Photos and scans into one PDF, without uploading them
Turning a stack of phone photos into a single PDF is one of the most common reasons people reach for an online converter — and those photos are usually receipts, ID documents, signed forms or medical paperwork. Every mainstream converter uploads them to a server first. This one uses pdf-lib inside your browser, so the images are read from your disk and the PDF is written back to it. Nothing is transmitted.
Match the image, or fit to a page
Match each image makes every page exactly the size of the photo on it. Nothing is scaled, nothing is letterboxed, and no quality is lost — this is usually what you want for scans. A4 and Letter instead fit each image onto a standard page with a small margin, keeping the aspect ratio, which is what you want if the PDF is going to be printed or filed alongside other documents.
JPG, PNG and WebP
JPEG and PNG are embedded directly, so the original compressed data is carried into the PDF untouched. WebP is not a format the PDF spec supports, so those images are decoded by your browser and re-encoded as PNG first — lossless from the already-decoded pixels, though the resulting file is larger than the WebP was. If size matters more than fidelity, convert to JPG first with the WebP to JPG tool.
