JPG, PNG and WebP. You can also paste images from the clipboard. Set the page order with the arrows in the list below.
Page settings
One image per page, in list order. Fit to image sizes each page from the image itself (pixels converted at 96 dots per inch), so pages in one PDF can differ in size when the images do.

How it works
Your browser does the work
When you add an image, an open-source library (pdf-lib, MIT licensed, stored on this site) loads and builds the PDF on your device. JPG and PNG files are placed in the PDF exactly as they are. WebP files are decoded by your browser and stored as PNG, because PDF has no WebP format. There is no server involved at any step.
Guide
Getting a good result
- Forms and portals: use A4 or Letter with a medium margin, so the printed pages keep a clean border and nothing is cut at the edge.
- Photos to share: use Fit to image. The page matches each photo, so there are no white bands on screen.
- Big files: a PDF built from full-size phone photos stays large, because the photos are stored as they are. Shrink them first with the Image Compressor if a portal sets a size limit.
- Order matters: page 1 is the first image in the list. Use the arrows to fix the order before you build.
Questions
Are my images uploaded anywhere?
No. The PDF is built in your browser, on your device. There is no server receiving your images, which you can verify by loading this page, going offline, and building a PDF anyway.
Which image types can I use?
JPG, PNG and WebP. JPG and PNG are placed in the PDF as they are. WebP cannot sit inside a PDF directly, so your browser converts it to PNG first, with no loss of quality.
What page size should I pick?
Pick Fit to image when the PDF is for viewing or sharing on screen: each page matches its image, with no white border. Pick A4 or Letter when the PDF will be printed, and add a margin so nothing sits at the paper edge.
Does this change the quality of my images?
JPG and PNG images are embedded at their original size and are not recompressed, so they keep their quality. On A4 and Letter pages an image is scaled to fit the page, which changes its printed size, not the stored picture.
