Question 1

Does compressing a PDF reduce its quality?

Accepted Answer

Our PDF compressor offers multiple compression levels so you can balance file size and quality. The default setting significantly reduces size while maintaining excellent visual quality for most documents. Your files are processed entirely in your browser and never uploaded to any server.

Question 2

What is the maximum file size I can compress?

Accepted Answer

Since all compression happens directly in your browser, the maximum file size depends on your device's available memory. Most modern devices can handle PDFs up to 100 MB or more without issues. Your files are processed entirely in your browser and never uploaded to any server.

Question 3

How does client-side PDF compression work?

Accepted Answer

Our tool uses advanced browser-based algorithms to optimize images, remove redundant data, and streamline the PDF structure — all within your browser. No internet upload is required, making it fast and private. Your files are processed entirely in your browser and never uploaded to any server.
