Questions
Frequently asked questions
Is AVI to MP4 conversion free?
Yes. It is free, needs no account and has no watermark.
Does converting AVI to MP4 lose quality?
MP4 is a lossy format, so a very small amount of detail is traded for a smaller file. Higher quality settings keep the result very close to the original.
Are my files uploaded to a server?
No. The work happens inside your browser on your own device. Your files are never sent to us or to anyone else, and they are gone when you close the page.
