Frequently Asked Questions

Why convert AVI to MP4?
AVI is an older format that produces large files and has limited support on modern devices and browsers. MP4 offers better compression, smaller file sizes, and universal playback compatibility—essential for sharing videos from your Sydney holiday.
Will the converted MP4 be smaller than the original AVI?
Yes, typically MP4 files are 50-70% smaller than AVI files at equivalent quality. AVI uses older, less efficient codecs while MP4 uses modern H.264 compression that delivers excellent quality at much smaller file sizes.
Does converting AVI to MP4 lose quality?
Our converter uses high-quality H.264 encoding settings. While AVI and MP4 use different codecs, the quality difference is typically minimal. The significant reduction in file size makes the conversion worthwhile.
What is the maximum file size?
You can convert AVI videos up to 50MB in size. Since AVI files tend to be large, you may need to convert shorter clips or lower resolution videos.
Are my videos safe and private?
Absolutely! All AVI to MP4 conversion happens locally in your web browser. Your videos never upload to any server. Once you close the page, all data is permanently deleted.
