Format and delivery
Convert between supported audio formats, reduce file size or choose a target bitrate when a player, platform or workflow expects a different codec, container or data rate.
Convert, trim, compress and fine-tune your audio in a simple studio with a live waveform preview.
MimiFile groups common audio conversion and editing tasks into one browser-based workspace. Use the format converter when you need a different file type, compression or bitrate controls when delivery size matters, trimming and fades for cleaner clips, LUFS normalization for more consistent perceived loudness, channel and sample-rate tools for technical compatibility, or tempo and gain controls for playback and production adjustments. Each route focuses on one distinct job so you can choose the operation that matches the problem instead of changing unrelated audio settings at the same time.
Convert between supported audio formats, reduce file size or choose a target bitrate when a player, platform or workflow expects a different codec, container or data rate.
Trim a time range, add a fade-in or fade-out, and raise or lower gain for straightforward edits that do not require a multitrack desktop project.
Use LUFS normalization when the goal is consistent perceived loudness. Use the volume tool for a deliberate dB gain change, or tempo when you need faster or slower playback while preserving pitch.
Switch between mono and stereo or resample to 44.1, 48 or 96 kHz when an audio, video, podcast or production workflow requires a particular channel layout or sampling rate.
Conversion changes the output format. Compression focuses on reducing the encoded file size or data rate. A conversion can also involve re-encoding, but the primary intent of the two tools is different.
Use volume adjustment when you want a specific gain change in decibels. Use loudness normalization when you want perceived loudness moved toward a selected LUFS target.
The tempo tool is designed to change playback speed while preserving pitch, which is different from a simple linked speed-and-pitch change.
44.1 kHz is common for music delivery, 48 kHz is common in video workflows, and 96 kHz is useful only when a production chain specifically needs the higher sampling rate.
