Why use DocFlexi for this requirement?
Unlike upload-based converters, DocFlexi uses browser APIs to process the file on your device. That makes it useful for identity photos, signatures, immigration documents, and marketplace assets that should not be sent to a third party. The generated download is created only after you choose to export it.
