Blur Face in Image

Manually draw boxes over faces or private details, then blur or pixelate them

Click or Drag & Drop an image

No file selected

Done!

Upload a photo, drag a box over each face or private detail you want hidden, and download a version with those exact areas pixelated — no automatic face detection involved.

What is the Blur Face in Image?

Automatic face detection is unreliable at exactly the moments it matters most: it can miss angled faces, small faces in a crowd, or non-face details like license plates and screens entirely. This tool skips detection altogether and lets you draw the boxes yourself directly on the photo, which is slower for a crowd photo but guaranteed accurate for the handful of regions you actually want to hide.

Common Use Cases

  • Blurring bystanders' faces in a photo before posting it publicly
  • Hiding a license plate, ID card or screen visible in the background of a shot
  • Redacting a specific person's face while leaving everyone else in a group photo visible

How to Use the Blur Face in Image

  1. Upload the photo you need to redact.
  2. Click and drag on the image to draw a box over each face or detail you want hidden — repeat for as many regions as you need.
  3. Adjust the blur strength slider if you want a coarser or finer pixelation.
  4. Click the X on any box to remove it, or click Blur Selected Areas & Download to save the result.

Frequently Asked Questions

Why doesn't this detect faces automatically?

Automatic detection can miss faces at odd angles or in low light, and it can't tell you a license plate or ID card also needs hiding — manual selection is slower but always accurate for exactly what you mark.

Can I select more than one face?

Yes, draw as many boxes as you need; each one gets pixelated independently when you download.

What if I draw a box in the wrong place?

Click the small X button in the corner of any box to remove it before downloading, then draw a new one in the correct spot.

Because each region is pixelated using the same block-averaging approach as a dedicated mosaic tool, the hidden detail is genuinely destroyed, not just blurred and potentially recoverable.
