Is my image uploaded to a server?

No. All masking happens locally in your browser — the image never leaves your device and no sign-in is required.

Which file types work?

JPG, PNG and WEBP work directly. HEIC from iPhone needs to be converted to JPG or PNG first.

Which mask type should I pick?

For maximum privacy use a black box or pixelate at high strength. Blur looks subtle but can rarely be reversed. White box is great for receipts and documents.

Can I mask several areas in the same image?

Yes. Add as many selections as you like, mix mask types, and download everything as a single finished image.
