Frequently asked questions
Is there a limit to how many PDFs I can merge?
You can merge up to 25 files at a time. Because merging happens on your device, very large documents depend on your browser's available memory.
Will bookmarks, links and text stay intact?
Pages are copied exactly, so text stays selectable and page content is unchanged. Document-level bookmarks from the source files are not carried over.
Are my files uploaded?
No. Merge PDF runs entirely in your browser using open-source PDF libraries.
