Somewhere between a phone camera and a mailbox, a stack of paper documents needs to become one PDF. It's one of the most common small conversions there is — signing a form and photographing it, scanning receipts for an expense report, or turning a photographed whiteboard into something you can actually file away.
Combining images into one PDF
- Open the JPG to PDF tool and drop in your images — JPG or PNG, one file or a whole batch at once.
- Drag the thumbnails into the order you want them to appear in the final document.
- Choose a page size: fit each image to a standard A4 page, or keep every page sized to match its original image.
- Click Convert to PDF. Every image becomes one page, combined into a single downloadable file.
A4 fit vs. original size — which to pick
Fitting to A4 is the right choice almost anytime the PDF is going to be printed or shared as a standard document — it gives every page the same consistent dimensions regardless of what size or aspect ratio the source photos happened to be. Keeping the original size matters more when the image itself is the point — a screenshot, a diagram, or a photo where cropping or letterboxing would lose information you actually need. If you're not sure, A4 is the safer default for anything you'd call a "document" rather than an image.
Getting a cleaner scan from a phone photo
A photo taken straight-on, in even light, without a shadow from the phone itself, converts far more legibly than one shot at an angle. If a page comes out slightly crooked or upside down after converting, there's no need to re-photograph it — rotate the page directly in the finished PDF instead.
What happens to the images
Each image is embedded into the PDF at its original resolution rather than being recompressed, so text in a scanned document stays as legible as the source photo allowed. If the resulting file ends up too large to email, running it through the Compress PDF tool afterward is the fastest way to bring it down to size. As with every tool here, the images never leave your device — the whole conversion happens locally in your browser.
