FFmpeg Batch AV Converter vs Free YouTube to MP3 Converter

FFmpeg Batch AV Converter is a graphical interface for using FFmpeg's command-line capabilities in audio and video workflows. It supports unlimited single-file or multi-file batch encoding for formats handled by FFmpeg, including MP3, AAC, AC3, FLAC, WAV, Opus, and Vorbis. Encoding options include simultaneous jobs, two-pass processing, fixed output target size, and custom parameters that can be created with an encoding wizard. Users can drag and drop files, track progress, change priority, pause or resume, and set automatic shutdown or folder monitoring. The application also supports stream mapping, multiplexing, demuxing, subtitle processing, trimming, concatenation, thumbnail extraction, image-to-video creation, silence detection, splitting, and chapter creation. It can batch-download YouTube videos, live events, and m3u8 links through a youtube-dl/yt-dlp interface for supported URLs. The free, open-source project has been developed since 2017 under LGPL-2.1. Windows and Linux are supported; Linux use requires Wine 9.0 or higher and wine-mono.

Free YouTube to MP3 Converter downloads YouTube audio streams and saves them in MP3, AAC, M4A, OGG, FLAC, or WAV; it can also keep the original stream without converting it. MP3 choices include Lame Insane, Extreme, and Standard presets, including 320 kbps files. The application can process bulk downloads, including entire playlists and channels, and its free version has no daily limit on batch downloads. It can merge audio, customize output names, and fill MP3 tags and artwork automatically. Downloaded music can be transferred directly to iTunes playlists. The application is listed for Android, macOS, and Windows, and includes quality controls and metadata editing. Digital Wave says its applications do not collect personal information, while its website privacy policy describes account, contact, purchase, and cookie data it may collect. The maker describes the software as clean and safe; that is the maker's own claim. Its FAQ discusses a 105403 forbidden error that can follow YouTube configuration changes and recommends updating the application.
