Frequently asked questions
Is the video uploaded to a server?
No. Processing happens in your browser, with FFmpeg running on your device. The file never leaves your computer or phone.
Why does it take a while?
The first time, the browser downloads the video processor (about 30 MB), which is then cached. Long videos take longer because everything runs on your device; on a computer it is much faster than on a phone.
Is it really free?
Yes, 100% free. No sign-up, no subscription and no usage limits. All Tools123 tools are free and run right in your browser.
