Frequently Asked Questions

Does compression affect document quality?

Yes, reducing file size inevitably reduces some visual quality. Our “Recommended” setting provides the best balance, keeping text readable while shrinking the file significantly.

Why is the text in my compressed PDF not selectable?

Because client-side processing cannot restructure complex PDF fonts safely, this tool “flattens” the document into optimized images. This drastically reduces size but removes text selectability.

Can I use this tool offline?

Absolutely. Once the webpage has fully loaded in your browser, the compression scripts work locally on your device without needing an active internet connection.
