PicToPDF

Free · no upload · no account

Photo to PDF, without handing your photos to anyone

Drop in JPG, PNG, HEIC, WebP or DNG files and get one PDF back, one photo per page, in the order you choose. The conversion happens inside this tab. Nothing is uploaded, nothing is stored, and there is no watermark on the way out.

  • Runs in the browser. No server sees your files.
  • JPGs are embedded untouched, so nothing is recompressed twice.
  • Reorder pages, set A4 or Letter, add margins.
  • Works with iPhone HEIC files on Windows and Android too.

How the conversion actually works

A PDF is a container. When you convert a photo, one of two things happens, and the difference decides whether the file gets worse.

If the photo is already a JPG, this tool copies the compressed bytes straight into the PDF as a DCTDecode stream. No decoding, no re-encoding, no generation loss. The PDF ends up roughly the size of the original photo plus a couple of kilobytes of structure.

If the photo is a PNG, WebP, HEIC, GIF or DNG, it has to be decoded and written back out as JPEG, because that is what a PDF viewer can display without a plugin. That is one compression pass. Leave Quality on High and you will not see it. Set it to Smallest and you will, on anything with text or hard edges.

Page size, and why Fit is usually right

Fit the photo makes each page exactly the shape of the image. No white bars, no cropping, and the PDF looks like a photo album. This is the right answer when the PDF is going to be read on a screen.

A4 and US Letter put each photo on a standard sheet, scaled to fit and centred, with the page rotated to landscape automatically when the photo is wider than it is tall. Use these when someone is going to print the file, or when a form says it wants an A4 PDF.

Margins only matter for the printed case. Most home printers refuse to print into the outer few millimetres of a sheet, so a photo that runs edge to edge gets clipped. Small or Normal fixes that.

Questions people actually ask

Do my photos get uploaded anywhere? +
No. The conversion runs in this browser tab using the file APIs your browser already has. There is no server call, which is also why it still works if you go offline after the page loads.
Why is there a daily limit? +
Because a free unlimited converter is a free file server, and this site exists to introduce the iPhone app. On an iPhone you get one PDF a day here; on Android and desktop you get five. The app has no cap.
Does converting to PDF make the photo worse? +
Not if you leave quality on Original. A JPG is embedded into the PDF byte for byte, so it is the same image data in a different container. Anything that is not already a JPG has to be encoded once, and the High setting is visually lossless for photos.
Can I put several photos into one PDF? +
Yes. Add as many as you want, drag the order around with the arrows, and you get one PDF with one photo per page. That is what merge images into one PDF does.
What is the largest file I can convert? +
There is no hard cap, but everything happens in your device's memory. A phone will manage 30 to 50 photos comfortably. A laptop will chew through several hundred. If a very large batch stalls, split it in two.
Is there a watermark? +
No watermark, no account, no email wall. The only limit is the daily count.

The app has no daily limit

The web tool is capped so the page does not turn into a free file server. PicToPDF on iPhone converts straight from the camera roll, keeps the originals untouched, and works on a plane with no signal.
