Why is it free?
I believe simple tools should be simple to use: no accounts, no paywalls, no "upgrade to Pro" after your third file. Because everything runs in your browser, there are no servers processing your files and almost nothing to pay for. If Multi Converter saves you time, a small donation helps keep it online and growing.
☕ Buy me a coffee on Ko-fiFrequently asked questions
Is Multi Converter really free?
Yes, completely. There are no subscriptions, no premium plans, no watermarks and no limits. The project is supported only by voluntary donations on Ko-fi.
Do I need to create an account?
No. Just open a tool, drop your files and download the result.
Are my files uploaded to a server?
No. Every conversion runs inside your browser, on your own device. Your files are never sent anywhere, which makes it private and safe for personal documents.
Is there a file size limit?
There is no artificial limit. Very large videos depend on how much memory your device has.
Does it work on my phone?
Yes. It works in any modern browser on Android, iPhone, Windows, Mac and Linux.
