run the result through the OCR tool, which reads the words and lays an invisible text layer over the image.

Does it keep the original resolution?

Yes. Each picture is embedded at its decoded pixel dimensions; with the page size set to "fit", the page is exactly that size in points, so nothing is resampled.

Why is my HEIC slower than the others?

HEIC is decoded by a WebAssembly library because browsers cannot open it natively. The first one pays for loading the decoder; the rest are quick.
