Why In-Browser Photo Redaction Matters
When redacting identity documents, bank statements, client screenshots, or photos of minors, uploading files to third-party cloud servers presents substantial data privacy risks. Many online photo editors transmit your unredacted files to remote servers, where they may be cached or logged.
Crate's Blur & Censor tool operates 100% inside your browser via HTML5 Canvas. The pixels never leave your device RAM, guaranteeing that your unredacted documents remain private and unexposed.
👾 Pixelate (Mosaic)
Replaces fine details with oversized color blocks. Ideal for obscuring faces in news photography or YouTube reaction thumbnails.
🌫️ Gaussian Blur
Applies a smooth optical defocus filter. Perfect for softly disguising background license plates, house numbers, or messy desk backdrops.
⬛ Black Bar Redaction
Overwrites pixel data with pure solid black. Best for legal documents, credit card CVVs, Social Security numbers, and confidential passwords.
Frequently Asked Questions
Can someone un-blur or reverse the pixelation?
No. When you export, the underlying pixel data is permanently overwritten and discarded. There are no hidden original layers inside the exported JPG or PNG.
Does this tool reduce the resolution of my photo?
No. The exported image maintains its exact original pixel dimensions (e.g. 4000×3000px). Only the drawn rectangular censor zones are altered.
