Frequently Asked Questions
Are my videos uploaded to a server?
No. All video processing happens entirely in your browser using WebAssembly technology (FFmpeg.wasm). Your videos never leave your device.
Is there a file size limit?
The limit depends on your device's available memory. Generally, files up to 2GB work well on most modern devices. Larger files may take longer to process or may not work on devices with limited RAM.
Why is processing slow?
Processing happens in your browser, so speed depends on your device's CPU. Large files or complex operations take longer. First-time use may be slower as the processing engine loads.
Which browsers are supported?
Modern versions of Chrome, Edge, Firefox, and Safari on desktop. Mobile browsers are supported but may have limitations with large files due to memory constraints.
Is this tool free?
Yes! VideoTools is completely free to use with no limits, no accounts required, and no hidden costs.
