Frequently asked questions

How many PDFs can I merge?

There is no limit to the number of files you can merge. Because everything is processed locally in your browser, speed depends on your device and file sizes. With dozens of large PDFs it may take a little longer, but there is no technical upper limit.

Is quality preserved after merging?

Yes, completely. Pages are copied unchanged from the source files and joined together. No quality is lost: text remains selectable and searchable, images keep their original resolution, and links and bookmarks are preserved.

What if the PDFs are password-protected?

A PDF that requires a password to open cannot be merged without that password. PDFs with only a copy or print restriction can be merged as long as they load successfully.

What are common reasons to merge PDFs?

Many people merge PDFs for a quote with attachments, a tax return with evidence, scanned documents that were scanned page by page, or a presentation with a separate appendix file. One clean document is easier to share and store.

Are my files uploaded?

No. Everything happens in your own browser. Your file never leaves your device and is not stored anywhere.

Is it free?

Yes, completely free, without watermark or account. The site is paid for by ads.
