What is a File Converter? Complete Guide
A file converter is a free online tool that transforms files from one format to another, enabling compatibility across different applications and platforms. Our 2026 file converter goes beyond basic tools with image conversion supporting PNG, JPG, and WebP formats with quality preservation, document conversion for TXT and JSON files, client-side processing ensuring complete privacy, instant conversion with immediate results, no file size limitations, and free unlimited use. File conversion is essential for web designers optimizing images for faster loading, developers working with different data formats, professionals sharing documents in compatible formats, and anyone needing to transform files for specific software or platforms. Unlike online converters that upload your files to remote servers, our converter processes everything locally in your browser using advanced Canvas API and JavaScript libraries, ensuring your sensitive documents, personal photos, confidential data, and proprietary information remain completely private and secure on your device.
