Subtitle Format Converter

The Subtitle Format Converter supports the most popular subtitle formats: SRT (SubRip), VTT (WebVTT), ASS/SSA (Advanced SubStation Alpha), and SUB (MicroDVD). You can convert between any of these formats or extract the dialogue as plain text.

Simply upload your SRT file using the file selector, choose "Plain Text (TXT)" as the output format, and the tool will automatically extract all dialogue text. You can optionally include timestamps in the text output by checking the "Include timestamps" option.

Yes! Upload your VTT file, select "SubRip (SRT)" as the output format, and the tool will convert it automatically. The conversion preserves all timing information and dialogue text while adapting to the SRT format structure.

Yes, when converting between subtitle formats (SRT, VTT, ASS, SUB), all timing information is preserved and converted to the appropriate format. When converting to plain text, you can choose to include or exclude timestamps.

SRT (SubRip) is the most widely supported subtitle format, using comma-separated timestamps. VTT (WebVTT) is the web standard for HTML5 video, using dot-separated timestamps and supporting additional features like positioning and styling. Both formats work for most use cases.

The tool uses a combination of file extension and content analysis to detect the format. It checks for format-specific markers like "WEBVTT" for VTT files, "[Script Info]" for ASS files, timestamp patterns for SRT, and frame-based timing for SUB files.

This tool works with subtitle files only, not video files directly. If you have a video file, you would first need to extract or download its subtitle track (many video players and online services offer subtitle downloads), then use this tool to convert or extract the text.

Absolutely! All subtitle processing happens entirely in your browser. Your subtitle files are never uploaded to any server or transmitted over the internet. The conversion is completely client-side, ensuring your subtitle files remain private and secure.

ASS (Advanced SubStation Alpha) is a subtitle format that supports advanced styling, positioning, effects, and animations. It's commonly used for anime subtitles and projects requiring complex subtitle presentation. When converting to ASS, basic styling is applied.

Yes! After conversion, the output is displayed in an editable text area where you can make any changes you need before copying or downloading. This is useful for quick corrections or adjustments to the converted content.

Including timestamps is useful for reference purposes, creating study materials, or when you need to know when specific dialogue occurs. It's helpful for video editing, creating transcripts with timing references, or analyzing dialogue timing patterns.

Basic text content and timing are always preserved. When converting from ASS (which supports advanced styling) to simpler formats like SRT or VTT, styling information is removed and only the text and timing are kept. Converting from simple formats to ASS adds default styling.

The tool can handle most subtitle files without issues, but very large subtitle files (over 5MB) may cause performance issues depending on your device. Most subtitle files are much smaller than this (typically under 500KB), so this shouldn't be a concern for normal use.

If conversion fails, first verify that your subtitle file is properly formatted and not corrupted. Try opening it in a text editor to check. Make sure the file uses one of the supported formats (SRT, VTT, ASS, SUB). If issues persist, the file may have non-standard formatting that requires manual correction before conversion.
