Does this Doc Converter work completely offline without internet?

Yes. Once the page is loaded, all processing runs locally on your device in WebAssembly and HTML5 Canvas. You can disconnect from the internet or use airplane mode and continue converting safely.

Are my files uploaded to a remote server or cloud?

No. 0mod operates on a zero-upload architecture. Your files never leave your local device, making it safe for confidential, legal, healthcare, or personal documents.

Is there any file limit, queue, or paid subscription?

No. Because conversion runs on your device hardware rather than metered cloud servers, there are no artificial file caps, queues, or subscriptions.

Document & Markdown Converter - Secure Offline PDF & HTML Tool

Convert documents between Markdown, PDF, HTML, and Rich Text formats securely inside your browser. 0mod provides a fast, private, and zero-upload document converter designed for developers, technical writers, and privacy-focused professionals.

Why Use 0mod Document Converter?

Converting Markdown notes to PDF or extracting raw text from PDF files often forces users to rely on cloud services that upload personal files to unknown remote servers.
