Phones have replaced scanners for most people. You photograph your mark sheet, your Aadhaar or passport, a signed form or a stack of receipts, and then a website or an office asks for one PDF instead of ten JPG files. JPG to PDF turns those photos into a single, tidy PDF, one photo per page, in the order you choose.
Add your photos by choosing them from your gallery or files, dropping them on the page, or pasting them. Each photo appears as a card. Drag the cards into the right order, or use Sort A to Z when the file names already follow the order, such as IMG_2041, IMG_2042. Turn a card with the rotate button if a photo is sideways, and remove one you added by mistake. Ctrl + Z undoes a move.
Then choose the page. A4 is the standard paper size in most of the world and is right for nearly every form; US Letter is used in the United States and Canada; Same as the photo makes every page exactly the size of its picture, with no white border. Orientation can stay on Automatic, which uses portrait pages for tall photos and landscape pages for wide ones, or you can force one. A small margin looks like a printed page; choose None to fill the page edge to edge.
Photos stay sharp. JPG images are placed in the PDF as they are, without being compressed again, so the PDF looks exactly like your photos. The direction your camera recorded is respected, so a photo taken with the phone held sideways is not suddenly lying on its side. Everything happens in your browser: your photos are never uploaded, which matters for ID cards and personal documents.
This tool takes JPG photos, which is what most cameras and phones save. For PNG screenshots, WEBP images or iPhone HEIC photos, use Image to PDF. If the finished PDF is too big for an upload form, continue to Compress PDF or the exact-KB compressor right from the result screen, without choosing the file again.
