3. Keep Areas I select and drag boxes over what you want hidden, or choose Whole image.
4. Press Download image.

What to hide before sharing

• Faces of people who haven’t agreed to be shown, especially children.
• Number plates in photos of cars and streets.
• House numbers and street signs that reveal where you live.
• Names, emails, phone numbers and account numbers in screenshots.
• QR codes and barcodes on tickets and boarding passes — they can contain your booking details.
• Documents visible in the background of a photo.

Making sure details can’t be recovered

• Use high strength. A light blur can leave text partly readable.
• Cover the whole area, with a margin around it.
• Prefer pixelation with big blocks for text and numbers.
• For highly sensitive data, such as bank details, consider cropping it out entirely with crop image.
• Check the result by zooming in before you share.

Blur and privacy laws

In many places, publishing identifiable images of people can raise privacy or data-protection issues, particularly for children, patients or people in sensitive situations. Blurring faces is a common way for schools, clubs, journalists and businesses to share photos responsibly. Rules differ by country, so check local guidance for your situation.

Also remove hidden data

Blurring hides what’s visible, but photo files can also contain hidden GPS coordinates and device details. Run the blurred image through remove EXIF data before posting, or add a watermark if you’re sharing your own work.

Working on a phone

On a phone, drag with one finger to draw each box. If the picture is small on screen, turn your phone sideways or zoom the page so you can place boxes precisely, and use Clear areas to start again if a box lands in the wrong place.

Blurring screenshots of chats

Before sharing a screenshot of a conversation, blur every name, profile picture and phone number except your own, and any messages that aren’t relevant. Pixelate with a strong setting so short names can’t be guessed from their shape.

How it works

The image is drawn on a canvas in your browser. For blur, each selected box is redrawn with a Gaussian blur filter, clipped to that box. For pixelation, the pixels in each box are averaged in square blocks. The strength scales with the size of your photo so the effect looks the same on small and large images.
