How this should help in practice

These sections explain the job in plain language and set expectations for what the tool should do well.

How to blur or pixelate part of an image

To redact an image, drop it into the tool, drag a rectangle over the area you want to hide, and choose blur, pixelate, or a solid fill. Repeat for as many regions as you need, then export the finished image. The rest of the picture stays exactly as it was.

The whole workflow runs in your browser, so the image is never uploaded to a server. That means a sensitive screenshot or document can be redacted and exported without ever leaving your device, and there is no upload queue or wait.

  • Drop in the image
  • Drag a rectangle over the area to hide
  • Choose blur, pixelate, or solid fill
  • Repeat as needed, then export

Why redact before an image leaves your device

A lot of image sharing risk is not about aesthetics, it is about visible details that should not travel further: faces in the background, phone numbers, order details, map coordinates, chat names, or interface elements that were never meant to be public.

A browser-first redaction tool solves that cleanly. It lets you hide exactly the part that matters, keep the rest of the image intact, and export with confidence, all without sending the file to a server first. That privacy is the whole point when the content is sensitive.

  • Redacting screenshots before support tickets, docs, or social sharing
  • Hiding faces or license plates in everyday photos
  • Masking names, addresses, numbers, and account details
  • Cleaning up product, dashboard, or admin screenshots before publishing

Blur, pixelate, or fill: which to use

Blur is best when you want to soften a detail without making the edit look harsh, keeping the image natural while still obscuring what matters. Pixelation is better when you want the redaction to read clearly as intentional, with a visible mosaic over the hidden area.

A solid fill is the strongest option. When a screenshot or document area must be completely unreadable, a flat block leaves no recoverable detail, which makes it the safest choice for highly sensitive information like account numbers or credentials.

FAQ

Common questions

Short answers for the questions people usually have before trying a utility like this.

Is this image redaction tool free?

Yes. Blurring, pixelating, and filling areas of an image is completely free with no sign-up or limits.

Does it upload my image to a server?

No. The editing runs entirely in your browser so the image stays on your device while you redact it. Nothing is uploaded.

When should I blur instead of pixelate?

Blur is better for softening a detail without a harsh look, while pixelation reads more clearly as an intentional redaction. For fully unreadable areas, use solid fill.

Why include a solid fill option?

Some screenshots and documents need a stronger mask than blur or pixelation. A flat fill is the clearest choice when the hidden area must be completely unreadable.

Does it work on mobile?

Yes. The tool runs in any modern browser, including mobile, so you can redact an image directly on your phone before sharing it.
