What Is a PDF Compressor?

A PDF Compressor is a tool that reduces the file size of PDF documents by optimizing
images, fonts, and internal structure. This makes files easier to share, upload, and store
without changing the document’s content.

Why Compress PDF Files?

Large PDF files can be difficult to email, upload, or store. Compressing PDFs helps
improve performance and compatibility, especially when sharing documents online or
using mobile devices.

  • Send PDFs via email without size limits
  • Save cloud and local storage space
  • Upload documents faster
  • Improve accessibility on mobile devices

How PDF Compression Works

PDF compression works by reducing image resolution where possible, removing redundant
data, and optimizing internal file structures. The goal is to reduce file size while
keeping text readable and images clear.

Security and Privacy

Uploaded files are processed securely during compression. PDFs are not permanently
stored and are automatically removed after processing to protect user privacy.
