Frequently Asked Questions
Is MP4 smaller than AVI?
Usually yes. AVI files often use older compression (like DivX/XviD) or no compression. MP4 uses H.264 which is much more efficient, saving 30-50% space.
How to play AVI on iPhone?
You cannot play AVI natively on iPhone. Use this converter to change it to MP4, then you can save it to your Photos or share it.
Does it support large files?
Yes, we handle large AVI movies. Just upload, and the conversion happens in the cloud.
Is quality lost?
MP4 is highly efficient. While some re-compression occurs, the visual difference is usually negligible for standard viewings.
