How do I convert an OPUS voice note to text?
To convert an OPUS file to text, upload the .opus voice note to Pepys and it transcribes the audio into a clean, timestamped transcript in minutes, in 99+ languages, with an AI summary built in. It's ideal for WhatsApp voice notes you'd rather read than replay. Your first 60 minutes are free, no card required.
How opus to text works
Save the voice note
Export or save the .opus file – for a WhatsApp note, tap the message and share or save the audio.
Upload it to Pepys
Drop the .opus file in and AI transcribes the speech into clean, timestamped text in minutes.
Read and export
Read it, copy any line, ask the AI for a quick summary, or export to TXT, Markdown, DOCX, PDF, or SRT.
OPUS is the format messaging apps use for voice notes – WhatsApp, Telegram, Signal all save them as .opus. They're tiny and efficient, but you can't skim a two-minute ramble or search for that one address someone rattled off. Pepys turns the .opus file into accurate text in minutes, so you can read it instead of replaying it three times.
Upload the voice note and you get timestamps plus an AI summary, so a long message collapses into the point. It works in 99+ languages and auto-detects whichever one was spoken. Your first 60 minutes are free, you pay only for what you transcribe, credits never expire, and we never train on your audio.
Clean paragraphs. No more um's and ah's.
The left is what Pepys hands back – logical paragraphs with the filler stripped out, punctuated and readable. The right is the raw, one-line-per-segment dump most transcribers leave you with.
um so yeah everyone keeps telling you to like lead with your best line right but uh honestly if you give away the whole answer in the first second you know there's basically no reason for anyone to keep watching so the hook isn't kind of the smartest thing you say it's like a loop you open that they need to close and um that's the part that actually keeps people around
