Frequently Asked Questions

How do I apply mosaic blur?

Upload an image, then hold the mouse or a finger and paint over the areas you want to hide to apply the mosaic.

Can I adjust the mosaic size?

Yes. The mosaic block size and brush size can be adjusted independently.

What if I make a mistake?

You can undo the last stroke or clear all mosaic and start over.

Are images sent to a server?

No. The masking happens entirely in your browser.
