About Audio Tools

SimplyToolbox's audio tools let you handle common sound-file jobs without opening heavyweight editing software or signing up for a service. Convert recordings between popular formats such as MP3, WAV, OGG, AAC and FLAC so they play on any device. Trim and cut clips to keep only the part you need — handy for ringtones, podcast snippets or voice notes. Compress oversized audio files so they fit email and upload limits while keeping them clear. Every conversion and edit happens locally in your browser using WebAssembly, which means your audio never leaves your device and the tools work quickly even on large files.
