What Is a Compress PDF Tool?
A Compress PDF tool is an online utility that reduces the size of PDF documents by optimising images, fonts, metadata, and internal file structure. The goal is to make PDFs easier to store, upload, share, and publish—without affecting readability or usability.
PDF compression is essential for modern digital workflows where speed, compatibility, and storage efficiency matter.
Why PDF Compression Matters in 2025
1. Digital File Size Restrictions
Government portals, job applications, LMS platforms, and email services enforce strict file size limits.
2. Faster Workflows
Smaller PDFs upload and download faster, saving time for teams and individuals.
3. Cloud Storage Optimization
Compressed files reduce cloud storage costs and sync faster across devices.
4. Mobile Accessibility
Optimized PDFs open quickly on smartphones and tablets, even on slow networks.

| High-resolution images | Massive file size increase |
| Scanned documents | Image-only PDFs with no text optimization |
