About PDF Compressor
This tool reduces PDF file size by re-rendering each page as a compressed JPEG image and rebuilding the document. Everything runs in your browser using pdf.js and pdf-lib — your files are never uploaded anywhere.
How it works

- Upload or drop a PDF file.
- The tool renders each page and rebuilds the PDF with compressed images.
- Compare the before/after sizes and download the result.
