Free Online WebM to MP3 Converter
Convert WebM to MP3 — Get Audio from Browser Videos, Downloads, and Clips
Ended up with a .webm file and not sure what to do with it? You are not alone. WebM is the format your browser quietly uses behind the scenes for web video, and it shows up in the most unexpected places: when you right-click and "Save Video As" from a website, when yt-dlp or gallery-dl finishes a download, when someone sends you a clip on Discord, or when a screen recording extension saves your capture. The problem is that WebM does not play nicely outside of browsers. Your phone's music app, your car stereo, and most media players either struggle with it or refuse to open it entirely. This WebM to MP3 converter fixes that. Drop in any .webm file — whether it has VP8/Vorbis audio, VP9/Opus audio, or even an audio-only WebM stream — and get a standard MP3 that works everywhere. Everything runs locally in your browser with nothing uploaded to any server.

Where Do WebM Files Come From?
WebM is Google's open video format, built for the web. It is everywhere online, even if you do not always realize it. Here are the most common ways people end up with .webm files they want to convert to MP3.
Downloads from yt-dlp and Browser Extensions
Tools like yt-dlp, youtube-dl, and gallery-dl often save video as WebM because that is the native format served by many websites. If your download folder is full of .webm files and you just want the audio, converting WebM to MP3 gives you music, podcasts, and audio clips in a format your phone can actually play.
Clips from Discord, Reddit, and 4chan
People share WebM clips constantly on Discord servers, Reddit threads, and imageboards. When you save one of these clips, you get a .webm file that might not play on your device without a special app. Change that WebM to MP3 and you have the audio — a funny sound bite, a music clip, a voice message — in a universal format.
Screen Recordings from Browser Extensions
Extensions like Screencastify, Loom's browser recorder, and other screen capture tools often save recordings as WebM. If you recorded a meeting, a tutorial walkthrough, or a webinar and you only need the spoken audio for notes or a podcast, converting WebM to MP3 strips out the screen footage and leaves you with a clean audio file.
Why This WebM to MP3 Converter Works When Others Don't
WebM is a format that most desktop software was never built to handle well. Even media players that technically support it often stumble on certain codec combinations. Here is what this converter actually does right.
Handles Both VP8/Vorbis and VP9/Opus Variants
WebM files come in two main flavors: older VP8 video with Vorbis audio, and newer VP9 video with Opus audio. Some converters only handle one type. This WebM to MP3 converter reads both variants and decodes whichever audio codec is inside — Vorbis or Opus — then re-encodes it as a standard MP3 file.
Converts yt-dlp and gallery-dl Downloads Instantly
If you use yt-dlp or gallery-dl, you know the drill: you end up with a pile of .webm files in your downloads folder. Drop them into this converter and get MP3s back in seconds. It handles the exact WebM format these tools produce, including the audio-only streams that yt-dlp sometimes saves when you request audio formats.
Works with Discord, Reddit, and 4chan Clips
WebM is the native sharing format on many online communities. Clips saved from Discord channels, Reddit video posts, and imageboard threads convert to MP3 without any issues. The converter reads these short-form WebM clips just as easily as long recordings — no minimum or maximum duration.
Processes Screen Recording WebM Files
Browser-based screen recorders like Screencastify export WebM by default. Whether you recorded a 5-minute demo or a 2-hour webinar, this converter pulls the audio out and gives you an MP3. Great for turning screen captures into podcast segments or meeting notes you can listen to later.
Reads WebM Files That Other Players Refuse to Open
Windows Media Player does not play WebM. QuickTime does not play WebM. Many Android gallery apps choke on WebM files. If you have a WebM that will not open in anything on your device, this converter can still read it and extract the audio to MP3. It uses the same decoding engine as modern browsers, so if Chrome can play it, this tool can convert it.
Audio-Only WebM? Converts Those Too
Not every WebM file contains video. Some are audio-only containers holding Opus or Vorbis streams — this is common with yt-dlp audio downloads and web audio captures. This converter handles audio-only WebM files just fine. Drop it in, get your MP3 out. No video track required.
How to Convert WebM to MP3 — Three Quick Steps
The whole process works the same whether your WebM is a 10-second Discord clip or a 3-hour stream recording.
Add Your WebM File
Open videotoaudio.net in any browser. Drag your .webm file onto the page or tap the upload area to select it from your downloads. Got a batch of WebM files from yt-dlp or a Discord archive? Drop them all in at once.
Choose Your MP3 Quality
MP3 is already selected as the output format. Pick a bitrate: 128 kbps keeps things small and works well for voice clips and spoken content, 192 kbps is a strong choice for music, and 320 kbps gives you the best quality MP3 can offer — ideal if the original WebM had high-quality Opus audio.
Download Your MP3
Tap convert and your MP3 is ready in seconds — WebM files tend to be small, so conversion is fast. Save individual files or download the whole batch as a ZIP. That is it — your WebM to MP3 conversion is complete and the files are ready to play on any device.

WebM to MP3 — Frequently Asked Questions
Why did my browser save a video as .webm instead of .mp4?
Many websites serve video in WebM format because it is open-source and compresses well. When you right-click a video and choose "Save Video As" in Chrome or Firefox, the browser saves it in whatever format the site was actually streaming. If the site was using WebM (which is very common on modern websites), that is what you get. It is not a bug — it is just the format the video was already in.
Can I convert WebM files downloaded with yt-dlp or youtube-dl?
Yes, this is one of the most common use cases. yt-dlp often downloads video in WebM format because many sites serve VP9/Opus as their highest quality stream. Drop those WebM files into this converter and you get clean MP3s. This also works for audio-only WebM files that yt-dlp creates when you use format selection to grab just the audio stream.
My WebM file plays audio but has no video — can I still convert to MP3?
Absolutely. Audio-only WebM files are totally valid — they are just Opus or Vorbis audio wrapped in a WebM container. This WebM to MP3 converter handles them perfectly. You will get an MP3 with exactly the same audio content, just in a format that every device and music player can actually open.
Why doesn't Windows Media Player play WebM files?
Microsoft never built WebM support into Windows Media Player because WebM is a Google-backed format. Windows Media Player expects Microsoft-friendly formats like MP4, WMV, and AVI. You can install third-party codec packs to add WebM support, but honestly, it is easier to just convert WebM to MP3 if you only need the audio. One conversion and the file plays everywhere.
Can I convert a WebM screen recording to MP3 for a podcast?
That is a great use case. Screen recording extensions like Screencastify save WebM files that contain both the screen capture and your microphone audio. Converting that WebM to MP3 strips away the video and gives you just the spoken audio. It is a quick way to repurpose a recorded tutorial or meeting into audio-only content for a podcast feed or study notes.
WebM with Opus audio vs WebM with Vorbis — does it matter for conversion?
Not for you, no. Opus is the newer, more efficient codec and tends to sound better at lower bitrates. Vorbis is the older codec found in earlier WebM files. This converter reads both seamlessly. The only practical difference is that Opus WebM files might produce slightly better-sounding MP3s at the same bitrate, since the source material was encoded more efficiently. But either way, you get a perfectly good MP3.
How do I convert a WebM from Discord to MP3?
First, save the WebM clip from Discord to your device — on desktop, right-click the video and choose "Save Video." On mobile, long-press and download. Then open videotoaudio.net in your browser, drop the saved .webm file onto the page, and hit convert. Your MP3 will be ready in a few seconds. Works the same for clips from Discord bots, shared channels, or DMs.
My WebM is a long 1080p60 video — will it take forever to convert?
No. The resolution and frame rate of the video do not affect conversion time because the converter skips the video entirely and only processes the audio stream. A 1080p60 WebM and a 360p WebM with the same audio will convert to MP3 in roughly the same amount of time. The length of the audio is what matters, and even long recordings usually finish in under a minute.
Can I convert WebM files saved from Twitter/X?
Yes. When you download videos from Twitter or X using browser extensions or third-party tools, they sometimes arrive as WebM files. This converter handles them like any other WebM. Drop the file in, convert WebM to MP3, and you have the audio ready to go. Works for short tweet clips and longer Spaces recordings alike.
WebM to MP3 vs WebM to OGG — which should I choose?
Go with MP3 if you want the file to play on everything — every phone, every car stereo, every Bluetooth speaker, every app. MP3 is the most universally supported audio format in existence. Choose OGG if you are keeping things within the open-source ecosystem (Linux, Firefox, certain Android apps) and want better quality at smaller file sizes. For most people, MP3 is the right call because you will never have to think about compatibility.
