Why convert AVI to WEBM?
AVI is a legacy Microsoft container from the 90s that creates massive files and fails to play on mobile devices. WEBM is the open HTML5 standard designed for the web. Converting ensures your video plays natively on every browser without plugins.
How fast is the transcoding?
It is nearly instant. We utilize a distributed cloud transcoding cluster to process your video off-device. This allows us to re-encode heavy uncompressed AVI files into lightweight WEBMs in mere seconds.
Is Converter App free to use?
Yes. This tool is 100% free. We believe valid file tools should be open access: there are no hidden fees, no watermarks added to your output, and absolutely no account registration or email sign-up required.
Will the audio remain synced?
Absolutely. AVI files are notorious for audio desynchronization during conversion due to variable bitrates. Our engine uses advanced timeline mapping to ensure your audio track stays perfectly locked to the video frames throughout the process.
What is the difference between AVI and WEBM?
Think of AVI as a heavy storage box—it preserves raw data but is difficult to share. WEBM is a modern streaming format. It uses advanced VP8/VP9 compression to deliver high visual fidelity at a fraction of the file size, making it the superior choice for the web.
Is my video data safe?
We prioritize your privacy. All transfers are secured via 256-bit SSL encryption. Furthermore, we operate on a strict volatile-memory basis: your input AVI and output WEBM are automatically and permanently wiped from our servers within 2 hours.
