Frequently asked questions

Is it safe to merge PDFs with PDFCart?

Yes. Files are processed locally in your browser with JavaScript and are never uploaded to any server.

How many PDFs can I merge at once?

Will merging reduce the quality of my PDF?

No. Pages are copied as they are, so text, images and links keep their original quality.
