Tips: Many online video mergers can also help to merge AVI files. Yet, I don’t suggest online video merging, for there is usually a size limit and it needs additional time to upload and download as well. Considering that, it’s more efficient to merge videos on PC. However, if you only have a few small AVI videos, the online video joiner is also a nice option.
