About this tool

Merge PDF Online lets you combine PDF files without installing software or creating an account. Drag in your documents, set the page order, and download a single merged PDF. Everything runs locally in your browser, which is ideal for contracts, invoices, and study packets you do not want to upload. Pair it with our PDF split or rotate tools if you need to tidy pages before merging.

How to use

  1. Add two or more PDF files from your device.
  2. Arrange file order before merging if sequence matters.
  3. Click merge and wait for client-side processing.
  4. Download the combined PDF and verify page order.

Understanding the result

  • Output page count equals the sum of pages in all inputs unless pages were excluded.
  • File order in the list determines page sequence in the merged PDF.
  • Bookmarks and form fields from sources may not all carry over—check interactive PDFs.
  • Very large merges depend on device memory; split and merge in batches if needed.

FAQ
