How to use this tool — step-by-step guide

How Subtitle to SRT Conversion Works

Upload a subtitle file in ASS, SSA, VTT, TXT, SBV, or other common formats. ALTools converts it to standard SRT locally in your browser—no upload to a server and no account required.

The tool parses cue timing and text, then normalizes entries to SubRip syntax with sequential numbering. You can see the detected format and entry count before downloading.

Prepare captions for editors and players that expect SRT, clean up exports from other tools, or standardize subtitles before muxing into video.

Because conversion runs on your device, scripts and unreleased dialogue never leave your machine. Processing is fast for typical subtitle files.

Download a standard .srt file ready to import into an editor, upload to a platform, or pair with a video workflow.
