Compress PDF

What Does This Tool Do? Reduce PDF file size for easier sharing.

Compress PDF User Guide

Reduce PDF file size to meet upload limits. If the original PDF is already optimized, its size may not decrease.

Easy Step-by-Step Instructions

Select a PDF to compress.

Select a quality level, run the process, and compare the original and output file sizes.

Enlarge small text, scanned images, and stamped areas to check whether they are readable.

Sample Input and Results

For PDFs containing many photos or scans, compare results at lower quality settings. Compression may have little effect on text-heavy PDFs.

How Calculations & Processing Work

Depending on the available PDF processing method, the tool adjusts image resolution or compresses document streams. The quality value does not represent the compression ratio.

When Using the Results

A specific compression ratio or acceptance by the receiving institution is not guaranteed. Keep separate copies of important original documents and verify the validity of electronic signatures.
