Blur Video
Apply a real gaussian blur to a video — four strengths, rendered entirely in your browser.
Why apply Gaussian blur to video files in browser memory?
Creating soft-focus background videos, aesthetic social media loops, or dreamlike video transitions is easy with Gaussian blur processing across all video formats:
- Website Background Hero Videos: Apply Gaussian blur to ambient background video clips so white headline typography stands out legibly without visual distraction.
- Cinematic Soft-Focus Effects: Create elegant soft-focus transitions for video montages, intro scenes, and presentation backdrops.
- 100% Private On-Device Rendering: Process video files locally inside your web browser without uploading personal video recordings to external cloud conversion servers.
- Four Gaussian Blur Strengths: Choose between Light soft focus, Medium background blur, Strong defocus, and Extreme abstract color wash.
FFmpeg WebAssembly gblur convolution engine
ToolJiffy uses a high-performance client-side FFmpeg WebAssembly pipeline:
The engine applies FFmpeg’s gblur filter (Gaussian blur matrix convolution) across frame pixels in browser memory, re-encoding the result to a standard MP4 container.
Client-side security for private video clips
Uploading private family videos, corporate presentation recordings, or unreleased content to third-party cloud video tools creates severe privacy risks.
ToolJiffy operates on a zero-cloud architecture. By leveraging client-side WebAssembly, video blurring runs 100% locally in your browser memory. Your video files never touch external cloud servers.

Frequently Asked Questions
How do I blur a video online for free without uploading?
Upload your video clip above, select your desired Gaussian blur strength (Light, Medium, Strong, or Extreme), and click Blur Video. ToolJiffy renders Gaussian blur across video frames in browser memory.What is the difference between video blur and video pixelation?
Gaussian blur creates a smooth, soft-focus aesthetic ideal for background video overlays and cinematic scenes. Pixelation creates hard-edged mosaic blocks ideal for censorship.Is my video file uploaded to any cloud server during blurring?
No, 100% private. All Gaussian convolution matrix calculations and H.264 video encoding execute 100% locally inside your browser memory using FFmpeg WebAssembly. Your videos never touch external cloud servers.What four blur strength levels are available?
ToolJiffy provides four strength levels: Light (soft focus effect), Medium (moderate background blur), Strong (heavy defocus), and Extreme (total abstract color wash).Does blurring a video alter the audio track?
No. The audio stream passes through losslessly without re-encoding, staying synchronized with blurred video frames.What video file formats are supported?
ToolJiffy accepts MP4, MOV, WebM, AVI, and MKV video files, exporting a clean web-compatible MP4 file.Why is blurring video useful for website background headers?
