AudioConvert

AudioConvert is a free online AI transcription tool that turns audio and video recordings into accurate, editable text. Powered by world-class speech models from providers like OpenAI, AssemblyAI, ElevenLabs, and Claude, the platform processes over 60,000 minutes of audio daily and claims up to 99% accuracy on clear recordings. It supports 30+ input formats including MP3, WAV, M4A, MP4, MOV, and AVI, and handles files up to 10 hours long, transcribing roughly one hour of audio in about two minutes. Transcripts include automatic punctuation, paragraph breaks, speaker diarization, and word-level timestamps, and can be exported as TXT, Word (DOCX), PDF, SRT, or VTT for direct use as video subtitles. The service recognizes more than 90 languages with localized accent handling. A built-in AI summary generator turns long recordings into structured notes, decisions, and action items. AudioConvert is privacy-first: files are encrypted in transit and at rest and automatically deleted within 24 hours, with no signup required and no use of customer audio to train AI models. A free plan offers 30 minutes of transcription per day, with paid tiers available for larger volumes and longer files.
