Is there a limit to how many PDFs I can merge?

You can merge up to 20 PDF files at once with a combined size up to 100 MB. There is no limit on total page count.

Does merging PDFs reduce quality?

No. PQ PDF merges PDFs at the binary level using Poppler. Page content, fonts, images, and bookmarks are preserved exactly — no re-rendering or quality loss occurs.

Can I reorder files before merging?

Yes. After adding files, drag the handles next to each filename to reorder them. The merged PDF will follow that sequence.

About Merge PDFs

Combine up to 20 PDF files into a single document. Upload all files, then drag the thumbnails to set the order before merging. Page structure, bookmarks, and formatting are preserved from each source file. The merged PDF is assembled server-side and immediately deleted after download — nothing is stored.
