Change Aspect Ratio
Crop a photo to a common aspect ratio — 1:1, 4:3, 16:9, 3:2, or your own custom ratio.

Different platforms and print formats expect different photo shapes, and a photo that looks great at its original proportions can end up awkwardly cropped once a site or printer forces it into a different ratio automatically. This tool puts that choice back in your hands: pick one of the common presets — square 1:1, standard photo ratios like 4:3 or 3:2, or widescreen 16:9 — or enter any custom ratio of your own, then drag and zoom to choose exactly what's kept in frame. Unlike a plain resize, this crops to the new shape rather than stretching the image, so nothing looks distorted. Everything runs locally in your browser via Canvas — your photo is never uploaded to a server.

Frequently asked questions
Which aspect ratio should I pick?
1:1 suits square social posts, 4:3 and 3:2 are common photo-print and camera ratios, and 16:9 matches widescreen video thumbnails and presentation slides. Pick whichever matches where the photo is going.
Can I use a ratio not in the preset list?
Yes — click "Custom" and type any width-to-height ratio you need.
Does changing the aspect ratio stretch my photo?
No — this tool crops rather than stretches, so proportions stay natural. It selects the best-fitting region at your chosen ratio rather than distorting the image to force a shape.
