Q: How to choose mosaic size?
A: 20-30px is recommended for faces, 10-20px for text, and 5-15px for pixel-art effects.
Q: Can mosaic be restored?
A: No. Mosaic is irreversible and the original pixel data in masked areas is lost. Keep the original and save the masked version separately.
Q: Are images uploaded to a server?
A: No. All processing happens locally and image data is never sent to any server.
