Scan a PDF for personal data — emails, Indian and international phones, Aadhaar, PAN, cards, UPI IDs, IFSC codes — confirm each PII hit, then redact by burning selections into raster pages with no text layer. Scanned image-only PDFs are refused honestly. Local processing, unlimited saves.

Burn text watermarks into a video with 5 position presets (bottom-right default, fixed 24px white on semi-transparent black box). Brand one clip at a time — local FFmpeg work, unlimited saves.
Render audio waveforms as shareable PNG images — audiograms, episode art, visual proof. Turn a soundbite into social content — local rendering, unlimited saves.
Both only cover text visually: highlights draw over text that copies out underneath, and this tool paints opaque black rectangles over the selected pages or areas — the underlying content stays in the file. For permanent removal, use a tool that strips content streams.
Names, IDs, account numbers, prices, and signatures per your policy. Search all occurrences — one missed instance on page 47 defeats 46 redactions.
Treat it as one-way visually, but not as removal: the black regions hide content on screen and in print, yet the text stays in the file and can be recovered. Keep an unredacted master under access control; distribute only redacted copies.
No — redaction runs locally in your browser. Only the final save touches the network — downloads are unlimited.
