Automatic Text & Username Redaction
Blur Names & Usernames in Screenshots
Blur ID automatically finds every name, username, avatar and phone number in a screenshot and blurs them in one tap. No drawing boxes by hand, no uploading — the AI runs entirely on your iPhone.
How do you blur a name in a screenshot?
Open the screenshot in Blur ID: its on-device AI detects names, usernames, avatars and other sensitive text automatically and blurs them all at once. Tap any detection to toggle it, switch to a solid or immersive redaction style for text you really need hidden, then export a clean copy. The whole process takes a few seconds and nothing is uploaded.
Blur every name in 4 steps
- 1
Import the screenshot
Open Blur ID and pick the screenshot from your photo library — a chat thread, a group conversation, a social feed, anything.
- 2
Let the AI find the names
In about a second, Blur ID detects display names, usernames, avatars, faces and phone numbers — including the tiny ones manual editing always misses.
- 3
Fine-tune what stays hidden
Tap any detection to un-blur it, add a manual region for anything extra, and pick the style: blur, pixelate, solid, or immersive redaction that removes text naturally.
- 4
Export and share
Save a clean copy with the redaction baked in. The original stays untouched in your library.
Why blur names before sharing a screenshot
A screenshot almost always contains more identities than the one you mean to share. Post a group-chat thread and you have exposed every member's name and avatar; share a funny reply on Reddit or X and the other person's username is now searchable by millions.
Blurring names is basic screenshot etiquette — and in work contexts it can be a compliance requirement. Colleagues' names in a Slack export, customer names in a support thread, or a phone number visible in a notification banner can all turn a harmless share into a privacy incident.
What Blur ID detects automatically
- Display names and usernames in chat apps, social feeds and comment threads
- Profile pictures and avatars — replaced or blurred so identities stay hidden
- Faces in embedded photos, including small ones
- Phone numbers and other sensitive text strings
- Anything else via manual regions — draw over an address, an email, an order number
Blur vs. solid redaction: which hides text better?
An honest note: researchers have shown that lightly blurred or pixelated text can sometimes be reconstructed. That is why Blur ID offers solid and immersive redaction styles in addition to blur. For names you'd merely prefer to hide, a blur looks natural; for text that must stay secret — numbers, addresses, IDs — use the solid or immersive style, which removes the information completely.
Whatever style you choose, Blur ID re-renders the exported image with the redaction baked in, so the hidden pixels are simply not present in the file you share.
Works with screenshots from any app
Blur ID processes the image itself, so it doesn't matter where the screenshot came from: WhatsApp, iMessage, Instagram, X, Reddit, Slack, Discord, Telegram, Signal, Tinder — if you can screenshot it, Blur ID can redact it.
Frequently Asked Questions
How do I blur a name in a screenshot on iPhone?
Open the screenshot in Blur ID. The AI automatically detects and blurs names, usernames and avatars in about a second — no manual selection needed. Adjust anything you like, then export a clean copy.
Can it blur every username in a group chat at once?
Yes. Blur ID detects all names and avatars in the screenshot in one pass and blurs them together. You can then tap individual detections to keep some visible — for example, leaving your own name while hiding everyone else's.
Is blurred text really unreadable?
The exported image is re-rendered with the redaction baked in, so the covered content is not stored in the file. For highly sensitive text, use the solid or immersive redaction style rather than a light blur — light blurs on text have been reversed in research settings.
Do my screenshots get uploaded anywhere?
No. All detection and redaction runs 100% on your iPhone. Blur ID works fully offline — you can even use it in airplane mode — and your images never touch a server.
