Frequently Asked Questions
Which video format should I choose?
MP4 (H.264) is the most widely compatible format and works on virtually all devices and platforms. WebM is ideal for web use with smaller file sizes. MOV is preferred for Apple devices.
Can I convert large video files?
Yes, but since conversion happens in your browser, performance depends on your device. Most devices handle files up to 500MB-1GB smoothly. For larger files, a desktop browser is recommended.
Does the conversion affect video quality?
You can choose the output quality during conversion. With high quality settings, the difference from the original is negligible. Lower quality settings produce smaller files.
