Frequently asked questions
Are my files uploaded to a server?
No. Everything runs inside your browser, so your files never leave your device. Nobody — including us — can see them.
Is it really free?
Yes. There is no sign-up, no watermark and no daily limit. The site is supported by ads.
Why does the first conversion take longer?
The video engine (about 30 MB) downloads once, then your browser caches it.
Is there a file size limit?
Files up to about 1.5 GB work on most computers. Phones handle smaller files best.
