How to merge PDF files online (free, no watermark)

Merging PDFs is one of the most common document tasks: combining invoices into a single file, stitching together scanned pages, or assembling a report from several exports. Doing it manually by printing and re-scanning is slow and lossy. A proper merge keeps the text selectable and the quality intact.

1. Open the Merge PDF tool and drop in two or more PDF files.

2. Drag the files to set the order you want them combined in.

3. Click Merge — the files are processed on our secure backend and combined into one document.

4. Download the result. Files are automatically deleted within an hour for guests, 24 hours for signed-in users.

Your files travel over an encrypted connection, are processed in an isolated worker, and are deleted automatically. We never sell or share uploaded content. For maximum privacy on smaller tasks, many of our other tools run entirely in your browser and never upload anything at all.
