Frequently Asked Questions
Which format should I use for sharing?
MP4 (H.264) is the safest choice. It plays on every device, browser, and social media platform. WebM is a good alternative for web-only use. GIF is best for short animated clips.
How do I convert a MOV file from my iPhone?
Drop the .mov file into the converter and select MP4 as the output format. The video will be re-encoded to H.264 + AAC, which plays on all devices and platforms.
Why are GIF files so large?
GIF is an old format that doesn't compress efficiently. A 10-second video clip can produce a 20+ MB GIF. Keep GIFs short (under 10 seconds) and at lower resolution for reasonable sizes. For longer animations, consider WebM or MP4 instead.
