Blur Faces in Photos

Automatic face detection

When your browser exposes the FaceDetector API, Vizua asks it to locate faces and creates a selectable region for each result. Detection is optional and can be unavailable or incomplete. The tool switches to manual mode when the API is missing or fails.

When to use this tool

It's useful any time you need to share a photo while protecting someone's identity — social media posts, news articles, company documentation, or event photos. You can blur every face at once or pick and choose, depending on what the situation calls for.

Manual selection mode

Automatic detection works best for faces that are front-on, well-lit, and large enough in the frame. If someone is turned to the side, partially hidden, or appears small in the background, switch to manual mode and drag a rectangle over the area you want to blur. Both modes can be used together on the same image.

Adjusting blur strength

The slider controls the blur radius or mosaic block scale. A stronger setting can obscure more detail, but no setting guarantees anonymity or prevents reconstruction. Review the full image for missed faces, reflections, name badges, locations, and other identifying clues before sharing.

Output and browser processing

PNG, WebP, and JPEG inputs are re-encoded in the corresponding output family. JPEG and WebP use a fixed lossy quality, while PNG uses lossless coding for the rendered raster. Metadata and profiles are not preserved. The selected image is not sent to Vizua’s image-processing server, although the page can still request required assets and other site features.

What you can do with Blur Faces in Photos

Detect faces when supported or select regions manually, then apply blur or pixelation in your browser. Review the result before sharing.

Blur Faces in Photos is designed for quick, repeatable work in a modern browser. The controls on this page let you prepare the result without installing software or creating an account.

How to use Blur Faces in Photos

1. Select or drop the file you want to process, or enter the information requested by the tool.
2. Review the available settings before processing, especially format, dimensions, quality, color, or other details that affect the output.
3. Inspect the result, download the new file, and keep the original unchanged in case you need another version.

Private by design

Your files never leave your device. All processing happens locally in your browser.

Tips for better results

• Start with the cleanest source available; a small, blurry, or heavily compressed file contains less detail to preserve.
• Check dimensions and format before downloading so the result matches the site, app, printer, or platform where you will use it.
• For large files, close unnecessary tabs and test one representative file before processing a full batch.
• Open the downloaded result once before sharing it or replacing an original.

Where Blur Faces in Photos fits in a workflow

Use Blur Faces in Photos for one-off adjustments or as a preparation step before publishing, sharing, archiving, or continuing the edit in another application. When batch processing is available, validate the settings on a small sample first and then apply them to the remaining files.
