How to blur part of an image
Add an image, choose Rectangle or Brush, and draw over the private area. Select Blur and adjust its strength; the preview updates locally. Apply Redaction creates a new flat image at the original resolution.
How to pixelate sensitive information
Choose Pixelate, select a block strength, then draw over text, faces or plates. Pixel blocks are rendered into the image pixels rather than added as a CSS filter.
Blur vs pixelation vs solid redaction
Blur softens detail and is useful for low-risk context. Pixelation replaces detail with blocks but can still be recognized at low strengths. Solid redaction replaces pixels with an opaque color and is safest for passwords, IDs and bank details.
How to redact multiple images
Drop or choose several images. Each thumbnail has its own regions and history, so switching images never copies a selection accidentally. Apply an image individually or apply all edited images, then download a local ZIP.
Are images uploaded?
No. Files never leave your device. Decoding, preview rendering, redaction, re-encoding and ZIP creation all happen in browser memory with no upload endpoint.
Which redaction method is safest?
Use Solid redaction with 100% opacity for highly sensitive information. Blur and light pixelation may not fully prevent recovery or recognition.
Frequently asked questions
Are my images uploaded?
No. Images are decoded, edited and encoded in your browser. Files, names and pixels never leave this device.
Can I blur only part of an image?
Yes. Draw as many independent rectangles or brush strokes as you need, and give each area its own method and strength.
Can pixelation be reversed?
Strong pixelation is harder to recognize, but it is not a security guarantee. Use an opaque solid cover for highly sensitive information.
Which method should I use for sensitive information?
Use Solid redaction at 100% opacity. It replaces the selected pixels instead of placing a removable layer over them.
Can I edit multiple images?
Yes. Add multiple images, edit each independently, and switch between them without losing areas.
Can I download all images as a ZIP?
Yes. The ZIP is generated locally and contains only successfully processed images.
Does the exported image contain the original data?
No. The result is a newly encoded flat image. Original pixels, EXIF GPS data and edit history are not embedded.
