Frequently Asked Questions about Compress PDF
Will compression blur my text?
No. Vector text remains mathematically defined; only unoptimized object trees and raster data are streamlined.

No. BizAiPro processes your documents 100% locally in your web browser using client-side WebAssembly and modern JavaScript. Your files never leave your computer.
