Images to PDF — without uploading

Most photo-to-PDF jobs are documents rather than pictures: a passport photographed for a visa application, receipts assembled for an expense claim, a signed page snapped with a phone, ID for a rental application. These are precisely the images you should not be uploading to a free converter, and they are the ones people upload most often, because the need is urgent and the tool is one search away.

Here the images are embedded into the PDF by code running in your browser. There is no backend on this site to receive them, and a Content-Security-Policy blocks third-party requests. Load the page, go offline, and you can still build the document.

Photos taken on an iPhone are HEIC (or HEIF) rather than JPEG, which is why they so often refuse to open on Windows and get rejected by upload forms. They work here directly — no conversion step first, and no emailing the photo to yourself to get a JPEG out the other side.

HEIC files are decoded on your device by a small WebAssembly decoder that only downloads when you actually drop a HEIC file, so people converting ordinary JPEGs never pay for it. As with everything else, the photo is not sent anywhere to be converted. If you want the JPEGs themselves rather than a PDF, the image converter handles HEIC to JPG on your device, and there is a guide on converting HEIC to JPG.

Drag the images into the order you want before building — for a multi-page document scanned with a phone, order is the whole point. Then choose how pages are sized:

• Fit each page to its image — every page takes the exact dimensions of the picture on it. No borders, nothing cropped. Best when the result is meant to be viewed on screen.
• A4 or US Letter — standard pages with the image fitted inside margins, switching to landscape automatically when an image is wider than it is tall. Choose this for anything that will be printed or submitted to an office, since consistent paper size is usually a requirement.

Photographs of documents produce large PDFs, since a phone camera image is several megabytes before it becomes a page. If the result needs to clear an email limit, Compress PDF downsamples the embedded images on your device; adding page numbers is worth it for anything being submitted formally.
