Why Compress PDF Under 100KB?

Many online forms, job applications, and email services have strict file size limits — often 100KB or less. Our intelligent compression reduces file size while preserving text clarity and image quality.

Pro Tips

  • Choose "Maximum Compression" for the smallest file size
  • Remove embedded fonts if the document is text-heavy
  • Convert color images to grayscale for even smaller sizes
  • Split large documents and compress each part separately
