How to use it
- Choose crop or fit, and portrait or landscape if offered.
- Drop your photo.
- Download it and print at 100% (no "fit to page").
About 4 × 6 inches
It is the standard photo print size in the US and many other countries (10 × 15 cm). At 300 DPI that is 1200 × 1800 pixels.
The tool converts inches to pixels using the DPI you choose, then writes that DPI into the file. Print software reads it and prints at the right physical size.
Questions
Why does my print come out cropped at the shop?
Phone photos are usually 3:4 or 9:16, while a 4 × 6 print is 2:3. Resize here first with "Fit without cropping" and the whole photo will print, with thin borders instead of lost edges.
What DPI should I use?
300 DPI is the usual standard for photo prints and gives sharp results. Some online forms ask for 200 DPI; change it under Settings and the pixel size updates to match.
Is my photo uploaded to a server?
No. The resizing runs inside your browser with JavaScript, so the image never leaves your device. Once the page has loaded, resizing keeps working even if you go offline.
