YTmp3.space is a free YouTube to MP3 and MP4 converter that runs entirely in your browser. Paste a link and it returns MP3 audio at up to 320kbps, the original M4A stream untouched, or MP4 video from 360p all the way up to 4K Ultra HD — no registration, no software, no ads.
Whether you are a music lover building an offline playlist, a content creator saving reference videos, or simply someone who wants YouTube videos available without internet — YTmp3 is built for you. Our clean, ad-light interface works perfectly on desktop, mobile, and tablet.
MP3 downloads come out at up to 320kbps, and M4A gives you the original audio exactly as YouTube stores it, with no second round of compression. Video runs from 360p up to 4K Ultra HD. Every conversion happens over secure HTTPS — fast, private and completely free.
No account needed. No daily limits. No hidden charges. Start converting YouTube videos right now — YTmp3 is always ready, always free, and always fast.
YTmp3 is the go-to YouTube to MP3 converter for users who want high-quality audio without paying a cent. Paste any YouTube link and the audio is extracted and delivered as a downloadable MP3 in seconds — up to 320kbps, depending on what the original upload contains.
Download three different videos as MP3 and you may see 128kbps on one, 192kbps on another and 320kbps on a third. That is not a fault, and it is worth understanding — because almost every other converter hides it behind a flat "320kbps" badge.
The reason is that YouTube does not store one audio file per video. It stores several, and which ones exist depends entirely on the upload:
A converter can only work from what is actually there. Feed it a 256kbps source and a 320kbps MP3 is a fair result. Feed it a 128kbps source and the encoder can still write a 320kbps file — but it will only be a bigger container around the same audio. The detail YouTube discarded at upload cannot be put back by any tool, at any bitrate, ever.
So when a site promises "320kbps guaranteed on every video", it is promising something YouTube itself does not provide. What it actually does is pad every file up to 320kbps so the number in your file properties looks right. You get a file two and a half times larger and not one extra second of audio detail.
Choose MP3 when compatibility matters — car stereos, older MP3 players, DJ software, anything with a USB port. MP3 plays on literally everything, and at up to 320kbps it is more than enough for listening on phone speakers, earbuds or in the car.
Choose M4A when you want the best audio the video actually has. M4A is the original stream copied straight out of YouTube with no re-encoding at all. It skips the conversion step entirely, so nothing is lost a second time. The bitrate number will often look smaller than a 320kbps MP3 — and the file will still sound the same or better, because it has not been through a lossy encoder twice.
Choose FLAC or WAV only if you are feeding the file into editing software. They are lossless containers, but lossless around a lossy source adds size, not quality.
Neither option can exceed the quality of the original upload — no converter can add detail that was never recorded. We would rather tell you that than sell you a number.
YTmp3 gives you full control over video quality when downloading YouTube content as MP4. Whether you need a compact 360p file for mobile or a full 4K video for your home screen, our platform delivers every resolution instantly.
Available MP4 resolution options:
A resolution only appears in the list if the creator actually uploaded the video at that quality. If a video was published in 720p, no tool on the internet can hand you a real 1080p version of it.
YTmp3 also supports YouTube 1080p downloads with no quality cap — making it one of the few completely free tools offering true Full HD and 4K video downloads without a premium subscription.
YTmp3 is fully unblocked and accessible from any browser, network, or device worldwide. No VPN required. No restrictions. Our platform runs entirely in your browser — meaning there is nothing to install, no app to download, and no settings to configure.
YTmp3 works seamlessly on:
Our responsive design automatically adapts to any screen size — giving you a smooth, consistent experience whether you are on a 4-inch phone screen or a 32-inch monitor.
YTmp3 fully supports YouTube Shorts downloading — making it one of the few all-in-one YouTube tools that handles both regular videos and Shorts in the same place. Simply copy your YouTube Shorts URL, paste it into YTmp3, select MP4, and download your Shorts video watermark-free in full quality.
This makes YTmp3 the perfect free YouTube Shorts downloader for creators who need to save, repost, or archive short-form content quickly and without any extra steps.
YTmp3 was built as a faster, cleaner, and more reliable alternative to tools like Y2Mate. Here is why users consistently prefer YTmp3:
Whether you previously used Y2Mate, ytmp3mate, or any other YouTube converter — YTmp3.space delivers a noticeably better experience from the very first conversion.
Open YouTube and find the video, Shorts, or playlist you want to download. Copy the full URL from your browser's address bar, or tap the Share button inside the YouTube app and copy the link. Make sure you have copied the complete URL before moving to the next step.
Go to YTmp3.space and paste the YouTube URL into the input box. Choose your preferred output format and quality:
Select MP3 if you only need the audio track. Choose MP4 if you want the full video with visuals.
Click the Download button after selecting your format. YTmp3 will process your request in seconds. Once ready, the file saves directly to your device with no redirects and no misleading pop-ups.
YTmp3 supports multiple simultaneous conversions — perfect for downloading full playlists or several videos in a single session.
Video downloads are delivered as MP4 — the one container that plays on every phone, TV, browser and editing program without a codec pack. This is the full list, and there is nothing on it that the converter cannot actually produce.

Above 720p, YouTube stores the picture and the sound as two separate files. YTmp3 merges them back together before handing you the download, which is why a 4K conversion takes a few seconds longer than a 360p one — and why the file you get actually has audio.

YTmp3 provides a complete range of resolution and quality options so you can always choose the right setting for your device, storage, and viewing preferences.
Higher resolutions deliver better image quality but produce larger files. Use this guide to pick the best option:
For music, M4A is the best choice — it is the original stream with no re-encoding, so nothing is lost twice. MP3 at up to 320kbps is the right pick when compatibility matters more, since it plays on anything with a speaker. For podcasts, lectures and voice recordings either is fine; on speech the difference is inaudible, and the smaller file is the better file.
One thing worth repeating: a higher bitrate number does not mean better sound if the source was already compressed. Judge the file by how it sounds, not by what the properties panel says.
As your YTmp3 download library grows, staying organized saves time and keeps your device running efficiently.
Review your downloads regularly and delete content you no longer need. Use cloud storage for videos you want to keep but rarely watch. Compress large video files to save space without major quality loss.
