Image privacy redaction
Redact private details in images
Box sensitive areas with solid blackout, mosaic, or blur. Undo changes and export watermark-free.
●Processed in browser Canvas; at least one redaction is required before download
Methods & limits
Safe redaction is reviewable and hard to mis-send—not visually clever
Solid blackout replaces target pixels and is appropriate for IDs, keys, and addresses. Mosaic and blur only reduce legibility and may still be inferred by people or software.
Download stays disabled with zero redactions to reduce accidental sharing of the original. Reopen the export in your system gallery and zoom in; a scaled preview can hide missed edges.
Rectangles are stored in source-image proportions; export redraws the original canvas and flattens every redaction.

Each example lists the job, the result you get, and what still needs a human check against your own files.
01Share a chat screenshot externally
- Task
- Keep the conversation while hiding names, avatars, group names, and notification accounts.
- Result
- Draw solid rectangles and export a new image with every cover flattened into its pixels.
- Check
- Reopen it in the system gallery, zoom into every corner, and inspect quoted messages, thumbnails, and QR codes.
02Hide numbers on a sample ID
- Task
- Show the layout without exposing ID numbers, addresses, or issuing details.
- Result
- Cover every sensitive field with an opaque solid block; no source-pixel layer survives in the export.
- Check
- Do not use blur or weak mosaic for high-risk data. Confirm every cover extends past the text edges.
03Redact a photo, then clean metadata
- Task
- The image shows a license plate or address and may also carry EXIF or GPS data.
- Result
- Redact visible pixels here, then create a sharing copy in the metadata checker.
- Check
- Pixel redaction and metadata cleaning are separate layers. Review the final download after both steps.
FAQ
Redact private details in images · FAQ
Is mosaic safer than blur?
Neither is as reliable as solid blackout. Use opaque blocks for sensitive text, keys, and identity data.
Can I undo a redaction?
Yes. Undo the latest rectangle or clear them all. Rectangular selection keeps the tool usable on touch screens.
Does redaction remove photo location?
Canvas export normally omits EXIF. Use Share Check if you specifically need a metadata scan report.
