When to compress a PDF
Large PDFs can be difficult to email or upload to forms, job sites, or cloud storage. Compressing reduces file size by optimizing images and streamlining the document structure while keeping text and graphics readable. Typical uses include meeting email attachment limits, speeding up web uploads, and saving storage space. Our compressor runs in your browser so your files never leave your device.
How PDF compression works
After you upload your PDF above, the tool analyzes the file and applies compression. You can often achieve a 30–50% size reduction with minimal visible loss in quality for text-heavy documents. When the process finishes, download the compressed PDF. For a detailed walkthrough, read our guide to compressing PDFs.
