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 plain TXT files into structured HTML documents effortlessly. This tool is perfect for web developers and content creators who need to quickly transform raw text notes into web-ready markup.
TXT files represent pure, unformatted text containing only character data without any style definitions. In contrast, HTML is a markup language that adds structure, headings, and formatting tags to that same text. When converting TXT to HTML, our tool wraps your plain text content in essential HTML tags like <p>, <html>, and <body>, allowing your content to be rendered correctly in any web browser while maintaining the original text sequence.
Since both formats are text-based, the conversion process is lossless. All your original characters and data remain intact without any quality degradation.
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.
A quick guide to strengths and trade-offs of popular formats — so you pick the right one before converting.
