Image Redactor

Draw boxes to blur, pixelate or black out faces, names, account numbers and other secrets. The redaction is baked into the pixels on export — truly gone, not a removable overlay.

Higher = stronger blur / bigger pixel blocks.

Drag on the image to add a redaction region. Effect & strength apply to new regions; existing ones keep the look they were drawn with.

No regions yet. Drag a box over anything you want to hide.

Redaction that actually destroys the data

A black rectangle drawn in a document editor or a CSS overlay can often be lifted to reveal what's underneath. HeroTools rewrites the actual pixels: blur and pixelate are re-sampled from the source and drawn back over the region, and black-out paints solid color — then the whole image is flattened to a new PNG. The original is never sent anywhere and the redacted areas can't be recovered from the export.
