Convert MP3 to a PDF
Upload an MP3 file and ScreenApp turns the spoken words into a PDF document with speaker labels and timestamps. There is no separate transcription step to sit through: upload the file, and the PDF comes out the other end, ready to read, search, or print.
A PDF is easier to work with than the raw audio: search it with Ctrl+F, print it, or attach it to an email without asking anyone to sit through the recording.
What you get:
- A transcript with speaker labels and timestamps, in 99 languages
- Export as PDF, DOCX, TXT, SRT and VTT
- AI notes: a summary and the main points from the recording
- Ask AI questions about the recording and get answers that point to the moment it happened
- Free plan: one recording of up to 45 minutes, with AI chat on it
Here is a sample of what the PDF looks like before you upload anything of your own. This one came from a 32-minute MP3 podcast: section headings picked up from topic shifts, key points organized as bullets, structured notes instead of a wall of unbroken transcript text.
Need a Word document instead of a PDF? The same upload works on the audio to Word converter.
How to Convert MP3 to PDF
- Upload your MP3 file: Drag in an MP3, WAV, M4A, or other supported file, or paste a link to an audio source. The file imports into your ScreenApp library, so you need an account: Yes, free (no card).
- Let it transcribe: The audio converts to text, speakers are separated, and punctuation and paragraph breaks are added automatically.
- Download the PDF: Open it on any device, search it, print it, or attach it to an email.
Accuracy depends on the audio. A clear recording with one speaker and little background noise transcribes best; a phone recording from across a noisy room will have more gaps. See how we measure accuracy.
