How to Merge PDF Files for Free

Merging multiple PDF files into a single document is one of the most common document tasks. Whether you're combining chapters, reports, or scanned pages, Doclair makes it instant and free.

Unlike most online PDF tools, Doclair processes your files entirely in your browser. Nothing is uploaded to any server — your files stay on your device.

Step 1: Navigate to the Merge PDF tool and click "Choose PDF Files" or drag your files into the drop zone.

Step 2: Reorder your files by dragging them up or down in the list. The final PDF will follow this exact order.

Step 3: Click "Merge PDFs" and your browser will combine the documents.

Step 4: Click "Download" to save your merged PDF. No watermark is added.

How many files can I merge? Up to 50 PDF files per merge, limited only by your device's memory.

Can I merge PDFs on mobile? Yes. Doclair works in Safari on iPhone and Chrome on Android.

Is it safe for confidential documents? Absolutely. Since no upload occurs, even sensitive legal or medical documents can be safely merged.
