YT2MP3 - YouTube to MP3
Save YouTube videos as MP4 in seconds
MP4 is the universally-compatible container for H.264 video and AAC audio — it plays on every phone, tablet, TV, and video editor. yt2mp3.lol pulls the highest-quality MP4 streams YouTube serves, merges them with FFmpeg, and hands you a single file that's ready for offline viewing, archiving, or editing.
Available resolutions
We always select the best track that matches your chosen height. 360p and 720p are the safest bet for small phones and slow connections. 1080p is the sweet spot for laptops and TVs. 1440p and 2160p (4K) are exported when the original video was uploaded at those resolutions.
How to download YouTube as MP4
Copy the video URL from YouTube's share menu or your browser address bar, paste it into the converter, select MP4 and your preferred resolution, then click Convert. A three-minute 1080p clip typically takes under 10 seconds.
Shorts and live replays
Shorts export in their native vertical aspect ratio. Live stream replays (VODs) work once YouTube has finished processing them, usually within minutes of the stream ending.

High-Definition MP4 Downloads
Unlike converters that compress your files to save bandwidth, our tool fetches the highest available MP4 quality directly from YouTube's servers. Whether the original upload is in 720p, 1080p, 1440p (QHD), or 2160p (4K), you receive an uncompromised H.264 video file paired with AAC audio for universal compatibility.
Why MP4 is the Best Format
MP4 is the industry standard for digital video. It offers an exceptional balance between file size and video quality. Most importantly, MP4 files play natively on every modern device—from iPhones and Android smartphones to Smart TVs, PlayStation, Xbox, and all major video editing software like Premiere Pro and Final Cut.
Bypass Buffering for Offline Viewing
Internet connections can be unreliable, and YouTube ads can ruin the viewing experience. By converting your favorite documentaries, tutorials, or music videos to MP4, you guarantee uninterrupted, ad-free playback during flights, commutes, or in areas with poor cellular reception.
Hardware-Accelerated FFmpeg Processing
Behind the scenes, we utilize clustered servers running hardware-accelerated FFmpeg. This means that when we mux the separate high-resolution video and audio tracks from YouTube into a single MP4, the process takes seconds rather than minutes. You get your file almost instantly.
No Watermarks or Time Limits
Many free tools slap a huge watermark on your video or limit you to 5-minute clips. We believe in providing a premium experience for free. You can download 3-hour long podcasts or full-length public domain movies in MP4 format with absolutely zero watermarks.
Safe, Secure, and Private
We respect your digital privacy. Our MP4 converter runs entirely in your browser through secure API calls. We don't require you to install sketchy browser extensions, we don't ask for your email address, and we automatically purge your converted files from our cache within 30 minutes.
Compatible with All Browsers
Whether you are a power user on Chrome, a privacy advocate using Brave or Firefox, or browsing on Safari on your iPad, our web-based tool functions flawlessly. No need to worry about OS compatibility or downloading separate desktop apps.
Perfect for Content Creators
If you need B-roll footage, stock videos, or meme templates, our MP4 downloader provides the raw files you need to import directly into your timeline. The standard H.264 codec ensures you won't need to transcode the footage before editing.

FAQ
What is the highest MP4 quality you support?
2160p (4K) when the source offers it. Falls back to the best available height otherwise.
Does the MP4 include audio?
Yes. Video and audio tracks are merged into a single MP4 with H.264 video and AAC audio.
Is the MP4 watermark-free?
Yes. No watermarks, overlays, or trailers are added to the file.
Is downloading MP4s from YouTube legal?
You should only download content that you own, have permission to use, or that is licensed under Creative Commons or is in the public domain. Please respect copyright laws in your jurisdiction.
Why isn't 4K available for all videos?
Our tool can only provide resolutions that were originally uploaded by the creator. If a video was filmed and uploaded in 1080p, a 4K option will not exist.
Does the downloaded MP4 have sound?
Yes! While YouTube stores high-res video and audio separately, our FFmpeg backend automatically merges (muxes) the video and audio tracks so you get a complete, playable MP4 file.
How long does the conversion take?
For standard 1080p videos under 10 minutes, conversion usually takes 5-15 seconds. Longer videos (e.g., 2 hours) or 4K files will take proportionally longer due to file size.
Can I download MP4s on my iPhone?
Yes. You can use Safari on iOS to access our site. Once converted, tap 'Download' and Safari will save the MP4 directly into your Files app or Photos app.
Is there a limit on file size or length?
We currently support videos up to 3 hours in length to ensure our servers remain fast and stable for all users. There are no daily usage limits.
Do I need to install any software?
No. Everything is handled cloud-side. You do not need to install any desktop software, mobile apps, or browser extensions.
Why did my download fail midway?
This usually happens due to a network interruption on your end, or if the video is suddenly made private or age-restricted. Simply refresh the page and try again.
Are there any viruses or malware?
Our service is 100% clean. We do not inject ads into the video, and we do not use deceptive download buttons. You receive the pure video file.
Can I convert a playlist to MP4?
Yes, we support playlist conversions. Simply paste the playlist URL, and you can queue up all the videos to be downloaded as separate MP4 files.
