RedSub – Universal Subtitles for Movies & Series

Find, load, and sync subtitles for movies and series directly on your video.

RedSub helps you search, upload, and synchronize subtitles for video content across web pages. If a video is missing captions or has out-of-sync audio, RedSub allows you to load matching subtitle tracks or upload your own subtitle files directly into the browser. KEY FEATURES • Subtitle Search Find matching subtitle tracks for your video content with quick search filtering. • Custom Subtitle File Support Load your own local subtitle files (.srt, .vtt, or .ass formats) directly into the player. • On-Screen Subtitle Rendering Displays clean, high-legibility subtitle captions synchronized over HTML5 video elements. • Precision Timing Controls Adjust subtitle timing forward or backward in 0.5-second increments to fix out-of-sync audio. • Dual Visual Themes Choose between Dark Mode for low-light environments and Light Mode for daytime viewing. • Privacy-Focused Processing Local subtitle files are parsed directly inside your browser without uploading your personal files to external servers.
