Limitations

PDF compression works best on image-heavy documents and scanned pages. Files that are already optimized, mostly text, encrypted, or digitally signed may shrink only slightly, and repeated compression can soften embedded images.

Privacy note

PDF compression uses secure cloud processing so large documents can be optimized reliably. Files are used only to complete the conversion, and you should avoid uploading documents that require a regulated storage agreement or contain secrets you cannot share with a processor.
