How to Blur or Redact Sensitive Info in a Photo

What to hide before you share an image

Anything that identifies a person or an account is a candidate for redaction. Common items: full names, home and email addresses, phone numbers, account and card numbers, license plates, faces of people who did not consent, and anything on an ID document. Screenshots are especially risky because notification banners, browser tabs, and file paths often reveal more than the part you meant to share.

Blur vs solid block: which is safe?

This is the part people get wrong. A light blur or pixelation can sometimes be reversed, because the original pixels are still there in a scrambled form, and for predictable content like numbers, software can sometimes reconstruct them. A solid block (a filled rectangle) replaces the pixels entirely, so there is nothing left to recover. For anything genuinely sensitive, use a solid block, not a blur.

How to redact a photo

1. Open the image redactor and load your photo or screenshot.
2. Draw a block or blur over each piece of sensitive information.
3. Use solid blocks for anything critical like numbers and IDs; blur is only for casual privacy.
4. Everything happens in your browser, so the image is never uploaded.
5. Export the redacted image, which bakes the redaction into the pixels permanently.

Do not forget the metadata

Redacting what is visible is only half the job. Photos also carry hidden metadata (EXIF), which can include the exact GPS location where the picture was taken, the date and time, and the device. You can black out the address in the frame and still leak your home coordinates through the file's metadata. Strip the metadata as well as redacting the visible content before you post a photo publicly.

Common mistakes when redacting images

• Using a light blur on account numbers or IDs, which can sometimes be reversed; use a solid block.
• Redacting on a hidden layer or a tool that keeps the original, so the data is still in the file.
• Missing information at the edges: notification banners, browser tabs, reflections, and file paths.
• Forgetting EXIF metadata, which can reveal the exact location a photo was taken.

Frequently asked questions

Can a blurred photo be unblurred?

Sometimes, yes. A light blur or pixelation only scrambles the original pixels rather than removing them, and for predictable content like digits, software can occasionally reconstruct what was hidden. For anything that must stay secret, use a solid block instead of a blur so the pixels are replaced entirely and nothing can be recovered.

What is the safest way to hide text in an image?

Cover it with a solid, filled block and export a flattened image, so the pixels underneath are gone rather than merely obscured. Avoid semi-transparent shapes or light blurs over sensitive text. After exporting, zoom in to confirm nothing shows through, and strip the file's metadata as well.

Is my image uploaded when I redact it?

With a browser-based redactor, no. The editing happens on your own device, so the sensitive image never leaves your computer. That is exactly what you want when the whole point is privacy. You can confirm it by redacting with your internet connection turned off; if it still works, nothing is being uploaded.

Does redacting a photo remove its location data?

Not automatically. Redaction covers what is visible in the picture, but the file can still hold EXIF metadata including GPS coordinates, date, and device. Remove the metadata separately with a metadata remover before posting, or you may share your exact location even after blacking out the visible address.

How do I redact a screenshot properly?

Block out every sensitive item, and look beyond the main content: notification banners, open browser tabs, the address bar, file paths, and account names in corners all leak information. Use solid blocks for anything critical, export a flattened image, and take a final zoomed-in look to make sure nothing readable remains.
