Frequently Asked Questions
Is there a limit to how many PDFs I can merge?
No hard limit. You can merge as many PDFs as your browser memory allows. Very large merges (100+ files) may be slow.
Will the merged PDF keep bookmarks?
Basic page content is preserved. Bookmarks and interactive form fields may not carry over in this version.
Are my files uploaded to a server?
No. All processing happens in your browser. Your documents never leave your device.
