Compress PDF FAQ
How does the compression work?
Each page is re-rendered as an optimized image at the resolution you choose. This dramatically reduces scanned and image-heavy PDFs. Text in the output is no longer selectable, so keep your original if you need to copy text.
What if the compressed file is larger?
Some PDFs, such as text-only documents, are already optimal. If compression would not help, the tool tells you and you can keep the original.
Is the Compress PDF free?
Yes, it is 100% free with no signup, no watermarks and no usage limits.
Are my files uploaded to your servers?
No. Your files are processed entirely inside your web browser and never leave your device. Close the tab and they are gone.
Does it work on phones and tablets?
Yes. The tool works in any modern browser on Android, iPhone, iPad, Windows, Mac and Linux.
