Complete 100% client-side execution ensures your documents remain strictly confidential on your own machine.

Why Choose Our 100% Private Tool?

Your files never leave your computer.

Most free online PDF tools require uploading confidential files to remote internet servers. This exposes sensitive corporate contracts, personal records, or legal documents to server logging and security risks.

Our converter operates with a 100% client-side architecture. Powered by WebAssembly and local JavaScript renderers, all file conversions happen inside your device's browser memory—guaranteeing total GDPR and HIPAA compliance.

Frequently Asked Questions (FAQ)

Is it safe to process my confidential documents here?

Yes, 100%. This tool operates with a client-side JavaScript architecture. When you select or drop a file, processing happens entirely inside your local browser memory. Your files are never uploaded, transferred, or stored on any external web server.

What file formats are supported? Can I mix them?

The tool supports Microsoft Word files (.docx), plain text (.txt), web pages (.html), and common images (.jpg, .png, .webp, .gif).

Note: Standard .pdf files should be loaded into the Compress PDF tab for optimization.

Can I convert password-protected documents?

No. Because the engine runs locally inside a secure browser sandbox, it cannot decrypt password-protected or encrypted files. Please unlock your file before converting.

Is there a file size limit?

There are no artificial file size caps because files are not uploaded over the internet. Processing speed depends on your device's local memory (RAM) and processor capacity.
