Frequently asked questions regarding Compress PDF
How does client-side PDF compression work?
Our engine optimizes PDF internal structures, strips redundant metadata, flattens redundant font streams, and compresses image objects to significantly lower the file weight.

No! All text vectors, fonts, and hyperlinks remain sharp and fully readable.
Are my confidential documents uploaded anywhere?
Never. Compression is executed 100% inside your local browser memory using modern WebAssembly and Canvas APIs.
