Frequently Asked Questions

What is AVI?

AVI (Audio Video Interleave) is a multimedia container format developed by Microsoft. It stores both video and audio data and is commonly used for downloaded videos and older camera recordings.

Is there a file size limit for AVI conversion?

No server-side limit since nothing is uploaded. The practical limit is your device RAM. Most modern computers handle AVI files up to several gigabytes.
