Convert JPG to PDF 2026 — Free Online

Put JPG photos into a PDF, one image per page. Choose the page size, how much margin to leave, and how hard to compress — everything runs in this tab, so the photos are never uploaded.

A JPG is compressed twice unless you are careful

A JPG arrives already compressed. Embedding it in a PDF re-encodes it at whatever quality you set here, and JPEG compression is not idempotent — running it again on an image that has already been through it adds artefacts to artefacts, most visibly around text and hard edges.

The quality slider is therefore worth a moment's thought rather than being left wherever it sits. At 92% the second pass is invisible for a photograph. Below about 70% you start to see it, and on a photo of a document — a receipt, a whiteboard, a page of notes — you see it much sooner, because those are exactly the sharp edges JPEG struggles with.

If the source photos are already small, there is nothing to gain from compressing further. The PDF will be roughly the size of the images inside it either way.

  • 92% — the second pass stays invisible on a photograph
  • Below 70% — artefacts appear, sooner on photos of text
  • Small source photos: leave the quality high, there is nothing to save

Page size and what happens to the shape

Each image is scaled to fit inside the page you chose, keeping its proportions. It is never stretched. A landscape photo on a portrait A4 page therefore sits as a band across the middle with white above and below, which is correct but not always what people expect.

Switching the orientation to landscape fixes that for a set of landscape photos. For a mixed set there is no single right answer, and the margin control is the useful lever — a smaller margin gives every image more of the page whatever its shape.

A4 is 210 by 297 millimetres, Letter is 216 by 279. Letter is wider and shorter, which suits landscape photographs slightly better and matters if the PDF will be printed in North America.

What a PDF of photos is good for

Sending several images as one attachment rather than a dozen, which mail clients handle far better and recipients lose track of far less. It is also the format most upload forms accept when they will not take images.

The order of the pages is the order of the list, and images can be moved before converting. Nothing is uploaded, so a passport photo or a signed document stays on your machine.

Frequently Asked Questions

Does converting JPG to PDF reduce quality?

It can. The image is re-encoded at the quality you choose, and JPEG compression applied a second time adds artefacts to artefacts. At 92% that is invisible on a photograph; below 70% it is not, especially on photos of text.

Why is there white space around my photo?

Images are scaled to fit the page without being stretched, so a landscape photo on a portrait page leaves bands above and below. Switch the orientation, or reduce the margin to give the image more room.

Should I use A4 or Letter?

A4 (210×297mm) if the PDF will be printed outside North America, Letter (216×279mm) inside it. Letter is a little wider and shorter, which suits landscape photographs marginally better.

Can I put more than one photo on a page?

No — each image becomes its own page. That keeps every photo as large as the page allows, which is usually the point of making a PDF of them.

Are my photos uploaded?

No. The PDF is assembled in this browser tab and the images never leave your device.
