Convert your MP3s to text. Upload the file, download the document. Translated, if you like.
MP3 is the most widespread audio format in the world: recorders, podcasts, old archives, exports from any software. Verlio turns it into a tidy document, with speakers identified and export to Word, PDF, SRT and VTT.
How it works — in 3 steps.
Upload the MP3 file to Verlio from your browser: no software to install, no preliminary conversion, files up to 6 hours and beyond.
Choose the language of the final document — even different from the audio's, translation across 35+ languages is included — and enable AI cleanup and speaker recognition.
Download the text as Word or PDF, or as SRT/VTT if the MP3 is a video's audio track and you need subtitles.
How to convert an MP3 to text for free?
Every day you get 10 free minutes on Verlio: upload, transcribe, download, without entering a card. At signup you also receive 30 minutes of free trial — useful for testing the service on a long file: an interview, a podcast episode, a lecture.
Beyond the free minutes, credits start at €5 and one credit covers 1 minute of audio, so you pay only for what you transcribe. No monthly subscription: you buy credits when you need them, use them whenever you want, and they never expire.
Why MP3 is everywhere (and why quality matters).
MP3 is the universal format of digital audio: voice recorders, recording apps, podcast platforms, editing software and decades of archives all produce it. It's lossy-compressed, so a one-hour file weighs a few dozen MB — perfect for uploading even on slow connections.
Compression cuts information, though: with very low-bitrate MP3s (old or heavily compressed recordings), a weak transcription engine degrades noticeably. Verlio uses state-of-the-art speech recognition models that hold up well even with compressed audio, overlapping voices and background noise; for technical topics, the context document helps the AI with names and specialist terminology.
What you get beyond the raw text.
The difference between a transcript and a useful document is structure. With Verlio's Structured Document, the MP3 becomes a file with an opening summary, key points, thematic sections and a glossary of terms: ready to archive, share or quote. If several people speak in the file, every contribution is attributed to the right speaker. Everything is processed on servers in the European Union, in compliance with the GDPR.
Frequently asked questions.
How much does it cost to convert a one-hour MP3 to text?
You pay only for the minutes you use (1 credit = 1 minute), with packs from €5 and credits that never expire. Your first hour is covered by the free trial at signup, no card.
Is there a length or size limit for the MP3 file?
Verlio handles files over 6 hours. For very long recordings — conferences, hearings, full working days — there's no need to split the file.
The MP3 is in another language: can I get the text in English?
Yes. Choose English as the document language and Verlio transcribes and translates in a single pass. It works with 35+ languages, in both directions.
Does the transcript tell speakers apart?
Yes, speaker recognition attributes every line to the right voice: essential for interviews, meetings and roundtables recorded as MP3.
Which formats can I export the text in?
Word and PDF for documents, SRT and VTT for subtitles. You can also copy the text directly from the online editor.
