What changes in this conversion

  • SRT opens almost everywhere, so the converted file will work on devices and programs that refused the original ASS.
  • Timecodes and dialogue text are converted exactly. Styling such as fonts, colors and on-screen positioning is only kept if SRT supports it.

How to use

  1. Add your ASS file

    Drag the ASS file onto the drop area above, or click it to pick a file from your device. You can add several files at once.

  2. Confirm SRT as the output

    SRT is already selected as the output format on this page. This format converts straight through with no extra settings.

  3. Run the conversion

    Press the convert button. Processing happens on your own device, so the time depends on your computer rather than a server queue.

  4. Download the SRT file

    When it finishes, download the SRT file. Converting multiple files gives you the option to download them together as a ZIP.

Frequently asked questions

Is converting ASS to SRT really free?

Yes. ASS to SRT conversion is completely free with no signup, no watermark, and no daily limit on the free plan for ordinary use.

Are my ASS files uploaded to a server?

No. The conversion runs entirely inside your browser using WebAssembly, so the ASS file never leaves your device. That is also why it works without an internet connection once the page has loaded.

Does the SRT file get bigger than the ASS?

It can go either way. Both formats are lossless, so nothing is thrown away — the size difference comes from how each one packs the same data.

Is there a file size limit for ASS to SRT conversion?

The free plan handles files up to 200MB. Because processing happens on your own device, very large files depend on your computer's memory rather than a server quota.
