How to Blur Sensitive Info in Video
This guide shows you how to blur or redact sensitive information in videos and screen recordings using FastEdit. Draw blur regions over faces, names, emails, or any private data, then scope each blur region to the time range where that content appears.
Walkthrough
- 01
Open FastEdit
Go to fastedit.net. Your files are processed entirely in your browser. Nothing is sent to any server, which is critical when handling sensitive content.
- 02
Drop your image or video
Drag and drop your video, GIF, APNG, or animated WebP file onto the editor.
- 03
Draw blur regions
Use the blur tool to draw rectangles over the areas you want to obscure. You can add multiple blur regions to cover different parts of the video.
- 04
Set time ranges
Each blur region can be scoped to a specific time range. Set when the blur appears and disappears to track content that moves or changes over time.
- 05
Adjust blur strength and export
Set the blur radius high enough that the underlying content is unreadable. Preview the result, then export in your preferred format.
Small things worth checking
- Use a strong blur radius: the content should be completely unreadable, not just slightly obscured.
- For video, blur regions persist across the specified frame range, so you do not need to blur frame by frame.
- Since FastEdit runs client-side, sensitive files never leave your device. This helps when handling private screen recordings or customer data.
- Double-check the exported file by zooming in to ensure no sensitive text or data is readable through the blur.
