Smart PDF Optimization

Heavy PDF files are difficult to email, upload, or print. Our compression engine intelligently reduces the file size of your PDF documents by downsampling high-resolution images, compressing fonts, and removing metadata.

  • Multiple Levels: Choose from Normal, High, Extreme, or Insane depending on your needs.
  • Batch Mode: Upload multiple PDFs at once. The engine will compress them all and package them in a ZIP archive.
  • Free of Charge: No premium accounts or payments needed. Completely free.

Secure Processing

We process your files securely on our servers using optimized tools like Ghostscript.

Files are written to encrypted temporary directories, compressed, and immediately deleted after your download starts. We guarantee that your private documents remain secure.
