Common questions
Everything you need to know.
Absolutely! All processing happens locally in your browser using WebAssembly technology. Your videos never get uploaded to any server — they stay on your device the entire time. You can even disconnect from the internet after loading the page.
Browser-based video processing uses your device's RAM. Processing longer fragments may cause slowness or instability on lower-end devices. You can still process longer videos — just be aware it requires more memory.
We support MP4, MOV, and WEBM files with H.264 codec. iPhone videos (H.265/HEVC) are NOT supported — convert them to H.264 MP4 first using any online converter like CloudConvert.
About 20% of your selected fragment length on modern devices. A 5-minute fragment takes approximately 1 minute. Speed depends on your device CPU and how much silence is found.
