## What does this tool do?

PDF Compressor reduces the file size of any PDF document by re-encoding its pages as optimized JPEG images. The compression runs entirely in your browser using pdf.js to render pages and pdf-lib to reassemble the result. No upload, no server processing, no waiting in queue.
