FAQ
Questions answered
Is there a limit on how many PDFs I can merge?
You can merge up to 20 PDF files at once. Since everything runs in your browser, performance depends on your device and the size of the files.
Will merging reduce the quality of my PDFs?
No. The tool copies pages directly without re-encoding, so the output quality is identical to the original files.
Do you store or upload my files?
No. Your files never leave your browser. All processing happens locally on your device using JavaScript. We have no server-side component for file handling.
Can I change the page order after merging?
You can reorder files before merging by dragging the thumbnails. If you need to reorder individual pages, try our Reorder PDF Pages tool.
