Blur Image

Add your photo — drag it in, click to browse, or paste from your clipboard (Ctrl+V). A selection box appears; drag and resize it over the area you want to hide.

Choose the effect — pick Smooth Blur or Pixelate (Mosaic), and a Rectangle or Circle/Oval shape. To blur the background instead of the subject, switch the mode to "Focus Inside". Set the Intensity and Edge Softness.

Export — hold the compare button to check against the original, then choose JPG, PNG, or WebP and download. ```

Yes. All processing happens locally in your browser, so your image — an ID card, a document, a personal photo — is never uploaded to a server. Nothing is stored once you close the tab. That makes it well suited to exactly the kind of private material you'd want to redact before sharing, since the file never leaves your device.

Smooth Blur diffuses the selected area into a soft haze, which looks natural and is good for gentle effects or background blur. Pixelate (Mosaic) breaks the area into chunky blocks, which is the stronger choice for redaction — hiding faces, license plates, or text. For privacy, pixelate at a high intensity is generally the safer option.

A strong effect is effectively permanent once you export the image — the original pixels in that area are replaced, so there's nothing to "undo" from the saved file. The honest caveat is that a very light blur over small, predictable content (like a few digits) can sometimes be partly reconstructed. So for true redaction, turn the intensity up or use a heavy mosaic.

The tool works on one selection at a time. To hide several areas — say multiple faces — apply the effect to the first, download the image, then upload that result and add the next mask. Repeat until everything is covered. It's a couple of extra steps but lets you keep each mask precisely placed.

Switch the Mask Mode to "Focus Inside". Instead of blurring inside your selection, it blurs everything outside it, leaving your subject sharp — a quick way to fake a shallow-depth-of-field, bokeh-style background. Position the selection over the person or object you want to keep in focus.

Yes. Switch the Selection Shape to "Circle / Oval" for a rounder mask that fits faces and circular objects more naturally than a rectangle. Use Rectangle for text blocks, plates, and document fields. Either shape can be moved and resized to fit tightly around what you're hiding.

No. Only the area inside your selection is affected — the rest of the photo stays exactly as it was. You can export the final image at the same high resolution as your original upload, so the unblurred parts remain crisp. Choose PNG export for lossless quality.

It controls how gradually the blurred area blends into the rest of the photo. A higher feather creates a soft, faded edge that looks more natural, while a low feather gives a hard, defined boundary. For a discreet redaction, a little softness helps the mask blend; for a clear censor block, keep it sharp.

You can upload JPG, PNG, or WebP, and export to any of those three. Pick PNG for lossless quality, JPG for a smaller widely-compatible file, or WebP for the smallest web-friendly size. There's also a compression slider so you can balance file size against quality on export.

Strong. For plates, ID numbers, and faces you want genuinely hidden, raise the Intensity well up and prefer Pixelate (Mosaic) over a light blur. The goal is to remove the detail entirely, not just soften it. Check the result with the "Hold to view original" compare before downloading to be sure nothing readable remains.

Yes. It has a mobile-first layout where the controls become a compact, swipeable ribbon above the preview, so you can place and adjust the mask with touch on Android or iOS. Nothing is installed — it runs in the phone's browser — which is handy for quickly redacting a photo before you send it.

No. There's nothing to download or install and no account to create. The whole tool runs in any modern web browser, on any device, so you don't need a desktop photo editor. Just open the page, add your image, blur or pixelate, and download.
