How do I resize an image to 4×6 print size (10×15 cm) online?
Upload your photo above, keep the pre-selected 10 × 15 cm (4×6 print) preset or swap to 15 × 10 cm for landscape prints, click Resize Image, and download your 300 DPI print-ready file.
Why do smartphone photos get cropped when printed at 4×6?
Most smartphone cameras shoot in a 4:3 aspect ratio, whereas 4×6 photo paper has a 3:2 (1 : 1.5) aspect ratio. Using the Crop tab or locking the aspect ratio before resizing prevents unexpected edge trimming at the print shop.

Yes. You can select multiple photos in the upload box and batch-resize all of them to 10 × 15 cm at 300 DPI directly in your browser.
Are my personal photos uploaded to a server?
No. Every photo is resized locally in your browser using HTML5 Canvas. Your family and personal photos never leave your device.
