Short answer: Yes, superwhisper transcribes audio and video files, but there are two things worth knowing before you rely on it. File transcription is a Pro feature, not part of the free tier. And its offline models run best on Apple Silicon Macs, so Windows file transcription is a second-class experience.
If you are searching this because you want to drop a recorded interview, lecture, or meeting into an app and get a transcript back, superwhisper can do that well. This page walks through exactly how, where it shines, and where a free local alternative fits.
Does superwhisper transcribe files?
Yes. The superwhisper desktop app lets you upload a recorded audio or video file and get a transcript back. It handles the common cases: meeting recordings, lectures, interviews, podcast episodes, and voice memos. Supported formats include MP3, MP4, M4A, WAV, WEBM, and most others you are likely to have.
The important qualifier: file transcription is a Pro feature. The superwhisper free tier is generous for live work. It gives you unlimited use of the small local models, dictation into any app, meeting recording, and 100+ languages. But uploading a recorded file to transcribe is gated behind a paid plan.
There is also a separate, distinct tool. superwhisper runs a free browser transcriber at superwhisper.com/transcribe. That one is cloud-based and capped at 10 minutes per file. It is handy for a quick one-off, but it is not the same thing as the desktop app’s local file transcription. Do not confuse the two: the browser tool uploads your audio, the desktop app does not.
Is superwhisper file transcription local?
Yes, on the desktop app. When you transcribe a file with a local Whisper model, everything runs on-device. Your audio never leaves your machine, and there is no per-file length cap. That is the real strength of the desktop product: private, offline transcription of arbitrarily long recordings.
This is the opposite of the browser tool at superwhisper.com/transcribe, which is cloud-based and uploads your file. If privacy is the point, the desktop app with a local model is the version you want.
The Mac-first reality, and the Windows caveat
Here is the fair-but-important nuance. superwhisper’s offline models only run really well on Apple Silicon Macs. Apple’s unified memory and Neural Engine give whisper.cpp-style local inference a big advantage, and superwhisper is tuned for it. On an M-series Mac, local file transcription is fast and smooth.
On Windows, the story is reported to be weaker. By superwhisper’s own guidance and community reports, the larger local models are slower there, and a dedicated NVIDIA GPU helps them keep up. superwhisper is available on Windows, and file transcription works there, but offline performance is described as second-class compared to the Mac experience. If you are a Windows user who wants local file transcription as a first-class feature, this is the single most important thing to weigh.
superwhisper vs SnailText for file transcription
Both are local voice tools, but they make different tradeoffs. Here is a side-by-side focused on file transcription:
| superwhisper | SnailText | |
|---|---|---|
| Transcribes uploaded files | Yes (Pro only) | Yes (free tier included) |
| Formats accepted | MP3, MP4, M4A, WAV, WEBM, more | MP3, MP4, M4A, WAV and more |
| Runs locally / offline | Yes (desktop app) | Yes |
| Mac performance | Excellent (Apple Silicon) | Good |
| Windows performance | Reported slower, GPU helps | On-device on Mac and Windows |
| Speech models | Whisper family | Whisper + Parakeet TDT |
| Speaker diarization | Yes (speaker labels) | No |
| Subtitle export | Check superwhisper for current format support | SRT, VTT, plus TXT, MD, JSON |
| Languages | 100+ | 99 |
| Modes / LLM cleanup | Yes (Modes, BYOK LLM) | Optional local LLM (Pro) |
| Free tier | Live dictation, no file uploads | Unlimited compact models, incl. files |
| Pro pricing | $8.49/mo · $84.99/yr · $249.99 lifetime | $7.49 / month · $89 / year |
A note on subtitles: SnailText exports SRT and VTT subtitle files directly, alongside TXT, Markdown, and JSON. If subtitle output is your reason for transcribing, that is worth knowing. Check superwhisper’s own docs for its current export options, since those can change.
Where each one wins
Pick superwhisper if:
- You are on an Apple Silicon Mac and want best-in-class local transcription speed.
- You need speaker diarization, meaning speaker labels on long multi-person recordings. SnailText does not do this.
- You want its mature Modes system and bring-your-own-key LLM cleanup for polishing transcripts.
- You are already paying for Pro for dictation and file transcription is a bonus.
Pick SnailText if:
- You want to transcribe files on the free tier without paying. superwhisper gates file transcription behind Pro at $8.49/month. SnailText includes file transcription with its free compact models.
- You are on Windows, or you split time between Mac and Windows, and you want the same performance on both. SnailText treats Mac and Windows as equals, while superwhisper’s Windows offline models are slower.
- You need SRT and VTT subtitle files for video work.
- You want folder and drag-and-drop batch handling for local files.
The honest tradeoff: superwhisper is the more feature-complete tool for a Mac power user, especially with diarization and LLM cleanup. SnailText’s edge is that file transcription is free, works identically on Windows, and exports subtitles.
Honest verdict
Does superwhisper transcribe audio files? Yes, and it does it well. On an Apple Silicon Mac it is one of the best local transcription experiences available, with no length cap, offline privacy, speaker diarization, and a polished Modes and LLM workflow on Pro.
The two caveats are real, though. File transcription is Pro-only, so the free tier will not do it. And on Windows the offline models are slower and want a dedicated GPU, so the Mac-first design shows.
If those two things matter to you, a free tier that transcribes files and runs equally well on Mac and Windows, SnailText is the alternative to try. If you want the fuller feature set and you live on a Mac, superwhisper earns its price.
