Frequently Asked Questions
How much will my video be compressed?
Results depend on the original video's bitrate and content. High-bitrate videos (4K, 1080p 60fps) typically see 40–70% size reduction at High Quality settings. The Max Compression preset can reduce files by up to 80% with some quality trade-off.
Is my video uploaded to a server?
Never. All compression happens entirely in your browser using FFmpeg compiled to WebAssembly (WASM). Your video file never leaves your device, so your privacy is fully protected.
What format is the output video?
The compressed video is always saved as MP4 (H.264 video + AAC audio), which is the most widely supported format for web, mobile, and desktop playback.
Why does compression take a while?
Video compression (H.264 encoding) is computationally intensive. It runs fully in your browser using FFmpeg WASM, which is slower than native encoding. Larger or longer videos take more time. This is normal — your video is never sent to a server.
