Frequently Asked Questions
Is there a file size limit?
There is no strict server-imposed limit because everything is processed on your device. However, browser memory limits may affect combining dozens of massive files (e.g., above 300MB).
Will my merged PDF have a watermark?
No! Provide the ultimate free utility is our goal. We do not insert watermarks on any of the output PDFs.
Is it safe for confidential documents?
Yes. Because the PDFs are merged using a local JavaScript library in your active browser session, your sensitive files are never uploaded to any cloud server.
