Frequently asked questions
Is it really free?
Yes — merging PDFs is completely free, with no signup, no watermark, and no daily limits.
Are my files uploaded to a server?
No. The merge happens entirely inside your browser using your device, so your documents never leave your computer.
Is there a limit on how many PDFs I can merge?
You can merge as many PDFs as your device can comfortably handle. Everything is processed locally.
Can I reorder the files before merging?
Yes. Use the up and down arrows to arrange the files in the exact order you want before merging.
Will the quality change?
No. Pages are copied as-is, so text stays selectable and quality is preserved.
