Convert AIFF to a VTT caption file

AIFF is the lossless audio format native to macOS and professional Apple tools such as Logic Pro. VTT (WebVTT) is the caption format HTML5 video players accept natively. SnailText decodes the AIFF using a one-time codec pack, transcribes the speech with the Whisper model, and writes a phrase-level VTT, all on your machine.

Lossless input gives Whisper clean audio. You get a separate .vtt file ready to use in any web player.

How to convert AIFF to VTT

  1. Open the Transcribe files screen in SnailText.
  2. Add your AIFF audio file (or a folder of them).
  3. Choose VTT as the output before you run it.
  4. Run it. The .vtt file is saved next to your audio.

AIFF to VTT free, without uploading the file

Online converters upload your AIFF to a server. SnailText does it locally: the file stays on your machine, there is no length limit, and the free tier has no watermark. AIFF uses a one-time codec pack the app downloads for you.

If you need SRT instead of VTT, the AIFF to SRT page covers that. SnailText exports both, you just pick before the run.

AIFF to VTT FAQ

How do I convert an AIFF file to VTT?
Install SnailText, open Transcribe files, add your AIFF, choose VTT as the output, and run it. It generates the VTT locally. AIFF uses a one-time codec pack the app downloads for you.
What is the difference between AIFF to VTT and AIFF to SRT?
VTT (WebVTT) is the web-native format for HTML5 video and streaming. SRT is older and more widely supported in media players and editing tools. SnailText generates both, you pick before the run.
Can I use the VTT from an AIFF file on YouTube?
Yes. YouTube accepts VTT as a caption file. Once SnailText generates the .vtt from your AIFF, upload it to your video on YouTube as a subtitle track.
Does SnailText burn the subtitles into the video when I use AIFF to VTT?
No. SnailText writes a separate VTT file and does not hardcode captions into the video. That keeps the subtitles editable and lets you attach them in any player or editor. If you want them burned in, overlay the file in a video editor afterward.
