Does this upload my photo to a server?

No. The crop runs entirely in your browser using the Canvas API. Your image data never leaves your device, so the tool works offline once the page is loaded and there's no privacy risk.

3:4 vs 4:5 portrait - which one should I use?

3:4 (taller than 4:5) feels more like a classic vertical photo or magazine page. 4:5 is the Instagram-friendly portrait that gets max feed real estate without being cropped on upload. Pick 3:4 for prints and traditional portraits, 4:5 for social.

What sizes match 3:4?

Common ones are 768×1024, 1536×2048, 2400×3200, and 3024×4032 (iPhone Pro main camera in portrait orientation).

Will I lose quality after cropping?

No. Cropping is a pure pixel-removal operation - the kept pixels stay byte-identical. JPG re-encoding can introduce minor compression, so we encode at high quality (≥0.92) by default.

Does this resize the image too?

No - this tool only crops. The output keeps the pixel resolution of the cropped region. To resize after cropping, use our resize tool or open the result in the AI editor.
