Frequently asked questions
Is merging PDFs really free?
Yes. Merging is completely free with no limits, no signup, and no watermark on the merged document.
Will merging change the quality of my PDFs?
No. Pages are copied exactly as they are — text, images, and formatting are preserved without re-rendering, so quality stays identical.
Are my PDFs private?
Yes. All merging happens locally in your browser. Your files are never uploaded to any server.
How many PDFs can I merge at once?
There is no set limit. You can merge as many files as your browser's memory comfortably handles — for very large batches, merge in groups if the page feels slow.
