FAQ

What image formats are supported?

PNG, JPG, WebP, and GIF formats are supported. You can also convert between formats during download.

Is my image uploaded to a server?

No. All image processing happens locally in your browser using the Canvas API. Your images never leave your device.

What does "lock aspect ratio" mean?

When enabled, changing one dimension automatically adjusts the other to maintain the original proportions, preventing image distortion.
