Privacy & File Safety
4 questions
Are my files safe and private?
Yes. Many tools process files locally inside your browser using JavaScript, meaning your documents never leave your device at all. For tools that require server-side processing, files are handled securely and deleted immediately after processing.
Does ClearPDFs read or store my documents?
No. We do not read, analyse, or permanently store your files. Files processed locally in your browser never touch our servers. When uploads are temporarily required, they are deleted right after processing and are never shared with third parties.
Do you sell user data or files?
Never. We do not sell, share, or monetise your files, personal information, or usage data. Your documents are yours and yours alone. We are funded through display advertising only — not data.
Is my connection to ClearPDFs secure?
Yes. All pages on ClearPDFs are served over HTTPS with SSL encryption. Your connection is always secure, whether you are uploading a file or simply reading a tool page.

Using the Tools
3 questions
Is there a file size limit?
Most tools support files up to 100MB. Since many tools process files directly in your browser, performance depends on your device's speed and available memory. For the best experience, we recommend keeping files under 50MB.
Why is ClearPDFs so fast?
Many of our tools process files directly in your browser using modern JavaScript libraries — no round-trip to a server needed. Your file is processed on your own device and the result is ready almost instantly, typically in under 3 seconds.
A tool isn't working — what should I do?
First, try refreshing the page and using a different browser — Chrome or Firefox usually work best. Make sure your file is not corrupted or password-protected. If the issue continues, please contact us with the tool name, your browser version, and a description of the problem.
