QUICK ANSWER
What does the YouTube audio downloader return?
This page lists audio-only formats exposed for the source video, typically M4A/AAC or WebM/OPUS. Because these are original streams rather than MP3 conversions, the listed codec and bitrate reflect what is available for that video.Service limits were verified from the deployed YouTube Shorts Downloader configuration on August 31, 2026. The public resolver accepts three individual YouTube URL types, keeps metadata and temporary source links in memory for 120 seconds, and stops a resolver request after 35 seconds. Output jobs are limited to videos of 20 minutes or less and two simultaneous jobs. These first-party limits apply to the current service and may be revised when server capacity changes.
