常见问题
Are my documents uploaded to this website?
No. The document tools run in your browser. Your file is not sent to this server.
Can every document reach the exact KB limit?
No. The tool safely optimizes document structure and metadata where possible. Some files need a higher limit because their images or pages are already compressed.
