About PDF Compressor
This PDF Compressor page is organised around the task described in the tool interface. Compress PDF files directly in your browser. The result changes when the source data or selected options change, so it is easy to run a second comparison.
A practical way to use it is to prepare a working copy for sharing, filing or review without changing the original document. Start with a representative input, inspect the first result, then adjust one setting at a time if you need a different outcome.
Processing stays in the browser where the individual feature supports it. Live public checks use a protected, rate-limited site endpoint; avoid unnecessary sensitive data.
