LuminaAudio Audio Converter vs Media.io Audio Converter

LuminaAudio Audio Converter is a free browser tool for converting audio among MP3, WAV, and AAC. It supports MP3-to-WAV, MP3-to-AAC, WAV-to-MP3, WAV-to-AAC, AAC-to-MP3, and AAC-to-WAV conversions. M4A files are accepted as AAC input. The FAQ also describes extracting audio from MP4, MOV, MKV, and WebM video files and saving it in a selected format. Conversion runs locally in the browser through the Web Audio API; during normal use, files are not uploaded to LuminaAudio servers. WAV output is lossless PCM, while MP3 and AAC outputs are compressed. All six conversion paths are listed as free, with no sign-up, watermarks, or stated hidden limits. The tool runs in modern Chrome, Firefox, Safari, and Edge on Windows, macOS, Linux, Android, and iOS. LuminaAudio names TikTok creators, music producers, lo-fi enthusiasts, and people who want to reimagine music as its audience. Google Analytics may process visits, approximate location, device and browser information, referral source, and general usage activity. Email support covers technical, feature, partnership, press, copyright, privacy, and general questions; most emails receive a reply within one business day. The Free plan is free.

Media.io Audio Converter turns audio files into formats such as MP3, WAV, OGG, M4A, and AAC. Users upload a file, choose an output format, convert it, then download the result. The listed format support also includes MP2, WMA, FLAC, M4B, M4R, AC3, APE, AIFF, and AMR. It handles individual files and batches; the product page says most conversions finish in under 10 seconds. The browser tool works in Chrome, Safari, Firefox, and mobile browsers without installation, and the listed platforms are web, Android, and iOS. An account can save conversion history for access across devices. Media.io says users keep ownership of source and converted files, while uploads and generated content are deleted from its servers within seven days and are not backed up. The service has a free plan and a three-day trial. The free trial allows up to one audio generation; paid-plan prices are displayed as unresolved templates, so no numeric amount is available.
