How to convert audio and transcripts to a PDF
Drop an audio file, a transcript file (.vtt, .srt or .txt), or both onto the box above, choose A4 or US Letter paper, and select Create transcript PDF.
Download a clean, multi-page PDF with an audio summary header and timestamped transcript cues.
What the PDF includes
When you include an audio file, the PDF header records the recording's format, duration, sample rate, channels and level summary; for WAV files it also segments spoken intervals from the waveform.
When you include a .vtt, .srt or .txt transcript (or pair it with the audio file), every cue is laid out with its start–end timestamp and wrapped cleanly across numbered pages.
Your recording never leaves your device
Audio header inspection and PDF typesetting happen in your browser with pdf-lib. No recording, transcript or file name is ever uploaded.
