Frequently asked questions
Is this PDF merger free?
+
Yes, completely free with no limits on how many PDFs you combine or how often you use it. No account, no watermark.
Are my PDFs uploaded to a server?
+
No. Merging happens entirely in your browser using pdf-lib. Your files never leave your device — there's no server upload and nothing is stored.
How many PDFs can I merge at once?
+
There's no fixed limit — add as many files as you need. Very large batches may take a few extra seconds to process depending on your device.
Can I change the order of the merged pages?
+
Yes. Drag any file's thumbnail to reorder it before merging. Each PDF's own internal page order is kept intact.
Will merging affect the quality of my PDFs?
+
No. Pages are copied directly from the source files, preserving the original text, vector graphics, images, and fonts exactly.
Can I remove a file after adding it?
+
Yes. Hover over any file card and click the X to remove it from the merge before combining.
