What Is PDF Compression?
PDF compression is the process of reducing the file size of a PDF document without significantly affecting its quality. Large PDF files often contain high-resolution images, embedded fonts, and uncompressed data streams that take up excessive storage space. By applying intelligent compression algorithms, these files can be reduced by 30–90%, making them easier to share via email, upload to websites, and store on your device.
What Is Compress PDF Used For?
- Email attachments — Most email providers limit attachments to 20–25 MB. Compressing your PDF ensures it fits within these limits.
- Web uploads — Government portals, job application systems, and university submission platforms often enforce strict file size limits of 1–10 MB.
- Storage optimization — Reduce disk space usage when archiving large volumes of documents.
- Faster sharing — Smaller files upload and download faster, improving productivity when collaborating with colleagues.
