Why On-Device Extraction Beats Cloud Converters
Traditional cloud converter websites (like FreeConvert or CloudConvert) require you to upload your video file across the internet before their servers can touch it. Here is how ExtractAudioLocal compares on real-world files:
| Video File | Cloud Converter (Upload + Wait) | ExtractAudioLocal (On-Device) |
|---|---|---|
| 3-min 1080p Clip (200MB) | ~3 to 5 minutes | 2 to 5 seconds |
| 10-min 4K Phone Video (700MB) | ~10 to 12 minutes | 5 to 15 seconds |
| 60-min Lecture / Zoom (1.2GB) | ~15 to 25 minutes | 1 to 2 minutes (or 5s M4A) |
| File Privacy & Safety | File stored on cloud servers | 100% On-Device (Zero Uploads) |
| File Size Restrictions | Paywalls after 100MB–1GB | No File Size Limits (2GB+ OK) |
