Frequently asked questions

Are these AVI converters free?

Yes — every AVI tool on Toolspace is 100% free with no signup, watermarks, or file-count limits.

Do my AVI files upload to a server?

No. All AVI conversions run entirely inside your browser using WebAssembly and Canvas APIs, so your files never leave your device.

What is the largest AVI file I can convert?

There's no hard limit — since the work happens in your browser, the practical ceiling is your device's available RAM. Most modern devices handle AVI files up to several GB without issue.

Which browsers work with Toolspace AVI tools?

Chrome, Edge, Firefox, and Safari on both desktop and mobile. For the best speed with video/audio conversion, use a Chromium-based browser (Chrome/Edge) on desktop.
