Merge PDF

Combine selected PDF documents in the order you choose.

How to use this tool

Add at least two PDFs. Use the arrows to choose their order, then merge and download the result. Each file’s pages stay in their original order.

Your PDFs stay in this browser. They are not uploaded to DoableLab or an external service.

Pages, website and internal links, bookmarks, supported editable forms and ordinary comments/highlights are preserved. Field names are grouped by source document to prevent conflicts. The result is a new unsigned PDF. Attachments, multimedia, accessibility tags and script/file-launch actions are not retained. Encrypted PDFs and unsupported forms are rejected.

2–20 PDFs · 40 MB combined · 800 pages total · 40-second processing limit.
