How to Reduce PDF File Size

This tool helps you shrink the file size of your PDF documents, making them easier to email, share, or store. The primary way it achieves this is by optimizing and re-compressing the images within the PDF, which are often the largest contributors to file size.

How It Works: A Step-by-Step Guide

  1. Upload Your PDF: Click the upload box to select a PDF file from your computer. The file is not sent to a server; it stays in your browser.
  2. Adjust Image Quality: Use the quality slider to find the perfect balance. A lower quality will create a much smaller file, which is great for emails. A higher quality preserves more detail for professional documents.
  3. Compress the File: Click the "Compress PDF" button. Our tool processes each page, re-compressing the images to your specified quality level.
  4. Download the Result: A summary will show you the original size, the new size, and how much space you saved. Click "Download" to save your optimized PDF.
