Format Factory is a browser-based workbench for batch audio and video conversion. Convert, compress, merge, or extract media in bulk with shared output and quality settings. It supports common formats including MP4, MOV, MKV, WEBM, AVI, MP3, WAV, AAC, M4A, OGG, and FLAC. Each queue shows progress, errors, retries, and downloads, while credits are transparent and results remain temporary.
