How to blur a photo, face, or video (free, on your device)
Hub guide: blur a face, background, screenshot, or video clip in your browser. Pick the right method for what you are hiding.
People search “how to blur” when they have a photo, a face, a background, a screenshot, or a short clip they need to share without leaking something readable. The right method depends on what you are hiding, not on the word blur itself.

How to blur a photo online free
“Photo” and “image” mean the same thing here. Open the editor, choose your file, drag a box over the region you want covered, and download a new PNG. The original on your phone or computer stays unchanged. Nothing is uploaded to BlurThis servers when you use the on-device browser tool.

Blur vs black bar: which tool?
Use a black bar for phone numbers, OTPs, card digits, and short codes. Soft blur can leave enough contrast for someone to guess. Use blur for faces, messy desks, and backgrounds where a gentle cover is enough. Full comparison: blur vs black bar.
What BlurThis does not do
BlurThis is a manual redaction tool. It does not add cinematic motion blur, replace a live webcam background during a call, or unblur a file someone else already blurred. For live Meet blur, use Google’s built-in background controls. For motion blur effects, use a photo editor built for creative filters.
Export checklist
- Cover every copy of the secret (chat headers, quoted replies, reflections)
- Save a new file, not a layer on the original
- Prefer PNG when you used a black bar
- Zoom to 100% before you send
