Frequently Asked Questions

How does the compression work?

We use sophisticated algorithms to remove redundant PDF objects, compress metadata, and optimize internal streams without altering your visible text or layout.

Is 'Extreme' compression safe?

Yes, it's completely safe. However, in documents with high-resolution images, you might notice some slight softening of details. For standard text documents, it's virtually indistinguishable from the original.

Can I undo the compression?

Compression is a one-way process that creates a new file. You will always keep your original original file on your computer; we just help you create a smaller version of it.
