JPG to PDF Converter

Turn photos and screenshots into one tidy PDF, one image per page.

Every tool runs entirely in your browser. Your files are never uploaded to a server.

Converting JPG to PDF places each image on its own page in a single document, without recompressing the photo. Choose a page that fits the image exactly, or A4 and Letter for printing. It runs in your browser.

How to use JPG to PDF Converter

  1. Add your images. Drag in JPGs, PNGs or WebPs. They become pages in the order they are listed.
  2. Choose the page. Fit to image keeps every pixel and adds no white space. A4 or Letter is what you want if it is going to a printer.
  3. Build and save. One PDF comes back with one image per page, ready to send or print.

About converting JPG to PDF

A PDF made from photographs is a container, not a conversion. Each image is embedded whole and drawn onto a page, which is why the resulting file is usually a little larger than the sum of the pictures rather than smaller — you are adding a document structure around them, not compressing them. This matters most for JPGs, because JPEG data can be placed into a PDF exactly as it stands. No pixel is decoded, re-encoded or degraded, and a twenty-page PDF of photographs is bit-for-bit as good as the twenty files that went in. PNG is embedded losslessly too. WebP is the odd one out: the PDF specification has no native WebP image type, so it has to be decoded and re-encoded as JPEG on the way in, which is the one path here that costs a little quality. Page sizing is the choice people get wrong most often. A page fitted to the image has the same proportions as the photograph and no margin, which is ideal on screen and awkward on paper, because printers scale unfamiliar page sizes unpredictably. A fixed A4 or Letter sheet is predictable on paper and wasteful on screen, since a phone photo leaves bands of white on two sides unless the page turns to match it. Decide by where the file is going: a printer wants a real sheet size, an email attachment does not.

Frequently asked questions

Are my photos recompressed?
JPGs are not. The original JPEG data is embedded in the PDF exactly as it is, so there is no second round of lossy compression and no quality drop. PNGs are embedded losslessly. WebP has no native place in PDF, so it is converted to a high-quality JPEG first.
Should I pick "fit to image" or A4?
Fit to image if the PDF is for viewing or sending: every pixel is preserved and there is no white border. A4 or Letter if it is going to a printer, because a page sized to a phone photo will otherwise print at whatever scale the printer guesses.
What happens to a landscape photo on a portrait page?
With the orientation toggle on, the sheet turns to match the photo, so it fills the page. With it off, the photo is shrunk to fit the width and sits centred with white space above and below.
What order do the pages come out in?
The order the images are listed in, which is the order you added them. Add them in the sequence you want, or drop them one group at a time.
Is anything uploaded?
No. Your browser reads the images, embeds them and writes the PDF locally. Nothing is transmitted at any stage.
