What is the PDF Compressor?

The PDF Compressor reduces your PDF file sizes using three quality presets: Low Compression (best quality, minimal reduction), Medium (balanced), and High Compression (smallest file, lower quality). Upload multiple PDFs for batch compression. See before/after size comparison for each file. Download individually or as a ZIP. All compression runs in your browser.
