What happens to your files?

Browser-based PDF processing means the work happens on your own phone or computer, rather than sending the document to a remote processing service.

Choosing a file is not an upload

When you select a PDF in PDF Tools Club, your browser gives the page access to that selected file. Our tools read it in memory, perform the requested operation and prepare a download locally.

Why there are limits

Your device supplies the memory and processing power. A 50 MB input cap is a useful starting limit, but very complex pages can still exceed available resources. Smaller files generally work better on mobile.

After you finish

Save the result to your device. Closing the tab releases the current workspace; the site does not keep a server-side copy. Your original file and downloaded result remain wherever you saved them.
