Your photos stay sharp
A JPG that is already the right way up goes into the PDF byte for byte, so there is no loss of quality and the PDF is about the same size as your photos. Phone photos are often stored sideways with a note saying which way to turn them. Those are turned upright first, then saved at high quality, so they do not appear sideways in the PDF. PNG images go in losslessly, and WebP images are converted to high-quality JPG.
Page size, orientation and margins
- A4 (210 × 297 mm) is the standard in Pakistan, India, the UK and most of the world, and the safest choice for forms and printing.
- US Letter (8.5 × 11 in) is used in the United States and Canada.
- Same as photo makes each page exactly the size of its photo, which suits albums and screen viewing.
With orientation set to Automatic, landscape photos get landscape pages and portrait photos get portrait pages, so nothing is shrunk more than it needs to be. Photos are scaled to fit inside the margin and centred, never stretched or cropped. A small margin of about 6 mm stops printers from cutting off edges.
Tips for document scans
- Photograph pages in daylight, flat on a dark surface, from straight above.
- Crop each photo to the edge of the page before you add it.
- If the PDF is too large for an upload limit, run the photos through the Image Compressor at 1600 px first.
- Name your photos in page order, such as 01, 02 and 03, so they arrive already sorted when you add them together.
Private and quick
Everything happens in your browser. The PDF library loads only when you press Convert, and the PDF is built in a background worker, so even 50 photos do not freeze the page. Your photos are never uploaded to a server.
