Turn your AVI videos into WebM, right in your browser — no upload, no signup.
AVI to WebM Converter turns an old .avi file into WebM, the format built for the modern web — it plays natively in every major browser without a plugin and usually lands at a smaller file size for the same look. It's a great way to bring an old recording or archived clip onto a modern website or web app, where every extra megabyte slows the page down. Add your AVI files, click convert, and download a .webm ready to embed — everything happens right here in your browser, so your footage is never sent to a server.
Drag and drop your .avi files, or click to browse. You can add several at once.
Click Convert and a progress bar shows you how it's going. This one always needs a full re-encode, so it can take a few minutes for a longer clip.
Save each .webm file individually, or download every converted file at once as a .zip.
Your videos are processed locally and never leave your device.
Works straight in your browser — no software, no account, no email.
WebM is the format modern browsers were made for — no plugins, no compatibility guessing.
