Frequently asked questions

Everything you need to know.

Are my images uploaded to a server?

No. All image processing happens directly in your browser using the HTML5 Canvas API. Your files never leave your device.

What image formats are supported?

You can upload PNG, JPG, WebP, GIF (first frame), and BMP files up to 40 MB. The output is always a PNG to preserve quality.

Can I undo my edits?

Yes — the “Reset” button restores the original image so you can start over. Brush strokes are not individually undoable, but reset gives you a fresh start.

Is there a file size limit?

We recommend images under 40 MB for smooth performance. Very large images may be downscaled automatically for the canvas preview, but the download keeps the original resolution where possible.
