Hide personal information before you share
Screenshots and photos often contain more than you mean to share: email addresses, phone numbers, account numbers, addresses, faces of bystanders, children’s names or car number plates. Blurring or covering these details before posting online or sending a bug report protects you and others.
Blur, pixelate or black box?
| Effect | Looks | Best for |
|---|---|---|
| Blur | Soft and natural | Faces and backgrounds in photos |
| Pixelate | Mosaic blocks | Clearly marking hidden areas in screenshots |
| Black box | Solid redaction | Passwords, card numbers, ID numbers and anything truly sensitive |
Is a blur always safe?
Not always. A light blur or small pixelation of short text, such as a few digits, can sometimes be reversed by guessing and comparing. For truly sensitive information like passwords, bank or ID numbers, use the black box, or a high strength setting. The black box removes the information completely from the downloaded image.
Tips
- Select a slightly larger area than the text, so no edges of letters remain visible.
- Check the whole image, including reflections, monitors in the background and browser tabs.
- Downloaded images don’t keep the original pixels underneath, so the hidden content can’t be “unblurred” by removing a layer.
- Need to cut away part of the picture instead? Use Crop Image. To reduce the file size afterwards, try the Image Compressor.

Add the image, keep “Hide selected areas” on, drag over the part you want to hide and download the result.

Drag a box over the face and choose Blur or Pixelate. Increase the strength until the face can’t be recognized.
Can blurred text be recovered?+
Heavily blurred or black-boxed areas can’t be recovered. Lightly blurred short text sometimes can, so use a black box for sensitive numbers.

Is my photo uploaded?+
No. Blurring happens in your browser and the image never leaves your device.
