Frequently asked questions
The honest answers to the things people usually wonder about a free online converter.
Is convert-buddy really free?
100% free. No premium tier, no daily quota, no credit card asked, no “upgrade for unlimited”. There is no catch. ❤️
Do my files stay on my device?
Yes. Every conversion runs inside your browser, locally — no file ever leaves your device. Once the page is loaded, you can even disconnect from the internet and the converter keeps working.
Is there a file size or file count limit?
No. The only constraint is the memory your browser has access to. On a modern desktop, multi-gigabyte files work fine. There is no daily cap and no limit on how many files you convert.
Do I need to create an account?
No signup, no email asked, no password to remember. Open the page and use it.
Are there ads or trackers?
No analytics cookies, no third-party scripts, no ads, no fingerprinting. The page does exactly what it says it does — and nothing else.
Why is this free? Where is the catch?
Because the work runs on your device, we have no server cost to recover. There is no incentive to monetize you. convert-buddy is built and run as a public utility — there is no catch, no upsell, no “premium when you grow”.
Which devices and browsers are supported?
Any modern browser: Chrome, Firefox, Edge, Safari, Brave. On Windows, macOS, Linux, iOS and Android. No installation, no extension required.
