Frequently asked questions
Are my PDFs uploaded to a server?
No. The files are merged entirely in your browser using pdf-lib — nothing is uploaded and nothing is stored. Your documents never leave your device.
How do I change the order of the pages?
Each PDF you add appears in a list. Use the up and down arrows to reorder the files before merging — the merged PDF follows that order.
Is there a limit on how many PDFs I can merge?
No artificial limit. You are only bounded by your device’s memory, so very large documents may take a moment to process.
Can it merge password-protected PDFs?
It can open some protected files, but PDFs with strong encryption may fail to load. Remove the password first, then merge.
Is it really free with no watermark?
Yes. Merge as many PDFs as you like, free, with no signup and no watermark added to your document.
