Convert images to a PDF

Combine receipts, scans, screenshots, or photographs of a signed form into one PDF without uploading them. Each image becomes a page, in the order shown in the file list, and the list can be rearranged by dragging a card or by moving it with the keyboard before you build the document.

Nothing is recompressed on the way in. A JPEG is embedded with its original bytes intact, so a 125 KB photograph adds roughly 125 KB to the PDF and looks exactly as it did before. The practical consequence is that thirty phone photos make a PDF around the size of thirty phone photos. When the file has to clear an email limit, resize or compress the images first, then assemble them here.

Each page takes the pixel dimensions of its image, and PDF measures pages in points at seventy-two to the inch. A 960 by 1440 screenshot therefore produces a page about 13 by 20 inches, and a full-resolution camera photo produces something far larger still. Readers and printers scale a page to fit the paper, so it prints, but a mixed set of images yields a document of mixed page sizes rather than a tidy stack of A4. Resizing the images to matching dimensions beforehand is what makes the pages consistent.

The declared file type chooses the decoder, so an image saved as PNG but renamed with a .jpg extension is rejected with an error instead of being embedded as something it is not. HEIC from an iPhone and WebP from the web are not accepted here on purpose: converting them first is a decision about format and quality that belongs in the image tools, where you can see the result.

The output has no text layer. A page built from a photograph of a document is a picture of that document, not searchable text, so run the result through OCR if the words need to be findable. Every image stays on your device throughout, which matters for the passports, payslips, and medical letters that people most often need to turn into a single PDF.
