Frequently Asked Questions

Everything You Need to Know

How does ClipShrink extract audio in under 1 second?
Unlike cloud converters that make you upload a 200MB video over slow Wi-Fi to a remote server, ClipShrink compiles FFmpeg into WebAssembly. It runs locally on your computer CPU and discards the video stream (-vn) in browser RAM without upload wait times.
How is ClipShrink better than 123apps (audio-extractor.net)?
123apps forces you to upload your personal video to their remote servers and covers the screen with 4–6 banner ads. ClipShrink is 100% ad-free, processes your files locally in RAM with complete privacy, and includes a live inline player to verify audio before downloading.
Do my video or audio files ever touch an external server?
Never. Video files are loaded into your browser's private memory and processed locally. Zero data is transmitted, stored, or inspected by third parties.
