About blurring parts of a photo
The tool hides any region of a photo — text, passport data, a license plate, a label in the background — in seconds. Three modes are available: Gaussian blur, pixelation (mosaic) or a solid black bar. All three run client-side; the photo never leaves your device.
Works on phone and desktop: drag a rectangle over the region you want hidden with finger or mouse, and the chosen effect is applied inside it. Add as many regions as you need; remove each one with × without losing the original.
Once saved, the masked pixels can't be recovered. To reliably hide passport data, banking details, an address or an account number before sending a document — use the Black bar mode. Blur and pixelation look softer, but at low intensity they can theoretically be reversed.
When to mask part of a photo
Passports and documents
Sending a scan of a passport, driver's license or ID to a chat, bank or marketplace? Cover the document number, date of issue and machine-readable zone with a black bar — that's the standard for contracts and applications.
Text and labels on photos
A stranger's address, a phone number, company details or a personal message visible in the corner of a screen? Cover the text with pixelation or blur — it becomes unreadable.
Chat screenshots and dashboards
Sharing a screenshot of a conversation, your account or a CRM — but you don't want to expose names, emails, balances or order IDs? Mask the sensitive lines one by one.
License plates, price tags, badges
A car-for-sale ad, a parking shot, a frame with an employee badge or price tag — anything that shouldn't identify a specific person or store. Mask the plate or name in 5 seconds.
FAQ
Is the file uploaded to a server?
No. Processing runs in your browser via JavaScript and Canvas. The photo never leaves your device — we don't see, store or transmit it. You can verify this in the DevTools Network tab: there's no image request.
Can the masked part of the photo be recovered?
No, once you've downloaded the result and discarded the original. Blur, pixelation and solid fill irreversibly destroy the underlying pixels. That's stronger than Instagram-style masks where the original sits beneath a layer and can theoretically be peeled back.
Which mode should I pick — blur, pixelate or solid?
For documents and passport data, use the Black bar — it's the strictest option, nothing leaks through. For text and labels in the background, pixelation at 12+ pixels works well. Blur looks softer, but at low intensity (under 10) it can theoretically be reversed by sharpening algorithms.
Can I reliably hide passport data online?
Yes, provided you use the Black bar mode over the document number, date of issue, photo and place of birth. Don't use blur for documents — it isn't reliable. After saving the file, delete the original if you don't need to keep it.
Can I hide text so that it can't be read?
Yes. The most reliable option is to cover the text with a black bar. Pixelation at 12+ also works — neither humans nor AI can recover it. Blur at intensity 30+ is also reliable. Don't use light blur (5–10) for secrets.
How is this different from the 'Blur Face' tool?
It's the same engine, just without the automatic face-detection module. Use this tool when you need to hide text, documents, license plates or any custom region — not a face. If you specifically need to mask faces, the Blur Face tool has an automatic detection button that finds them for you.
Should I download as PNG or JPG?
For photos, choose JPG — file size will be close to the original. PNG is best for screenshots and images with crisp edges (text, icons, graphics). EXIF metadata is stripped automatically — a privacy win, since photos lose GPS coordinates.
