WAV and MP3 conversion happens right here in your browser tab. Nothing is uploaded to a server — open your network tab if you don't believe it.
WAV files are processed almost instantly. MP3 files require browser-based conversion, so larger files may take a few seconds to complete — every file is converted at the best possible quality automatically. Supports WAV → MP3 and MP3 → WAV, in either direction.
Every tool on Quikbench follows the same rule: your files are read, converted, and turned into a download entirely inside this browser tab — nothing is ever uploaded to a server.
Converts between WAV and MP3 using the Web Audio API to decode audio and lamejs to encode MP3 — both running locally in your browser. As with the other tools, audio files are never sent to a server.
Convert one audio file at a time with its own format dropdown, or queue multiple files and send them all to the same target format in a single batch — exactly like the image converter.
MP3 encoding uses lamejs, a JavaScript MP3 encoder that runs entirely client-side, so you get a genuine, playable MP3 or WAV file without a round trip to any server.
