SubFix - Subtitle Anchor & Customizer

Lock subtitles to the bottom on Netflix, Prime Video & JioHotstar. Prevent top jumps, customize size, font and contrast.

Tired of subtitles jumping straight to the top of your screen over actors' faces during intros, opening credits, or title cards? SubFix is a lightweight extension engineered to permanently anchor and customize subtitles across your favorite streaming services. 🔥 KEY FEATURES: • Permanent Bottom Pinning: Overrides platform styling so subtitles stay docked at the bottom throughout the entire movie or episode. • High-Contrast Background Pills: Add a dark semi-transparent pill behind text for crystal-clear readability against bright scenes. • Typography & Position Tuning: Adjust vertical margin offsets, font sizes, and custom fonts. • Supported Platforms: Netflix, Amazon Prime Video, and JioHotstar / JioCinema. • Zero Lag & Battery Friendly: Instant CSS injection with MutationObserver fallback. No background polling or CPU overhead. • Privacy First: SubFix runs 100% locally in your browser. No video streams, watch histories, or keystrokes are ever read or transmitted. ⚡ HOW TO USE: 1. Install SubFix. 2. Open any movie or show on Netflix, Prime Video, or JioHotstar. 3. Turn on subtitles — SubFix automatically locks them to the bottom. 4. Click the SubFix icon in your Chrome toolbar to customize fonts, size, or contrast styling. Built with ❤️ by SummerLabs (https://summerlabs.in)
