What is image blur used for?

Privacy (blur faces, license plates, sensitive info), background de-emphasis, artistic effects, and hiding parts of screenshots before sharing.

Can I blur only part of an image?

Yes. Use the brush or rectangle tool to select the area, then apply blur. The rest of the image stays sharp.

Is image blur reversible?

No. Blur is destructive — the original pixel data is replaced. Always keep the original file separately if you might need it unblurred.

What types of blur are supported?

Gaussian blur (smooth), pixelate (mosaic), and box blur. Each serves different use cases — pixelate is strongest for privacy, Gaussian for aesthetics.

Does blur work on transparent PNGs?

Yes. PNG with transparency is preserved in the output. Blur applies to RGB channels only, alpha is untouched.

Can I blur faces automatically?

No. The tool requires manual selection of blur regions. Use the rectangle tool to select face areas.

Is blurred image data sent to a server?

Never. All blur operations happen in your browser using Canvas API. The image never leaves your device.
