Light and medium run the FFmpeg boxblur filter. Gaussian runs gblur. A soundtrack is kept when the file has one. Clips up to 30 seconds. A photo belongs on Blur image.

How to blur a video

1. Drop a clip you already have. A photo or an audio file is refused here. 2. Leave the light box, or pick the medium box or Gaussian. 3. Press “Blur video” and download.

Light runs boxblur with a radius of 2. Medium runs boxblur with a radius of 6. Gaussian runs gblur with a sigma of 8. Width and height stay the same. A soundtrack is kept and re-encoded to AAC when the file has one. The result is always MP4.

A soft picture, same frame

Blur image softens a photo on the canvas and can save PNG or JPG. This page softens every frame of a short clip and saves MP4. Video gamma changes the midtones. Video contrast stretches them. A hard edge should look softer here, and the clip still plays forward.

The clip stays in this tab

FFmpeg runs in this browser. GustKit does not fetch a video from a link. Close the tab and the file is gone. Clips up to the limit shown next to the button.

How to check the blurred clip

1. Play the download next to the original. 2. A hard edge should look softer. Gaussian should look softer than the light box. 3. If the frame grew, you added a border on another page.

Blur image softens a photo. This page runs boxblur or gblur and saves MP4. Nothing is uploaded.
