Frequently asked questions

Are these MP4 converters free?

Yes — every MP4 tool on Toolspace is 100% free with no signup, watermarks, or file-count limits.

Do my MP4 files upload to a server?

No. All MP4 conversions run entirely inside your browser using WebAssembly and Canvas APIs, so your files never leave your device.

What is the largest MP4 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 MP4 files up to several GB without issue.

Which browsers work with Toolspace MP4 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.
