Frequently Asked Questions
Is this PDF compressor really free?
Yes, it is 100% free to use with no limitations on the number of files you can compress.
Are my files safe?
Absolutely. Your files never leave your device. All compression is done locally in your browser using client-side JavaScript.
Why is my PDF not compressing much?
If your PDF already contains highly compressed images or is mostly text, the size reduction may be minimal. Text-based PDFs are already very small.
Can I compress password-protected PDFs?
No, for security reasons, the tool cannot process password-protected PDFs. Please remove the password first using an unlock tool.
