Why use this tool
Made for sensitive material
When you share an image, whether it is a screenshot, a photo of a document, or a scanned form, it may contain personal information that was not meant to be shared.
Hiding that information before sharing is a simple, responsible step. It protects the privacy of the people whose data appears in the image and reduces the risk of accidental exposure.
This tool covers any visible sensitive region with your choice of effect and runs entirely in your browser so your image never leaves your device.
Questions
Frequently asked questions
What kind of sensitive information can I hide?
Any visible data in an image: full names, email addresses, phone numbers, ID numbers, passport details, addresses, signatures, or other private information.
Which redaction style is most secure?
Black Box is the most secure. It replaces the selected area with solid black pixels, making recovery of the hidden information impossible.
Can I hide information in images I am posting on social media?
Yes. Upload your image, hide the sensitive parts, download the result, then post the downloaded version. The original never leaves your device.
Is this GDPR or HIPAA compliant?
This tool processes images entirely in your browser and never transmits data. Whether it meets specific compliance requirements depends on your organization.
Does this work on iPhone or Android?
Yes. Open this page in your mobile browser, upload a photo from your gallery, and use touch gestures to draw over the areas you want to hide.
Can I hide a face as well as text?
Yes. The tool works on any region of the image: faces, handwriting, printed text, signatures, logos, and more.
How many areas can I hide in one image?
There is no limit. Draw as many selection boxes as you need and each one adds a new hidden region.
What if I make a mistake?
Click Undo to remove the last selection and redraw it. The original image is never modified.
Can I hide information in a scanned document?
Yes. Scan the document to an image file, upload it here, draw over the sensitive fields, and download the redacted version.
