Image to PDF

About making a PDF from images

Most of the reasons for doing this are administrative: a form wants one PDF rather than four photos, a landlord wants the ID and the utility bill in a single file, a claim wants the receipts together. All of those documents are exactly the kind you should not be uploading to a stranger's server, which is why this runs in your browser and makes no request to anyone while it works.

Each image becomes one page, in the order shown, which you can rearrange before you build. The image is scaled to fit inside the page and centred, never stretched, so a photo keeps its proportions. Fit the image exactly makes the page the same shape as the photo with no white space at all, sized for printing at 150 dots per inch, which is the right choice when the image itself is the document.

JPEG and PNG are placed into the PDF untouched, at their original resolution, so a PDF built from twelve phone photographs weighs about what the twelve photographs weigh: running them through the image compressor first is what keeps the result emailable. WebP, AVIF and GIF are converted to JPEG first, because PDF itself has no way to carry them; if a converted image had transparency, the see-through parts become white rather than black, which is what people expect from a printed page.

How to turn images into a PDF

1. Drop your images on the box, click to choose them, or paste a screenshot straight in.
2. Put them in page order by dragging a row by its handle. Each thumbnail shows its pixel size. With a keyboard, focus a handle and use the arrow keys.
3. Choose the page size. A4 for anything going to an office, Fit the image exactly for no white space.
4. Pick a margin. None is right for a full bleed photo, small for a document that may be printed.
5. Press Make the PDF. It downloads immediately and nothing is kept here.
