Redact image online and choose the right masking tool
Solid redaction is the safer default for sensitive text; pixelation and blur are better for visual softening.

Redact image online FAQ
Answers for safer image redaction.
When should I redact image online instead of blur?
Use solid redaction for passwords, API keys, ID numbers, bank details, legal data, or medical data.
Does redact image online remove metadata?
This browser canvas export creates a new PNG from the canvas. Still review files carefully before sharing sensitive material.
Can I redact image online with multiple boxes?
Yes. Draw as many redaction boxes as needed and check the redaction count before downloading.
How do I redact QR code and redact barcode regions?
Choose Find QR codes & barcodes, inspect each candidate, expand its margin if needed, and apply a fully opaque cover. You can delete false positives. Decoded content is displayed only as text and never opens automatically. Browser support and detected formats vary; manual selection is always available.
How can I find text to redact?
Recognize the processed image, then search for a name, number, or phrase. Select a matching line to create a candidate and confirm its solid cover. To redact sensitive text in image files, review every relevant line: this tool does not automatically identify all sensitive information.
What happens to recognized text after redaction?
Changes to regions clear recognized text, search results, and decoded values. New recognition, exported PNGs, and images passed to other tools use the processed image. Undo retains region geometry without restoring recognized content. Unconfirmed candidates are not covered in exports.
Does zero detection mean my image is safe?
No. Detection may miss codes or text, and some browsers do not support barcode detection. Manually inspect the complete image and exported PNG before sharing.
