SubtitleFix is a free, web-based subtitle converter and timing adjustment tool designed to repair out-of-sync or incorrectly formatted subtitle files. It primarily targets video enthusiasts and creators working with common plain-text subtitle formats. Key Features and Capabilities
The platform provides a modular set of tools to resolve common playback mismatches:
Format Conversion: Automatically converts text files between .srt (SubRip) and .sub formats (srt2sub / sub2srt).
Time Shifting: Allows you to push captions forward or backward by a uniform duration (minutes and seconds) if the dialogue is consistently out of sync.
Frame Rate Calibration: Stretches or compresses subtitle timestamps to account for frame rate mismatches, such as converting between 23.976 fps and 29.975 fps.
Subtitle Merging: Features a merge 2CD - 1CD utility to combine two separate subtitle files into a single sequence, which is ideal for multi-part video archives.
HTML Clean-Up: Automatically strips out stylistic HTML markup like , , or font tags that may clutter the screen or fail to render in specific media players.
Quality Check: Scans files for structural errors, such as overlapping timestamps or durations shorter than 0.5 seconds, and outputs an error report. Alternative Tools
