Frequently Asked Questions About Audio to PDF
Will my PDF file be uploaded to a server?
This tool sends some data to a server to work: Your audio file is sent to a server-side transcription service to turn speech into text — running full transcription in the browser would require downloading very large AI models.
Is there a file-size limit, a usage cap, or a hidden fee?
This tool runs server-side, so it enforces its own limits (a file-size cap and, in some cases, a daily quota) — see this tool's own page for the exact numbers.
Do I need to create an account or sign up?
No — no account, email, or sign-up is required for any tool. Just start using it.
Can I use this on my phone (iPhone or Android)?
Yes — it works in any modern mobile browser, no app install needed.
What languages does this tool support?
A very wide range — the transcription doesn't require picking a language, it detects and transcribes accurately from the recording itself. There's no separate language selector.
Is there a file size limit?
Yes, audio files up to 10 MB per upload — enough for a typical voice memo or several minutes of recording.
What can I do to improve transcription accuracy from my recording?
Use recordings with clear speech and minimal background noise, and boost the audio volume beforehand if speakers are quiet.
Is the resulting PDF transcript searchable?
Yes. It creates a genuine PDF document with text formatted into paragraphs that you can search with Ctrl+F or highlight.
