Compress PDF FAQs

Common questions about compressing PDFs securely.

How does Tuko compress PDFs without uploading them?

We use WebAssembly to run a powerful PDF engine directly inside your web browser. This means your files are processed locally on your device's memory, guaranteeing that no sensitive data is ever sent to a server.

Is there a risk of my compressed PDF being read by third parties?

No. Since the compression happens entirely on your own device without any uploads, it is impossible for third parties or even us to access or read your files.

Does compressing reduce the quality of my PDF?

Our 'Smart' mode only compresses the images inside the PDF while preserving the original crispness of text and vector graphics. The 'Maximum' mode performs stronger compression but may slightly lower the overall visual quality.
