Blur faces in photos
Detect and blur faces in JPG, PNG and WebP photos on your device. Download a PNG and review every face: automatic detection can miss people.
How to blur faces in a photo
- Select a JPEG, PNG or WebP photo. The face detector downloads its model and runtime when needed; the photo is processed on your device.
- Run face blur and inspect the output at full size. Automatic detection applies blur to the faces it finds.
- Download the PNG only after checking every person and other identifying details. Use a region-redaction tool for details the detector misses.
Supported files: Input: JPEG, PNG or WebP, up to 50 MB per file. Output: PNG. No WebGPU requirement; detection uses a local WASM runtime.
A practical example
For an event photo, check the foreground and the crowd in the background. A small profile or partially covered face may be missed even when a larger face was blurred.
Limitations and checks
- Detection can miss small, turned-away or obscured faces. Blur does not guarantee anonymity or satisfy a particular privacy rule.
- Clothing, tattoos, text, reflections and location clues remain visible. Review the whole image before you share.
- The first run needs model/runtime downloads. PNG output can be larger than the source photo.
About Face Blur
Blur the faces detected in a JPEG, PNG or WebP photo on your device and download a PNG. Automatic detection can miss people; inspect every face and other identifying details before sharing. The detector model and runtime download when needed, while the photo stays local.

- Prepare research-image redactions for human review under the applicable protocol.
Frequently asked questions
Does my photo get uploaded to detect faces?
No. Face detection and blurring happen entirely in your browser on your device. The image never leaves your machine — which is the whole point for a privacy tool.
What image formats are supported?
JPEG, PNG, and WebP go in; the blurred result comes out as a PNG.
Will it catch every face?
It detects and blurs each face it finds, but very small, turned-away, or heavily obscured faces can be missed. Review the output before sharing anything sensitive.
Can the blur be reversed?
Blur is baked into the output pixels, but it does not guarantee anonymity. People may remain identifiable from an insufficient blur or other details. Keep the original separately and inspect the result.
Does it work offline?
Local processing does not upload your photo. The first run needs the detector model and runtime downloads; offline reuse depends on which assets remain available in your browser.
