Common questions

Does resizing reduce image quality?

+

Downscaling rarely causes visible quality loss. Up-scaling beyond 200 % can introduce softness — for best results, pair the resizer with our AI Enhance tool to sharpen enlarged images.

Is my image uploaded to a server?

+

No. All processing happens inside your browser using the Canvas API. Your file never leaves your device.

What dimensions should I use for an Instagram post?

+

Instagram recommends 1080 x 1080 px for square posts, 1080 x 1350 px for portrait, and 1080 x 566 px for landscape. Our preset menu includes all three options.
