Ever wanted to share a chat screenshot, order info, or delivery receipt — only to realize your phone number is right there? Posting it exposes your number. Photoshop is overkill. Blurring phone numbers online takes seconds.

When to blur phone numbers

  • Sharing screenshots: shopping and delivery screenshots hide numbers first
  • Customer service: sharing chat logs with others — redact both sides' numbers
  • Second-hand trading: protect contact info on Xianyu, Zhuanzhuan
  • Work records: expense reports, shipping labels with sensitive numbers
  • Social sharing: protect privacy on WeChat Moments and Weibo

Blur phone numbers with PixelForge

Open the PixelForge Mosaic Tool — browser-local, private and secure.

Step 1: Upload the screenshot containing the phone number. Step 2: Box-select the number area, and the tool mosaics it. Step 3: Adjust the mosaic strength to fully hide the digits. Step 4: Download the redacted image and share safely.

Blurring tips

  1. Cover the whole number — a half-hidden number can be guessed
  2. Check nearby info too: names, addresses, card numbers
  3. Use coarse mosaics — fine ones can sometimes be reverse-engineered
  4. Mosaic every sensitive spot; one screenshot may have several

FAQ

Can a mosaiced phone number be recovered?

No — coarse mosaic is permanent. The digits are fully covered and can't be restored, so your number stays private.

How do I blur all numbers in one image?

Box-select each one. The mosaic tool supports multiple selections, so you can cover every number, address, and other sensitive info in one screenshot.

Does the rest of the image get blurry?

Only the selected areas are blurred; the rest stays crisp. For full-image blurring, use the [image blur](https://img-tools.top/mosaic) option.

Can I redact other sensitive info too?

Yes — the same tool blurs names, addresses, card numbers, QR codes, anything you need to hide in one go.
