AVI is a multimedia container format that can store both audio and video data. It uses less compression and takes up more space than many other formats.
Clideo's AVI Joiner lets you convert your video to any desired format besides merging. It's online, so you don't need to download and install anything to your device.
The tool allows uploading files up to 500 MB each free of charge. It's usually more than enough, but if you have bigger files, you can subscribe to Clideo Pro and edit your files without limits.
How to combine multiple AVI files into one
Upload AVI videos
Click on the blue button "Choose files" above to add AVI and other files to the tool.
If your videos are stored online, call a dropdown menu by clicking on the small arrow on the right of the button. There you'll find options to upload from Google Drive, Dropbox, or from anywhere via a link.
Combine two or more AVI files
Now upload more files if you like. A little reminder: you can merge not only AVI but also any other formats of video and images together.
You can reorder the added files by dragging and dropping them on the timeline. Choose aspect ratio and crop the frame if needed. If there are pictures, set their duration.
The tool allows adding music. You can upload it from a device or online source. Then cut it and adjust the volume.
Select an output format if needed and click "Merge".
Save the merged AVI
Download the result to your device or upload to Google Drive or Dropbox. If you want to change something, just click "Back to edit", so that you don't need to start over.
