Any file up to 500 MB. Drop several files and they come back as one ZIP. Many image, audio and video conversions run in your browser; anything else is uploaded and removed within the hour.
Convert your Rich Text Format (RTF) documents into web-ready HTML files instantly. This tool is ideal for web developers and content creators who need to migrate structured text to a browser-compatible format.
RTF is a proprietary document format designed for cross-platform text exchange, while HTML is the standard markup language used for rendering content on the web. During the conversion process, our tool maps RTF styling elements, such as font formatting and paragraph alignment, into equivalent HTML tags and CSS properties. This ensures that the logical structure of your document is preserved while adapting the raw text for web environments.
The conversion from RTF to HTML is performed without any loss of data, ensuring that your text content and formatting remain intact. You will find that the output HTML file size remains nearly identical to the original RTF document.
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.
