We built this project so anyone can convert files without paywalls, accounts, or hidden limits. Here is what that promise means in practice.
Every converter on ConvertX is free to use: no trials, no premium tiers, and no credit packs. We will never put core conversion features behind a subscription. Whether you convert one photo or a hundred files a week, the price stays zero.
Many image, audio, and video conversions run entirely in your browser. Your files never leave your device for those jobs. When server processing is required for documents or specialized formats, uploads are handled securely and removed automatically — typically within one hour.
Running servers and maintaining conversion engines costs money. Instead of charging users, we may show unobtrusive advertisements from partners such as Google AdSense. Ad revenue helps us cover hosting and development while keeping every tool free for everyone.
