How to convert photos to PDF for free
PDF is the format people expect when you send paperwork: it keeps page order, prints predictably and opens everywhere. Converting document photos to PDF well involves more than changing the file extension — the pages should also come out straight, evenly lit and consistently sized.
Why not just embed the photo?
A raw photo dropped into a PDF still looks like a photo: tilted page, gray background, shadow across one corner. A proper conversion first crops to the page boundary and applies perspective correction, so every page in the PDF looks like it came from a real scanner. That is the difference recipients notice.
Multi-page PDFs from separate photos
In Scandut, scan each photo one after another — each scanned page lands in a tray, where you can review thumbnails and remove any bad page. When you are done, one click merges everything into a single PDF, with each page sized to match its own aspect ratio. Ten receipts, a fifteen-page contract, a chapter of notes: same flow.
Keeping the file size sensible
For text documents, Document or B&W mode produces smaller, sharper files than full color. If the PDF is destined for email, JPG-based pages at moderate quality are usually a tenth the size of PNG with no visible difference for text.
And since the conversion happens locally in your browser, there is no upload limit, no queue and no server keeping a copy of your paperwork.
