How to Blur a Video on Android or Chromebook
November 3, 2026
Short answerOpen Blur The Video in Chrome, load the video, drag a box over the area, set the effect and timing, and export. It runs inside the browser, so it works on Chromebooks and in Chrome on Android without installing an app.
Chromebooks can't run most desktop video editors, and Google Photos on Android has no tool to blur one area of a video. A browser editor fills that gap. Chrome supports the recording features the editor needs, so exporting works there.
Typical jobs: blurring a classmate in a school project video, hiding a license plate in a dashcam clip before posting it to a local group, or covering personal details in a screen recording made on a Chromebook.
Step by step
- Open Chrome and go to the Blur The Video editor.
- Choose your video from the Files app (Chromebook) or your gallery (Android). It is processed on your device, not uploaded.
- Drag on the video to draw a box over what you want hidden. Adjust it with the handles.
- Choose Blur, Pixelate or Solid and set the strength.
- Set the timing with Start here and End here.
- Add any other boxes, trim if needed, and export. The file lands in your Downloads folder.
Chromebook tips
- Keyboard shortcuts work: Space to play, arrow keys to jump, Ctrl + D to duplicate a box, Ctrl + Z to undo.
- Chrome can usually export MP4, which is the best choice for sharing. WebM is the fallback.
- Lower-end Chromebooks can struggle with long 4K clips. Trim to the part you need and close other tabs during export.
- School or work-managed Chromebooks often block app installs. A browser tab usually still works.
- Use Save project to keep your boxes if you need to stop and continue later.
Android tips
- Use landscape mode. The editor is designed for desktop first, so a small portrait screen is cramped.
- Keep the screen on and Chrome in front during export. The video is rendered by playing it through in real time, and Android may pause background tabs.
- Draw boxes a bit larger than the target, since finger input is less precise.
- If a file won't load, the phone may have recorded it in a codec Chrome can't play (some HEVC files). Re-record in H.264 or convert first.
Limitations
There is no automatic face or object tracking. For moving subjects, use one larger box or a chain of short ones; the guide on blurring a moving object explains how. Exports are free with a small watermark, which costs $0.99 to remove for one video or $19.99 for a lifetime license. If you're working on a desktop instead, see how to blur a video on Windows.
FAQ
Can Google Photos blur part of a video? No. Google Photos can trim, stabilise and apply filters, but it has no tool to blur a specific area of a video.
Is my video uploaded? No. The editing and export happen locally in Chrome on your device. The video itself is never sent to a server.
Why is my export slow? Export plays the video through in real time, so it takes about as long as the clip. Older devices may need longer for high-resolution files.
Which browser should I use on Android? A current version of Chrome. Other browsers may not support the recording features the export needs.
