Browser-based file converters allow users to transform images, documents, and multimedia formats directly within their web browser. They are used by digital workers, developers, and privacy-conscious professionals seeking quick conversions without installing desktop software. Unlike traditional cloud converters that upload files to remote servers, these tools process data locally on the client side to protect sensitive information and eliminate upload wait times.
