Frequently Asked Questions

How many PDF files can I merge at once?

You can merge as many PDF files as your browser's memory allows. For the best experience, we recommend merging up to 20 files at a time.

Will merging affect the quality of my PDFs?

No. Merging PDFs simply combines the pages from each file into a single document. There is no quality loss during the process.

Can I reorder the files before merging?

Yes. After uploading your files, you can use the move up and move down buttons to arrange them in any order before merging.

Are my files safe when merging?

Absolutely. All merging is performed locally in your browser using pdf-lib. Your files are never uploaded to any server.
