Does merging PDFs reduce the quality of my documents?

No. Merging simply concatenates the pages from each file into a single PDF. Text, images, and formatting remain identical to the originals.

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

You can merge up to 20 PDF files in a single operation, with each file up to 50 MB. For most everyday tasks this is more than enough.

Are my files uploaded to a server?

No. All processing runs entirely in your browser. Your files are never uploaded, stored, or shared with any server.
