Frequently Asked Questions

Are my uploaded PDF files sent or processed on your servers?

Never. All PDF processing happens directly on your device. Files never leave your browser, so none of your document metadata or pages are ever uploaded or saved on any server.

What is the limit on file sizes or page counts for merging files?

Since compiling is handled in-browser using your local hardware RAM and CPU threads, there is no artificial platform boundary. You can merge files consisting of hundreds of pages or several megabytes without any premium restrictions.

Can I reorder or rearrange documents before executing the merge?

Yes, absolutely. Once you drag or select two or more files, you can use the Up and Down arrow buttons next to each item in the workspace listing to instantly define your custom compilation order, or delete unwanted documents with the delete button.

Does this tool support password-protected or encrypted PDFs?

Due to secure client-side sandbox constraints, this tool cannot read or decrypt password-protected files. Password protection must first be removed from any encrypted file before attempting to load or merge it.
