Frequently asked questions
Is there a limit to how many PDFs I can merge?
You can merge up to 50 files at once. Very large documents are limited only by your device's memory because the merge runs locally.
Will bookmarks and form fields be preserved?
Pages, images, text and vector graphics are preserved. Bookmarks (outlines) and interactive form fields are not carried over when pages are combined.
Are my files uploaded to a server?
No. Merging runs entirely inside your browser using WebAssembly-free JavaScript. Nothing leaves your device.
