Frequently asked questions

Everything you need to know about converting video online.

All questions
Yes, completely. There are no hidden fees, watermarks or daily limits. You don't even need to create an account — just open the page and convert.
No. The entire conversion happens locally in your browser using modern web technologies. Your files never leave your device, which makes the tool safe even for private or confidential footage.
You can convert to MP4, WebM, MOV, MKV, AVI, FLV, 3GP, M4V, MPEG, TS and WMV. As input, the converter also accepts additional formats such as MTS, M2TS and OGV.
Files up to 4 GB are supported when converting to MP4, MOV, WebM or MKV. For other output formats the limit is 300 MB.
The converter uses quality-focused encoding settings, so any quality change is minimal and usually unnoticeable. Keep in mind that converting between lossy formats always re-encodes the video, so we recommend starting from the highest-quality source you have.
MP4, MOV, WebM and MKV use a hardware-accelerated fast path, so they convert very quickly. Legacy formats like AVI, FLV or WMV are processed by a full software encoder in your browser, which takes a bit longer — the result is worth the wait.
No. Everything runs in your browser — Chrome, Firefox, Safari or Edge on any desktop or laptop. There's nothing to download or install.
