About AnyConverter

AnyConverter is an independently built site that converts images, documents, spreadsheets, and data files entirely inside your browser. There is no backend server that receives your files — conversion runs on your own device using JavaScript and WebAssembly libraries (pdf.js, pdf-lib, mammoth, xlsx, and others), and the result is downloaded straight from the page.

The project started from a simple frustration: most free online converters require uploading a file to a stranger's server, which is slow, and a bad idea for anything even mildly sensitive (a payslip, a signed contract, a personal photo). Running the conversion client-side removes that trade-off entirely — you can even disconnect from the internet after the page loads and conversions keep working.

The site is built with Next.js and hosted on Vercel, and is supported by advertising rather than subscriptions or accounts — see the Privacy Policy for details on ads and analytics. It's maintained by a solo developer; if you run into a bug or want a format added, the Contact page has the fastest way to reach me.
