Frequently Asked Questions
Is my data safe when merging PDFs?
Absolutely. All merging happens entirely in your browser using JavaScript. Your PDF files are never uploaded to any server.
Is there a file size limit?
There is no hard limit — it depends on your device's memory. Most modern browsers can handle hundreds of megabytes without issues.
Can I merge password-protected PDFs?
No, encrypted or password-protected PDFs cannot be processed. Remove the password protection first using your PDF reader.
Does the order of files matter?
Yes. The final PDF will contain pages in the order the files are listed. Use the up/down arrows to reorder before merging.
What browser is supported?
All modern browsers are supported: Chrome, Firefox, Safari, and Edge. No plugins required.
