Guides
Know your audio, pick with confidence.
Short, practical guides to the choices you make when you extract audio from a video: which format, which bitrate, what you're allowed to convert and what to do when something goes wrong.
All guides
Five short reads. Each one takes less than ten minutes.
MP3, M4A, OPUS, WAV or FLAC? How to choose an audio format
A plain-English comparison of MP3, M4A, OPUS, WAV and FLAC: sound quality, file size, compatibility and which one to pick for music, podcasts and editing.
128, 192 or 320 kbps? Choosing the right MP3 bitrate
What MP3 bitrate actually means, how much space each setting uses, and why 320 kbps can't make a low-quality upload sound better.
Extracting audio for video editing, podcasts and transcription
How to pull clean audio out of a video for editing timelines, podcast episodes, transcription and study notes, and which settings to use.
Can I convert this video? Copyright basics for audio extraction
A practical overview of when it's fine to save a video's audio: your own uploads, public domain, Creative Commons and permission, plus what to avoid.
Why did my conversion fail? Common errors and how to fix them
Every message Konvert can show, what causes it and what to try next: private and restricted videos, playlists, length limits and more.
Where to start
Three questions, three answers
Most people only need one of these. Start with the question that sounds like yours.
“Which format should I choose?”
MP3 plays everywhere. M4A suits Apple devices, OPUS keeps files small, and WAV or FLAC are for editing. The formats guide explains the trade-offs and what really happens to the sound.
“Is 320 kbps worth it?”
Higher bitrates mean bigger files, but they can't add detail the video never had. See exactly how much space each MP3 setting uses and how to test the difference yourself.
“Why didn't it work?”
Private, restricted and removed videos can't be converted, and playlists aren't supported. The troubleshooting guide walks through every message and what to try next.
About these guides
Every guide is written to be useful on its own, whether or not you ever use Konvert. Where we describe how the converter behaves, such as when audio is copied as-is and when it's re-encoded, we've checked it against the software the service actually runs, not a spec sheet.
We keep them short and specific. You'll find real numbers you can check (like how many megabytes a minute of audio takes at each bitrate), honest limits (a higher setting can't restore quality the upload never had) and clear advice on using audio responsibly. If you just want to get started, the step-by-step how-to and the FAQ cover the basics in a couple of minutes.
