MP4 to AVI Converter
Convert your MP4 videos to AVI format with this high-quality MP4 to AVI converter. Fast, secure, and easy to use.
💡 How to Use This Tool
Converting your MP4 file to an AVI takes just a few clicks. Follow these simple steps:
Upload Your MP4
Click the upload area or drag and drop an MP4 file (up to 1 GB).
Conversion Starts Automatically
Your file is uploaded and a task is queued on my server instantly — no button to press.
Monitor Progress
The Recent Tasks list below the upload area tracks your conversion in real time (queued → processing → completed). You can also navigate away — a floating Tasks button in the bottom-right corner of every page lets you check status and download your file from anywhere on the site.
Download Your AVI
Once complete, a green Download button appears on the task row. Click it to save the AVI to your device. A live countdown shows how long the link remains valid — download links expire after 90 minutes.
Refresh an Expired Link
If 90 minutes have passed, the Download button is replaced by an amber Refresh Link button. Click it to generate a fresh 90-minute link on demand — no need to re-upload or re-convert.
Delete When Done
Each task has a trash icon. Clicking it immediately removes the task and permanently deletes the output file from my servers — giving you full control over your data at any time.
