OBS Blur Filter
In the fast-paced world of live streaming, one accidental leak of a password, email, or private message can ruin a creator’s reputation overnight. Yet most OBS blur tools are clunky, static, and force you to stop the action just to hide something. Enter EF-Blur Filter—the first OBS plugin that lets you instantly pixelate any part of your stream with a single click of your mouse. Designed for macOS and built for speed, EF-Blur turns your cursor into a privacy superpower, keeping your broadcasts safe without ever breaking the flow.
The Problem
Live streamers often need to hide sensitive information—like passwords, emails, or private messages—on the fly. OBS’s built-in blur tools are static: you either pre-define a region or manually move it, which is slow, clunky, and breaks the flow of your broadcast. No existing filter lets you instantly pixelate any area just by clicking where your mouse is.
Our Solution: EF-Blur Filter
EF-Blur is a lightweight, high-performance OBS plugin that brings real-time, mouse-controlled pixelation to your streams. Click anywhere on a source and an adjustable pixelation square instantly appears under your cursor—perfect for quickly censoring pop-ups, chat messages, or accidental screen shares without ever pausing or disrupting your audience.
