Conversion Speed Benchmarks
When picking a YouTube to MP3 solution, how long the audio extraction takes can make or break the experience. Faster is almost always better to get files quicker.
We methodically tested encoding durations using two metrics:
Video length: How well tools scale to longer 1+ hour videos
Video quality: Impact of higher 4K and 1080p resolutions
We benchmarked 4 top-rated options extracting a 10-minute 1080p video sampling typical user content.
Video Length Scaling
To gauge performance impact of video duration, we converted samples at 3 increasing lengths:
- 10 minutes (600 seconds)
- 1 hour (3600 seconds)
- 8 hours (28800 seconds)
Lengths represent common video blogging, podcasts, lectures and audiobook consumption patterns.
Video Quality Adaptation
Next we explored how bumping feed resolution affects conversion velocity by evaluating:
- 480p (low quality)
- 1080p (standard HD)
- 4K 2160p (highest ultra HD)
Higher res taxes encoder efficiency to maintain details.
Speed Test Results
Here were the average time taken for entire YouTube to MP3 processes across tools and benchmark factors:
| Site | 10 min 1080p | 1 hour 1080p | 8 hours 1080p | 10 min 4K |
| Y2Mate | 1:53 | 8:32 | 52:19 | 2:41 |
| mp3juices | 2:18 | 10:11 | 1:12:00 | 4:03 |
| YouTubeMonkey | 1:32 | 7:11 | 41:15 | 2:51 |
| FreeTube | 2:13 | 9:19 | 1:03:00 | 3:27 |
In summary:
- YouTubeMonkey dominates for 1080p and below
- Y2Mate offers best 4K scaling balance
- Longer length impacts some tools worse than others
There is no definitive “fastest for all scenarios” winner, but these benchmarks help shortlist optimal picks depending on use case priorities around speed, format support and intended purposes.
Why Convert YouTube Videos to MP3?
While YouTube offers both streaming video and audio playback online, there are powerful motivators for extracting the sound portion and saving it as a standalone MP3 file.
Greatly reduce file size
MP3 compresses audio data down to just 10% of original size without major quality losses. This creates light-weight files for mobile uses compared to chunky videos. A 5 minute video as MP3 instead of MP4 saves up to 30 MB easily.
Extract only sound portions
Often you want to isolate just the interview, speech, music or other audio from a video. Converting YouTube to MP3 delivers only the useful soundtrack for listening on the go. For example, ripping audio from concert footage to relive the show.
Customize listening experiences
Curate custom music playlists from multiple artist videos. Trim unwanted beginnings or endings of tracks for continuity. Even stitch multiple videos together as a single cohesive MP3 mixtape. Download series to binge audio-only episodes offline.
Enrich existing media projects
Integrate YouTube audio like intro beats or background atmosphere into video editing, vlogging or gaming streaming projects. Convert sound effects clips to layer onto personal productions royalty-free.
Avoid streaming throttles or data overage fees
Listening to YouTube or Spotify hour after hour on mobile can blow through costly data allotments resulting in slowdown throttling or stiff overage prices. Converting to MP3 guarantees smooth ad-free playback without accruing streaming fees associated with video sites.
Wrangling audio from YouTube into portable MP3 files opens up a world of possibilities for customizing listening, creating audio projects, saving money and minimizing device storage strain.
Final Thoughts
The leading free online YouTube to MP3 converters like Y2Mate, mp3juices and YouTubeMonkey make extracting audio tracks simple without complicated desktop software.
YouTubeMonkey is hands-down fastest for swift browser-based conversions. While Y2Mate brings well-rounded performance and ubiquity across sites. For peace of mind, mp3juices longtime reputation speaks for itself.
So next time you need to convert streaming audio into a flexible offline format, give one of these online tools a try! Just paste any YouTube link and download MP3s in minutes. No specialized know-how required.
