Compress PDF: common questions
How does Compress PDF handle my input?
Processing happens on your device. OmniKit does not upload or save your tool input or results.
Do I need an account for Compress PDF?
No account is required for the main tool. Optional favorites and account features are separate from processing your input.
Will PDF compression always make a file smaller?
No. A PDF that is already optimized may not shrink. Compression results depend on the source document; verify the output rather than relying on a promised percentage reduction.
