Are all these PDF tools really free?
Yes, every single tool on this page is 100% free. No account, no subscription, no hidden fees. We support the service through non-intrusive advertising.
Do my files get uploaded to a server?
No. All processing happens directly in your browser using JavaScript. Your files never leave your device — they are not transmitted to any server.
Is there a file size limit?
Since processing is done locally in your browser, the limit depends on your device's memory. Most modern devices handle PDFs up to 100–200MB without issue.
Can I use these tools on mobile?
Yes. All tools are fully responsive and work on iPhone, Android, and tablet browsers. No app installation required.

What browsers are supported?
All modern browsers: Chrome, Firefox, Safari, and Edge. We recommend keeping your browser up to date for best performance and compatibility.
Can I process password-protected PDFs?
For most tools, you need to remove the password first using our Unlock PDF tool. Once unlocked, the file can be processed by any of our other tools.
Is Cloud PDF App GDPR compliant?
Yes. Since we never receive or store your files, there is no personal document data to protect. See our GDPR and Privacy Policy pages for details.
