IconVault's Redact Image tool permanently covers names, numbers, faces and any sensitive region with a solid color bar you draw yourself. Unlike blur, the covered pixels are destroyed, not hidden, and because the image is re-encoded, the redaction cannot be undone and the file's metadata is removed too.

It is free and runs 100% in your browser, so sensitive documents never leave your device. Pick any fill color (black by default, via color well or hex), draw multiple resizable boxes, then export as JPG, PNG, WebP or the original format. Go Pro for unlimited runs across all 50+ IconVault tools.
