Open the working compress pdf tool
Compress a PDF without uploading it
Use browser-local compression when you want to compare file-size and quality changes without first uploading a document to a cloud converter.
What local processing means
The selected PDF is read by this browser and the output is built on your device. The application processing flow does not send the document bytes to PrivyPDF.
Understand the trade-offs
Structural mode is designed to preserve selectable text and interactive features. Raster modes can create smaller visual files but may remove text selection, annotations, links, bookmarks, and forms.
Privacy is not an absolute guarantee
Local processing reduces upload exposure but still depends on the security of your device, browser, extensions, and downloaded-file workflow.
