Free Blur Video

A blur video tool softens part of a video so details like text, faces or plates can’t be read. This one applies a box blur to one rectangle you define by position and size, during the time range you set, and exports a new MP4.

1. Click Choose files and pick your video. 2. Enter the position, Area width and Area height of the box. 3. Set Effect strength and Start and End. 4. Click Create file, then click Download.

Yes. Set Horizontal and Vertical position to 0 and Area width and Area height to 100, then pick a strength. Set Start to 0 and leave End empty to blur from the first frame to the last.

No. The box stays at the same spot for the whole time range, and the tool doesn’t detect faces. For something that moves, make the box large enough to cover its path, or split the video and blur each part separately.

Yes. Enter Start and End in seconds, and the blur appears only during that range while the full video keeps playing. End has to be later than Start, or you’ll see a message asking for valid values.

Effect strength sets the blur radius, and the tool caps it at 20. For small boxes the cap is lower, a quarter of the box’s shorter side in pixels, so on low-resolution video a tiny box may still show rough shapes.

Yes, it’s free and you don’t need an account. The exported video has no SocQ watermark or logo; the blur you added is the only change to the picture.

No. The blur is applied by FFmpeg in your browser, so footage with private details never leaves your device or reaches SocQ. The video engine downloads once on first use and is reused after that.

You can open MP4, WebM, MOV, MKV, AVI and other common video files up to 100 MB and 10 minutes. The result is an MP4 with H.264 video and AAC audio that keeps the source resolution and sound.

Yes, the page works in mobile browsers on iPhone and Android. There’s no drag-to-select box, so you enter the position and size as percentages, and because the phone does the encoding, longer clips take a while.
