Recordings, meetings, voice memos — sound is often more private than text. We build privacy protection into the product architecture.
WUJIEE Audio Tools takes privacy seriously at the architecture level: privacy-sensitive steps are processed on-device, and your data is destroyed when you close the page. We never store, share or analyze your audio content.
Eight basic tools with no sign-in: format conversion, trimming, merging, volume, speed, fades, online recording and audio info; five advanced tools — speech to text, subtitles, denoising, vocal separation and text to speech — are free after sign-in.
Convert formats, cut clips on the waveform and join recordings into one — the everyday basics, no sign-in needed.
Boost quiet recordings, speed up lectures and podcasts, add fades for smooth starts and endings — all the finishing touches.
Record straight in the browser and export MP3/WAV, or check sample rate, bitrate and channels before transcoding or publishing.
