About

Captions+ is the ultimate tool for adding external subtitles to YouTube videos. Whether you have a local SRT, VTT, or XML file, simply drag and drop it onto the video to start watching immediately.

🚀 Key Features:

✅ Wide Format Support:
Supports .SRT, .VTT, .SRV3, and .XML subtitle formats. Perfect for downloaded subtitles or archived YouTube captions.

✅ Drag & Drop Interface:
Just drag your file from your desktop and drop it onto the YouTube player. It loads instantly!

✅ Professional Styling (Themes):
Choose from pre-made presets:
- Netflix Style (Yellow text with shadow)
- YouTube Native (White text with background)
- Cinema Mode (Clean white text with outline, no background)
- Or customize fonts, colors, opacity, and text stroke manually.

✅ Interactive Sidebar Browser:
View the entire subtitle track in a searchable sidebar. Click on any line to jump directly to that part of the video.

✅ Perfect Synchronization:
Subtitle out of sync? Use the built-in +/- buttons to adjust timing by 0.5s increments instantly.

✅ Smart Encoding Fix:
Fixes broken characters (mojibake) for languages like Arabic using the smart "Fix Encoding" toggle (switches between UTF-8 and Windows-1256).

✅ Native Look & Feel:
Designed with a "Glassmorphism" UI that blends perfectly with the modern YouTube player.

🔒 Privacy Focused:
All processing happens locally in your browser. Your subtitle files are never uploaded to any server.
