Frequently asked questions

Are these CSV converters free?

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

Do my CSV files upload to a server?

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

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

Which browsers work with Toolspace CSV 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.
