YouTube to MP3 Estimator

About This Tool

This tool estimates the MP3 file size for a YouTube video based on duration and encoding bitrate. It is designed for planning storage, bandwidth, and licensing considerations without downloading or encoding any media.
You provide a YouTube URL, the video duration in seconds, and a target bitrate in kbps. The tool applies a simple arithmetic calculation to estimate file size and offers a range of common bitrates for quick comparison.
Outputs include an estimated file size in MB and the expected download time at that bitrate, helping users plan budgets, storage, and policy compliance. The core logic is numeric and metadata-driven: no media processing occurs on the client side, and no files are transferred.
Who benefits: content creators, podcasters, educators, researchers, and teams performing offline planning or licensing reviews. Unique value lies in combining URL-aware input with transparent, math-based size estimates suitable for budgeting and compliance checks.
