Frequently asked questions
General
Is Video Converter Online really free?
Yes. Converting and editing videos is free with no watermark and no account. We offer an optional Pro plan ($6.99/month or $49/year) for power features like 4K export, AI subtitles and unlimited batch.
Are my videos uploaded to your servers?
No, never. Your files are processed entirely on your own device in the browser, using FFmpeg compiled to WebAssembly. We never receive, see or store your videos, not even temporarily. That is also why there is no upload wait.
Which formats are supported?
Input: practically any video, audio or image format (MP4, MOV, MKV, AVI, WebM, WMV, FLV, MPEG, TS, 3GP, GIF, MP3, WAV, M4A, FLAC, OGG, OPUS and more). Output: MP4, WebM, MOV, MKV, AVI, M4V, WMV, FLV, MPEG, TS, 3GP, OGV, GIF, animated WebP, APNG, MP3, WAV, M4A, AAC, OGG, OPUS, FLAC, AIFF, WMA, AC3, JPG and PNG.
Is there a file size limit?
There is no upload limit because nothing is uploaded. The practical limit is your device’s memory: files up to about 2 GB work well on most computers. Phones handle smaller files.
Does it work on iPhone, Android and Mac?
Yes. It works in any modern browser: Chrome, Safari, Edge and Firefox on Windows, macOS, Linux, ChromeOS, iOS and Android. Native mobile apps are coming soon.
Why is conversion sometimes slower than desktop software?
Browser processing uses your device’s CPU via WebAssembly, which is a little slower than native apps. Choosing H.264 MP4 and the “Very fast” encoding speed gives the quickest results. Simple container changes (e.g. MKV → MP4) are instant.
Do you add a watermark?
Never. Not on the free plan, and not on Pro.
How do I cancel Pro?
Anytime from your Account page (Manage billing). You keep Pro until the end of the period you paid for.
