Why Compress PDF Files?

Large PDF files can be a hassle to share via email, upload to websites, or store on your device. Compressing your PDFs reduces their file size significantly, making them easier to handle. Whether you're applying for a job, submitting government forms, or sending a portfolio, a smaller PDF ensures faster uploads and downloads.

How Does PDF Compression Work?

Our PDF compressor works by optimizing the internal structure of the file and reducing the size of images and fonts embedded within it. We offer three compression levels:

  • Low Compression: Best for high-quality printing. Retains mostly original quality.
  • Medium Compression: The balanced choice. Good quality and good file size reduction. Ideal for documents.
  • High Compression: Maximum size reduction. Images may lose some quality, but the file becomes very small. Perfect for web sharing.

How to Compress PDF on Mac (Free Preview Method)

Mac users can compress PDFs natively without any extra software:

  1. Open your PDF with Preview.
  2. Go to File > Export...
  3. Click the Quartz Filter dropdown menu.
  4. Select Reduce File Size.
  5. Save the new file.

Warning: The default 'Reduce File Size' filter in Mac is aggressive and can make images blurry. Our tool gives you more control with Low, Medium, and High compression options.

Reduce PDF Size Without Losing Quality

One of the biggest concerns with compression is quality loss. Our smart compression algorithms are designed to maintain the highest possible quality while reducing file size. Text remains sharp and readable, while images are optimized efficiently. You can choose the compression level that best suits your needs.

Compress PDF for Email

Most email providers (like Gmail, Outlook, Yahoo) limit attachment sizes to 20MB or 25MB. If your PDF exceeds this, you can't send it. Our Compress PDF tool can easily shrink your document to well under this limit, ensuring your important emails are delivered without issues.

Optimize PDF for Web Uploads

Government portals, job application sites, and university admissions often have strict file size limits (e.g., 'Upload PDF under 2MB'). Use our tool to quickly reduce your file size to meet these requirements without struggling with complex software.

Compress PDF Securely Online

Your privacy is paramount. When you upload a file to our PDF compressor, it is processed securely using SSL encryption. We do not view, share, or store your documents. All files are automatically deleted from our servers shortly after processing, ensuring complete data protection.

How to Compress PDF on Mac & Windows (Native Methods)

If you don't want to use an online tool, here are native ways to compress PDFs:

On Mac (Preview App):

  1. Open your PDF with Preview.
  2. Go to File > Export.
  3. In the 'Quartz Filter' dropdown, select Reduce File Size.
  4. Save the file. Note: This often reduces quality drastically with no control.

On Windows (Print to PDF):

  1. Open your PDF in a browser (Edge/Chrome).
  2. Press Ctrl+P (Print).
  3. Select Microsoft Print to PDF as the printer.
  4. This re-saves the file, sometimes reducing size, but results vary.

Why Use Our Tool Instead?

Our tool gives you control over the compression level (Low, Medium, High), ensuring you don't end up with a blurry, unreadable document like the Mac Preview method often produces.
