What this tool does

This blur and redact tool hides faces, license plates and personal details in a photo. You draw a box over each thing to hide, and it is blurred or pixelated in place.

It is exactly what you need before sharing a photo publicly: obscuring bystanders' faces, a number plate in a car photo, a name badge, a house number, or any detail that should not be on the internet.

It all runs in your browser with the Canvas API, so your photo never leaves your device, which is the whole point when the image is private or sensitive.

You stay in control

There is no automatic face detection and no AI model to download. You draw over precisely the areas you want hidden, which is fast, private and avoids the mistakes automatic detection can make.

Blur or pixelate

Blurring smears an area into a soft smudge, while pixelating breaks it into coarse blocks. Both make the detail unreadable, so you can pick whichever look you prefer.

The hiding is permanent

The covered areas are re-rendered in the downloaded image, so the original detail underneath is gone and cannot be recovered from the saved file. Keep your original if you need it.

Frequently asked questions

Is my image uploaded to a server?

No. The blurring happens entirely in your browser, so your photo never leaves your device, which matters for private or sensitive images.

Can the blur be reversed?

No. The hidden areas are re-rendered in the downloaded image, so the original detail is gone. Keep your original file if you need it.

Does it detect faces automatically?

No. You draw over the areas to hide, which keeps it fast, private and fully under your control, with no AI model to download.

What can I hide with it?

Anything you draw over: faces, license plates, name badges, house numbers, signatures or any private detail you do not want shared.

What is the difference between blur and pixelate?

Blur smears the area into a soft smudge, while pixelate breaks it into coarse blocks. Both make the detail unreadable; choose whichever look you prefer.
