4K YouTube to MP3 26.3.5 on Mac

Open the Format tab before you grab anything. That's where the real control lives.

MP3 — the default. Broadest player support, decent size. For podcasts and voice this is usually enough.

M4A — better quality per megabyte than MP3, especially for music. If you're archiving a 4K in YouTube mix, this keeps the detail without bloating the folder.

OGG — the pick for open-source players and some DJ software. Less portable, but fine if your workflow lives outside Apple's ecosystem.

Version 26.3.5 runs on macOS 12 and newer, but only on Intel Macs. So if you're on an M-series machine, you'll need to run it under Rosetta. The interface stays English throughout.

Playlist or single track download

A few questions come up often enough that they're worth answering before you download.

Does it download the whole playlist or just one track?
It handles both. Paste a single video link and you get one audio file. Paste a playlist URL and the app pulls every track in it, one after another. Useful if you're grabbing a whole album or a DJ set someone split into parts.

Will it keep the metadata — artist, title, album?
Yes, mostly. The app reads whatever tags are embedded in the source. YouTube and SoundCloud don't always supply clean metadata, so you might need to edit a few tags yourself after the download. But the title and uploader name usually come through correctly.

Can I choose the bitrate?
Not directly in the version described here. The app picks a sensible bitrate based on the source quality and the format you selected. For most listening purposes — car, gym, phone — it's fine. If you're after archival-grade audio, you'd want the highest available source anyway.

Is it legal to use?
That depends on what you download and where. The app itself is a tool. Downloading copyrighted music without permission is against terms of service in most cases. Public domain content, your own uploads, or Creative Commons material is fine. Use it sensibly.

Best for commuters and weak-signal areas

This app suits a few specific types of Mac owners more than others.

• Commuters with limited data plans. Streaming music on a mobile connection eats through your allowance fast.
• People in areas with patchy internet. If your train route or local café has dead zones, offline audio means no interruptions. Grab a few hours of podcasts or music before you head out.
• DJs and radio producers working offline. Preparing a set? Downloading tracks from SoundCloud or YouTube lets you audition and organise them without an active connection during the gig.
• Anyone building a local music library. Streaming services remove songs without warning. A local MP3 or M4A collection stays yours. This app makes it quick to back up tracks you care about.

If you fall into one of these groups, the time you spend setting up the app once pays back quickly.

Podcast editor grabbing clips on shaky Wi-Fi

Consider a podcast editor working from a shared studio. The studio Mac has limited storage and the Wi-Fi drops every hour or so. She needs to grab reference tracks, sound effects, and interview clips from YouTube and SoundCloud, then bring them into her editing software.

With 4K YouTube to MP3, she pastes a playlist of interview segments before leaving home. By the time she arrives, all the audio is saved as M4A files — better quality than MP3 for the speech detail she needs. She drags them straight into her editing timeline. No buffering, no re-downloading. The OGG format isn't useful here because her editor prefers M4A, but the choice is there if she switches tools later.

The same workflow works for a music student building a sample library for a composition project. Pulling stems, loops, or full tracks from video sources and converting them to MP3 for quick playback on any device.

Set a dedicated download folder first

Once the app is in your Applications folder, a few habits make it more useful from the start.

• Set your download folder before you start. The app saves files wherever you point it. Create a dedicated folder inside Music or Documents so you're not hunting through your desktop later.
• Check the format before you paste a long playlist. Changing it mid-way means inconsistent files. Pick MP3 for maximum portability or M4A for better quality per megabyte, then stick with it for that session.
• Paste one link first to test. If you're downloading a 4K music video source, convert a single track and listen to the result. If the quality sounds fine, proceed with the full playlist. Saves time if the source turns out to be poor.
• Rename files early. The app uses the video title as the filename, which can be long or messy. Rename them right after download while the source is still fresh in your mind.
• Keep a text file of playlist URLs. If you're a regular user, paste the link into a notes document before converting. That way you can re-download a track later if you lose the file, without searching YouTube again.
