Compress PDF

Reduce PDF file size by re-encoding pages as optimized JPEG images.

Drastically reduce your PDF file size by re-encoding pages as optimized JPEG images. Unlike basic optimization which only removes redundant data, our compress tool rasterizes each page into a high-quality JPEG image then rebuilds the PDF — achieving dramatically smaller file sizes ideal for email attachments, website uploads, and mobile viewing.

About This Tool

Drastically reduce your PDF file size by re-encoding pages as optimized JPEG images. Unlike basic optimization which only removes redundant data, our compress tool rasterizes each page into a high-quality JPEG image then rebuilds the PDF — achieving dramatically smaller file sizes ideal for email attachments, website uploads, and mobile viewing.

How to Use

  1. 1Upload your PDF file by clicking the upload area or dragging and dropping it.
  2. 2Adjust the Image Quality slider — higher values preserve more detail but produce larger files.
  3. 3Set the Output DPI — lower values (72-150) for web use, higher (200-300) for print quality.
  4. 4Click "Compress PDF" to rasterize and rebuild the document.
  5. 5Wait for processing. Each page is rendered as a JPEG and assembled into a new PDF.
  6. 6Click "Download Result" and compare the output file size with the original.

Pro Tips

  • Tip 1A quality setting of 60-70% provides a good balance of size reduction and visual quality.
  • Tip 2Text-heavy documents compress exceptionally well since pages become JPEG images of text.
  • Tip 3Start with a quality of 80% and decrease if you need smaller file sizes.
  • Tip 4This tool rasterizes all content — text becomes part of the image and is no longer searchable.
