Import or paste
Choose a screenshot or paste it from the clipboard. Face detection runs locally where the browser supports it.
Screenshot privacy
Redact a screenshot online without uploading it.
Open a screenshot locally, mask every private region, then export a new PNG. MaskBeforeShare works in the browser, requires no account and keeps the original image on your device.
Free. No signup. No image upload.
The image is processed in your browser. Review every mask, export fresh pixels, and share the cleaned copy instead of the original.
Mask and review
Face suggestions are automatic. Use boxes or the brush to manually cover names, messages, emails, addresses, account details and QR codes.
Export fresh pixels
Save a new PNG, reopen it and confirm that no readable private detail remains before sharing.
Before sharing
Review the whole frame, not only the main subject.
Screenshots often leak data in browser tabs, notifications, sidebars, filenames, timestamps and status bars.
- Use blackout when text must be impossible to infer.
- Check edges, headers, footers and background windows.
- Share the exported PNG, never the original screenshot.
Does MaskBeforeShare upload screenshots?
No. Normal image processing happens locally in the browser and does not require an account.
Is blur enough for sensitive text?
Strong blur can work visually, but blackout is the safer choice for passwords, account numbers, IDs and confidential text.
What should I redact in a screenshot?
Review faces, names, emails, phone numbers, addresses, IDs, messages, QR codes, account details, tabs and notifications.
