What is the difference between Compress PDF and Compress PDF Lite?

Compress PDF is a server-side optimization tool that balances size and quality. Compress PDF Lite is a client-side PDF-to-Image compression tool, offering extreme size reduction while ensuring maximum privacy since files never leave your browser.

Will I still be able to copy the text after compression?

Yes. Unlike many other tools, Compress PDF Lite preserves a text layer above the compressed images, so you can still copy, search, and select text within your PDF.

How much can I really shrink my PDF file size?

The reduction can be extreme, especially for image-heavy documents. Files over 100MB can often be reduced to just a few hundred KB, making them much easier to share by email or host online.

Compress PDF Lite: Maximum PDF Compression

Why Use Our Compress PDF Lite Tool?

When you need the smallest possible file size, our Compress PDF Lite tool delivers. Using an advanced PDF-to-Image method, this tool can reduce pdf size dramatically, turning huge 100MB files into easily shareable 200KB documents. It's the ultimate pdf size reducer for large files, and it all happens securely in your browser.

Extreme Compression Technology

This tool works by converting each page of your PDF into a highly optimized image and then reassembling them into a new, incredibly small PDF. This method is perfect for documents heavy with images and graphics, allowing you to shrink pdf size far more than standard compression methods.

Maximum Privacy with Client-Side Processing

Your privacy is our top priority. This tool operates entirely within your web browser. This means your large files are never uploaded or sent to our servers. All compression is performed directly on your own device, making it the most secure way to compress pdf file online.

Selectable Text Preservation

Unlike other tools that use this method, our pdf file compressor is unique: it preserves a selectable text layer. This means that even after extreme compression, you can still search for text and copy-and-paste content from your PDF, giving you the best of both worlds—tiny file size and full usability.

Simple Quality Controls

Easily balance size and quality. Choose "Standard Quality" and use the slider for fine-tuned results, or select "Extreme Compression" when you need the absolute smallest file possible.
