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.
Converter
Pick the converter that matches your files
They all produce the same PDF. The separate pages exist because the formats fail in different ways, and each page tells you what to watch for with that one.
HEIC to PDF
iPhone photos, without emailing them to yourself first.
JPG to PDF
The plain one. Any number of JPGs, one PDF.
PNG to PDF
Transparency flattened onto white, not black.
WebP to PDF
The format everything you save off the web is in now.
Merge images into one PDF
Reorder the pages before you export.
Screenshot to PDF
Phone screenshots that stay readable when printed.
DNG to PDF
Pulls the full-size preview out of the raw file.
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.
What this tool will not do
| You want | Use instead |

| Searchable text from a photo of a document | An OCR tool. This makes a picture of the page, not text you can select. |
| Straightening and cropping a photographed page | The iPhone Notes scanner, covered in the scanning guide. |
| Adding a photo into a PDF you already have | Add an image to a PDF. |
| Signing or filling in a PDF | Preview on a Mac, or the Files app on iPhone. |

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.
