FAQ
How does photo censoring work in the browser?
The tool loads your image onto an HTML5 Canvas element. When you draw a rectangle or use the brush, it applies the chosen effect (pixelate, blur, or solid color) directly to the canvas pixel data. Everything runs locally in your browser — no server is involved.
What censoring tools are available?
There are two selection tools (rectangle and brush) and three censor modes (Pixelate, Blur, Solid Color). Combine them freely: use the brush in blur mode for natural-looking censoring, or the rectangle in pixelate mode for a classic mosaic effect.
Can I undo a censoring action?
Yes. Press Ctrl+Z (or Cmd+Z on Mac) to undo, and Ctrl+Shift+Z to redo. The tool stores up to 30 undo snapshots. Snapshots are taken before each drawing action so you can always step back precisely.
Are my photos uploaded to a server?
No. All processing happens entirely in your browser using the HTML5 Canvas API. Your photos are never sent to any server and never leave your device. There is no account required and nothing is stored.
What image formats are supported?
You can upload JPEG, PNG, and WebP images up to 50 MB. The exported censored image can be saved as PNG (lossless) or JPEG with adjustable quality from 60% to 100%.
How do I download the censored image?
Click the Download button in the toolbar. The file is saved as PNG by default (named original-name-censored.png). Switch to JPEG in the export group and adjust the quality slider to reduce file size before downloading.
