Can I rearrange the order of the PDF files?

Absolutely. After selecting your files, you can use the up and down arrows to arrange them in the exact order you want them to appear in the merged document.

Is there a file size limit for merging?

Because processing happens locally in your browser, the only limit is your device's memory. For most modern devices, you can merge dozens of large PDFs without any issues.

Does merging PDFs reduce quality?

No. Merging PDFs simply combines the existing pages into a new file without altering the original quality or resolution of the content.
