Is my image uploaded to blur it?

No. The blurring happens entirely in your browser. The original, unredacted image never leaves your device — which is the whole point of a privacy tool.

Can the blur be reversed?

No. Blur, pixelation and redaction are baked into the exported image’s pixels. The hidden information cannot be recovered from the downloaded file.

What is the difference between blur, pixelate and redact?

Blur softens the area, pixelate replaces it with coarse blocks, and redact covers it with solid black. For maximum certainty on text (like account numbers), redaction is the safest choice.

Can I adjust a region after drawing it?

Yes. Click any region to select it, then drag to move it, use the handles to resize, or press Delete to remove it. Ctrl+Z undoes your last change.

Pixelate an image

Apply a classic pixelated mosaic to any part of an image — or all of it. Drag over a region, tune the block size, and export. Everything runs locally in your browser.

Privacy-first: every image is processed locally in your browser. Nothing is uploaded, stored or transmitted to any server.

The mosaic effect, under your control

Pixelation replaces a region with coarse uniform blocks — the visual language of censorship, anonymization and deliberate concealment. Because the block size is adjustable, the same tool covers subtle anonymization (small blocks over a face) and the heavy, unmistakable mosaic used for content that must clearly read as hidden.

Real downsampling, not a filter

The blocks are produced by destructively downsampling the selection to a handful of pixels: the original detail is discarded, not covered by a reversible layer, and the result is baked into the exported file. Select one region or several, mix pixelation with blur or black bars on the same image, and undo freely while editing.

Private by architecture

The image is pixelated in your browser and exported from your browser — no upload, no server-side processing, no copy retained anywhere. For photos being pixelated precisely because they show something sensitive, that is the only arrangement that makes sense.
