Your file never leaves your device

This tool runs entirely in your browser using pdf-lib. Nothing is uploaded. Safe for Aadhaar, PAN, bank statements, and confidential documents.

Are the sizes exact?

They are estimates based on average bytes per page. Actual output may be slightly over or under the target.

Are my files uploaded?

No. Processing runs entirely in your browser.
