FAQs
How many pixels is 3.5 x 4.5 cm?
413 × 531 px at 300 DPI. Choose centimetres as the unit and the tool converts it for you.
Can I resize and hit a KB limit together?
Yes — set both and it resizes first, then compresses only as much as needed.
Why does my photo look stretched?
Width and height were both fixed with a different ratio than the original. Keep aspect ratio ticked.
