About Fast File Conversion

Fast File Conversion is a small set of file conversion tools that run entirely inside your browser. There's no server processing your files, no account to create, and no watermark added to your results.

Every converter uses JavaScript built into your browser — the Canvas API for images, and lightweight parsers for data formats like CSV, JSON, XML, and YAML. Your file is read into memory locally, converted locally, and offered back to you as a download. It's never transmitted anywhere.

The site is intentionally simple: focused, single-purpose tools rather than one crowded do-everything page. New converters are added over time — if there's a format pair you'd like to see, feel free to get in touch.
