Frequently asked questions
How do I convert a AAC file to text?
Create a free Jackob.ai account, upload the AAC file, and the AI transcribes it automatically. You can then review the transcript alongside the audio and export it as DOCX, PDF, TXT, SRT, or VTT.
What is the difference between AAC and M4A?
Same audio, different wrapper: AAC is the codec, and M4A is the file container it usually ships in. A file ending in .aac is the raw audio stream. Jackob.ai accepts both directly, so whichever your device produced, upload it as is.
Can I get the AAC transcript as a Word document, PDF, or JSON?
Yes. Every transcription exports as DOCX (opens in Microsoft Word and Google Docs), PDF for polished sharing, plain TXT, and structured JSON with timestamps and speaker labels for developers — plus SRT and VTT subtitles. All formats come from the same upload, so you never re-transcribe.
Can I try it for free?
Yes. The free plan lets you transcribe a real AAC recording each month with no credit card, so you can judge the accuracy on your own audio before paying.
Are my files kept private?
Yes. Files are processed securely, are never used to train AI models, and can be deleted from your account at any time.
