Why convert images to PDF?
A PDF keeps several pictures together in a fixed order, opens on every device and prints exactly as it looks on screen. That is why universities, banks, employers and government portals usually ask for one PDF document instead of a handful of separate photos. Typical cases are scanned passports and diplomas, signed contracts photographed with a phone, receipts for an expense report and homework pages.
Choosing the page size
- A4 (210 × 297 mm) — the standard paper size in Europe, Asia and most of the world. Choose it for documents that will be printed or sent to an official body.
- US Letter (8.5 × 11 in) — the standard in the USA and Canada.
- Same as image — every page takes the exact proportions of its picture, with no white borders. Best for screenshots, slides and photo albums.
With Auto orientation, wide photos are placed on landscape pages and tall photos on portrait pages, so nothing is squeezed.
Tips for clear document scans
- Photograph the page from directly above, in daylight, without flash glare.
- Fill the frame with the document and keep the edges parallel to the screen.
- If the final PDF is too large to upload, shrink it with compress PDF, or reduce the photos first with reduce image size in KB.
Phone photos are rotated correctly automatically, and iPhone HEIC pictures are supported without any extra steps.
