How it works
- Add your photos. JPG, PNG or WebP, up to 20 at a time. They stay on your device.
- Pick paper and size. A4 or US Letter, portrait or landscape, with common sizes or your own.
- Review and download. You see each sheet as it will print and download a single PDF with no watermark.
How many photos fit on a sheet
With 5 mm margins and a 2 mm gap between photos, using the better paper orientation, this is how many photos fit per sheet at actual size:
| Photo size | A4 | US Letter |
|---|---|---|
| 10 × 15 cm | 2 | 2 |
| 9 × 13 cm | 4 | 4 |
| 13 × 18 cm | 2 | 2 |
| 5 × 5 cm | 15 | 15 |
| 4 × 6 in (101.6 × 152.4 mm) | 2 | 2 |
A US Letter sheet is 8.5 × 11 in. Two 4 × 6 in photos fit; a third does not. If you want a set number per sheet instead of a fixed size, use “Photos per sheet” and the tool works out the resulting size.
To get the right size
- In the print dialog choose actual size or 100%; never “fit to page”.
- Use the same paper you chose here (Letter or A4).
- Print the check sheet first and measure the 5 cm square.
- Most home printers can’t print to the edge: leave a margin.
Privacy: your photos stay with you
Photos are read and turned into a PDF inside your browser. There are no accounts and no file uploads, and this version uses no analytics or ads. Nothing is saved: if you reload the page your photos disappear and you will need to add them again.
Frequently asked questions
Is a 4 × 6 in photo the same as 10 × 15 cm?
Not exactly. 4 × 6 in is 101.6 × 152.4 mm, slightly larger than 100 × 150 mm. PaperFit Studio treats them as different sizes.
Will my photos be cropped?
Only if you choose “Fill the frame”. With “Whole photo” they are fully visible, and bands may appear if the photo’s proportions differ from the frame’s.
What resolution do I need?
As a guide, 300 ppi gives a sharp print and below 150 ppi it may look soft. The tool warns you photo by photo, but it cannot invent resolution the image does not have.
Can I use iPhone HEIC photos?
For now JPG, PNG and WebP are supported. Convert HEIC to JPG on your device before adding them.
