How to Use Compress PDF

Master PDF Compressor in Minutes

PDF files often become too large when they include images, scanned pages, or graphics. Large PDFs can be difficult to upload, share, or email. Our PDF Compressor tool provides a quick, reliable, and secure way to reduce PDF file size without compromising quality—no software installation or account required.

Complete Step-by-Step Guide

Step 1: Upload Your PDF Files

Getting started is easy. Choose any of the upload methods below:

• Click to Browse: Select the "Choose PDF" or "Select Files" button and pick your PDF from your device.
• Drag and Drop: Drag your PDF from your folder and drop it into the upload box.
• Multiple File Upload: Some versions allow uploading several PDFs together. Hold Ctrl (Windows) or Cmd (Mac) while selecting files.

Supported File Types:

• PDF (.pdf)
• File size: Up to 50MB per PDF
• Multiple file support varies by tool

Pro Tip: For best results, upload the original high-quality PDF before it has been compressed elsewhere.

Step 2: Configure Your Settings (If Applicable)

Depending on the tool version, you may be able to customize output settings:

• Compression Level: Choose between high, medium, or low compression. High compression gives a smaller file, while medium preserves more clarity.
• Page Selection: Compress the whole file or only selected pages.
• Output Format: Some tools offer alternative formats if needed.
• Quality Options: Adjust resolution for images inside the PDF.

Step 3: Process Your Files

Click the "Compress," "Process," or "Reduce Size" button to begin. The tool will:

• Upload your file securely using encrypted HTTPS
• Optimize images, remove unnecessary data, and reduce file size
• Generate a smaller, high-quality PDF
• Prepare the compressed file for download

Processing Time: Most files compress within seconds. Larger PDFs may take up to a minute.

What Happens During Compression:

• Your file is stored temporarily in a secure environment
• Unnecessary metadata and hidden layers are removed
• Images are optimized for clarity and reduced size
• All files are deleted automatically within 1 hour

Step 4: Download Your Compressed PDF

After processing, download your smaller PDF with one click:
