Blur phone number in an image
Phone numbers are easy to miss when you're rushing to share a screenshot. Redacted scans the image for any phone-shaped text — US, UK, or international — and covers it with a mask.

How to blur a phone number
- Drop or paste the image into Redacted.
- Click Detect text — phone numbers get masked automatically.
- Add manual masks for handwritten or unusually formatted numbers.
- Pick black box for hard-to-recover numbers, or blur for casual sharing.
- Download the image.
When auto-detect might miss a number
- Handwritten numbers the OCR cannot read
- Very small or angled photos of a screen
- Words spelled out, e.g. "five five five"
- Numbers split across two text blocks far apart
For those cases, draw a manual selection over the area.

The phone-number detector and the OCR engine both run in your browser. The image stays on your device.
FAQ
Will it pick up extension numbers like "x4123"?
Extensions on their own are usually not flagged. The phone number itself will be detected; you can extend the mask manually to cover the extension.
Does it find phone numbers inside a photographed document?
Yes — anywhere the OCR can read a phone-shaped string of digits with separators.
How is this different from drawing a mask manually?
Manual masks still work, and you can always add more. Auto-detect just saves the first pass for the obvious cases.
