Frequently Asked Questions

Is there a limit on how many PDFs I can merge?+

No limit. You can merge as many files as your browser's memory allows. Most users merge 2–20 files without any issues.

Will merging PDFs reduce quality?+

No. The merger combines PDF pages directly without re-rendering or re-compressing them, so text, images, and vector graphics remain at their original quality.

Can I reorder pages before merging?+

Yes. Drag the file tiles to set the order before merging. The output PDF follows the order shown on screen.

Can I merge password-protected PDFs?+

The tool requires unprotected PDFs. Remove password protection first using the PDF Password tool, then merge.
