What is an AIFF file?

AIFF (Audio Interchange File Format) is Apple's uncompressed, lossless audio format, the Mac counterpart to WAV. It shows up in studio sessions, GarageBand and Logic exports, and older Mac recordings. Files are large, which makes uploading them to a web tool slow and sometimes impossible.

How to convert AIFF to text

SnailText turns a AIFF into text locally, in four steps:

Open the Transcribe files screen in SnailText.
Drop in your AIFF file, or a whole folder of them.
Pick your output: plain text, Markdown, JSON, or SRT / VTT subtitles.
Run it. The transcript is saved next to your files or wherever you choose.

The Whisper speech model transcribes on your own machine, so the audio never leaves your computer and there is no per-minute charge. AIFF is a audio format, so SnailText uses a codec pack it downloads once inside the app. After that one-time download it works offline, and transcription runs fully on your machine.

You have AIFF recordings from a studio session or a Mac app, and you want transcripts of the spoken parts. Because AIFF files are large and lossless, a local tool is the practical choice, there is nothing to upload. SnailText reads AIFF and transcribes it on your machine.

Free AIFF to text converter, no upload

Most "aiff to text online" tools upload your file to a server and cap you at a few minutes unless you pay. SnailText is the opposite: it transcribes AIFF on your device, so nothing is uploaded, there is no length limit beyond your own memory, and the free tier has no per-minute meter. That makes it a fit for anything sensitive, recordings with names, client audio, or private notes, where sending the file to a web service is the thing you want to avoid.

AIFF to text: transcript, subtitles, and more

AIFF transcription is not just plain text. Pick your output before the run and SnailText writes any of these:

· Plain text (TXT) for a clean transcript you can read, search, and edit.
· SRT and VTT subtitles with phrase-level timestamps, ready to drop onto a video.
· Markdown with a heading per file, handy for notes and docs.
· JSON for feeding the transcript into your own scripts or tools.

AIFF to text FAQ

Can I transcribe an AIFF file?

Yes. SnailText handles AIFF through its codec pack (a one-time download), then transcribes it locally with the Whisper model. AIFF files are large because they are lossless, so a local tool with nothing to upload is the practical way to transcribe them.

Does AIFF give better transcription than a compressed format?

AIFF is lossless, so the model gets the full audio, but for speech a good compressed file usually transcribes about the same. The benefit of AIFF is quality-preserving storage. If your recordings are already AIFF, SnailText transcribes them with no conversion.

Is AIFF transcription free?

SnailText's free tier transcribes locally with the compact Whisper models, no account and no per-minute meter. Pro adds the larger, more accurate models and an optional on-device AI cleanup pass, $7.49/mo or $89/yr for up to 3 devices.

Can I transcribe a whole folder at once?

Yes. Drop a folder (or several files) into the Transcribe files screen and SnailText processes them one after another, writing a transcript for each. It scans the files directly in the folder. You can also drag and drop files straight in.

Can I get SRT or VTT subtitles?

Yes. Pick SRT or VTT as the output before you run the transcription and SnailText writes a subtitle file with phrase-level timestamps. Choose it up front, since subtitles are produced during the run. You can also export plain text, Markdown, or JSON.

What languages can it transcribe?

SnailText transcribes in the full set of Whisper languages (99), and can auto-detect the language or let you pick. Everything runs locally, so multilingual transcription works with no internet after the model is downloaded.
