Merge PDFs

Features

• Reorder files with drag-and-drop before merging so pages end up in the right sequence.
• Page thumbnails let you visually confirm every page before the merge happens.
• Handles large multi-page PDFs by processing them entirely with pdf-lib in the browser.

How it works

1. Drop two or more PDF files onto the tool — each file's pages appear as thumbnails.
2. Drag the files to reorder them and review the page thumbnails to confirm the merge order.
3. Click Merge PDFs to combine them into a single document, then download the result.
