Convert any audio file to the format you actually need
Phones export M4A, meeting tools save Opus, audio editors expect WAV, podcast hosts want MP3, and old archives are full of WMA and AIFF. Vocova brings 12 audio formats together in a single page: drop in a file, pick the output, and download a clean result. No desktop install, no command-line setup, no watermark, no signup. If your audio is mostly speech, you can continue into transcription from the result screen using the same file you uploaded.
How it works
Upload your audio or video file
Drag and drop or browse. The converter accepts every common audio format produced by phones, browsers, meeting apps, podcast tools and editors, plus video files when you want to extract the soundtrack as audio.
- Audio inputs: MP3, WAV, M4A, AAC, FLAC, OGG, Opus, AIFF, WMA, AMR, AU, CAF
- Video inputs for audio extraction: MP4, MOV, MKV, WebM, AVI, WMV, FLV, M4V, 3GP, MPEG
- Up to 500 MB and 5 hours per upload
Pick your output format
Choose the format that fits the next step. MP3 and AAC for sharing and listening, M4A for Apple devices, WAV and FLAC for editing or archival, OGG and Opus for compact web audio, and AIFF, WMA, AU, CAF or MP2 for legacy workflows.
- 12 output formats covering modern and legacy use cases
- Only compatible targets are shown, so you can't pick a broken pair
- Same-format conversions are filtered out automatically
Download or send to transcription
Your converted file is ready in seconds. Download it directly, or — if the file you uploaded contains speech — continue into Vocova's transcription engine without choosing it again.
- One-click download of the converted file
- Start transcription from the same file you uploaded
- Files are deleted automatically 24 hours after conversion
Features
12 audio formats, every common pair
MP3, WAV, M4A, AAC, FLAC, OGG, Opus, WMA, AIFF, AU, CAF and MP2 — covering everyday consumer audio (MP3, AAC, M4A), pro editing (WAV, FLAC, AIFF), web delivery (OGG, Opus) and legacy archives (WMA, AU, CAF, MP2).
Works in your browser, nothing to install
There is no desktop app to download, no command-line tool to learn and no plugin to keep updated. Open the page, drop a file, and convert — the same flow on macOS, Windows, ChromeOS, Linux, iOS and Android.
Quality that matches the format
WAV, FLAC, AIFF, AU and CAF avoid MP3/AAC-style lossy compression; PCM outputs are exported at 16-bit / 44.1 kHz where applicable. Lossy targets use practical default bitrates — 192 kbps for MP3, M4A, AAC and WMA, and 128 kbps for Opus — so the output stays clean for speech, podcasts and casual listening.
Extract audio from any video
Upload an MP4, MOV, MKV, WebM, AVI or WMV and pick an audio output to pull out just the soundtrack. Useful for podcast guests, lecture captures, Zoom and Meet recordings, screen recordings and creator workflows where the video track isn't needed.
No watermark, no signup
The converted file is delivered cleanly — no audio sting, no overlay, no signup wall before download. Sign-in only kicks in if you choose to continue into Vocova transcription.
Built into a real speech-to-text workflow
Most audio converter visits are an intermediate step before transcribing, captioning or summarizing speech. Vocova keeps the next step one click away by reusing the file you uploaded, instead of making you select it again.
Why choose Vocova
Standardize messy recordings
Voice memos, exported calls, podcast clips and old archives often arrive in mixed formats. Convert everything to a single output (usually MP3 or WAV) before sharing, editing or transcribing.
Trade size for quality on demand
Pick MP3, M4A, AAC, OGG or Opus when you need a small file for sharing, streaming or storage. Pick WAV, FLAC, AIFF or AU when you need lossless quality for editing, mastering or archival.
Pull audio out of video without an editor
Extract the soundtrack from MP4, MOV, MKV or WebM in one step. No need to open Premiere, DaVinci or Audacity just to grab the audio.
Skip the second upload before transcription
If the file is going to text anyway, continue from the result screen into Vocova's transcription flow. The same file is reused, so you don't have to select it again.

Convert lectures, language practice files and study recordings into a format that plays everywhere, then turn them into searchable transcripts.
