Image Pixelate & Blur
✓ Link copiedHide sensitive details in any image right in your browser. Drop in a screenshot or photo, draw one or more boxes over the parts you want to obscure — faces, names, addresses, account numbers, license plates — and redact them with a pixelated mosaic or a soft blur. Adjust the block size or blur strength until the underlying content is unrecoverable, then download the cleaned image. Everything runs locally on your device: the picture is never uploaded to a server, so even confidential documents and personal photos stay private.
How to use
Drag and drop an image onto the upload area, or click to choose one. A selection box appears on the image — drag it over the area you want to hide, or drag a corner handle to resize it. Use Add region to mask several areas, and click a box to select it before moving, resizing, or deleting it. Pick the Pixelate or Blur effect and turn up the block size or blur radius until the content underneath is no longer legible. Choose an output format, then click Apply to render the redacted image and Download to save it.
Frequently asked questions
- Are my images uploaded anywhere?
- No. Decoding the image and applying the pixelation or blur all happen locally in your browser using your device's own processing. Your images are never sent to a server, which makes this safe for redacting confidential documents and private photos.
- Is the pixelation or blur reversible?
- The tool permanently replaces the pixels in each selected region with averaged colors, so the original detail is discarded and not stored anywhere. For truly sensitive information, use a large pixel block size or a strong blur radius so the underlying content cannot be reconstructed, and export to a lossless format like PNG so the redaction isn't softened by compression.
- Can I hide more than one area at once?
- Yes. Use Add region to drop additional boxes onto the image and position each one over a different area — every region is redacted together when you apply the effect. Select any box to move, resize, or delete it, so you can mask several faces or fields in a single pass.
