Frequently asked questions
Is this PDF merger free?
Yes — completely free with no sign-up, no watermark and no limit on the number of files.
Are my PDF files uploaded to a server?
No. The files are merged entirely in your browser — your PDFs never leave your device and nothing is stored on our servers.
Can I choose the order of the files?
Yes. Use the up and down arrows to arrange the files, and they're combined in exactly that order, one file's pages after the next.
Will merging change the quality of my PDFs?
No. Pages are copied across as-is, so text stays selectable and images keep their original quality — nothing is re-compressed.
Is there a limit on file size or page count?
There's no fixed limit. Because everything runs in your browser, very large files are only bounded by your device's memory.
