About image masking
Image masking helps hide faces, names, account numbers, API keys, and other private details before sharing screenshots or photos. This tool lets you draw rectangular regions and apply pixelation or blur locally in the browser.
Common uses
- Hide personal details in screenshots
- Blur account numbers, email addresses, and names
- Pixelate faces or private UI regions
- Export a masked PNG, JPG, or WebP copy
Notes
Draw one or more rectangles on the preview, then export the masked image. The original file stays on your device and is not uploaded to the server.
Examples
Blur or pixelate private regions
Switch between blur and pixelate modes before drawing each region, then adjust the strength for stronger masking.
FAQ
Does this image masking tool upload my file?ShowHide
No. The image is decoded, masked, and exported in your browser with canvas APIs. It is not uploaded to UtilPilot servers.
Can I add more than one masked region?ShowHide
Yes. Draw multiple rectangles on the preview. You can undo the last region or clear all regions before exporting.
Should I use pixelate or blur?ShowHide
Pixelate is useful for obvious redaction, while blur can look softer for screenshots. For sensitive details, use a strong effect and check the exported image before sharing.
