Frequently asked questions
How do I make a photo 3.5 × 4.5 cm?
Choose the Passport preset, or type 3.5 and 4.5 with the unit set to cm. Crop to fill keeps the face from stretching.
What DPI should I pick?
300 DPI is good for printing. 96 is for screens. A higher DPI gives more pixels for the same size in cm.
Can I also limit the file size in KB?
Yes, for JPG. Type the largest size you can upload and the tool lowers the quality until it fits.
Is my photo uploaded?
No. The photo is resized in your browser.
