Photo Censor

Hide sensitive regions of an image by drawing rectangles that are masked with pixelation, gaussian-style blur, or solid black fill. All processing runs locally through the HTML5 Canvas API - the image never leaves your browser. Multiple regions can be censored on a single image, and each rectangle is applied independently.

1. Click the upload box or drag and drop an image onto it. 2. Choose a censor type: Pixelate, Blur, or Solid. 3. Set the Intensity slider (2-30) - higher means larger pixel blocks or a wider blur radius. 4. Click and drag on the canvas to draw a rectangle over the area to mask. 5. Use Undo to remove the last rectangle, Clear All to reset, or Download to save the result.

Pixelate averages colors inside blocks sized by the intensity value (min 2px) for a mosaic effect. Blur applies a CSS-style canvas blur filter whose radius in pixels equals the intensity. Solid fills the rectangle with pure black (#000000) regardless of intensity. Rectangles smaller than 5x5 pixels are discarded. Output is always saved as a PNG named censored-image.png.
