Is my image uploaded to a server?

No. This tool runs entirely in your browser using HTML5 Canvas. Your image data never leaves your device.

Can I undo a mistake?

Yes! You can press Ctrl+Z or click the Undo button to remove the last redaction stroke.

Does it remove metadata (EXIF)?

Yes. The downloaded image is a fresh Canvas export, so original metadata like location is stripped automatically.

What is the "Pixelate" mode?

It creates a mosaic effect (standard censorship style) often used to hide faces or logos while keeping the context.

Yes, 100% free with no watermarks and no signup required.

What file formats are supported?

We support JPG, PNG, WebP, GIF, and BMP images.

Why Use This Redactor?

⚡ Instant & Offline

Because there is no upload/download lag, redaction is instant. It also works completely offline. Load this page once, and you can use it on a flight or in a secure zone without internet.
