Merge PDF Files

Free PDF Merger — Combine PDFs Online

Combine multiple PDFs into a single, tidy document. Drag your files, reorder them, and download the merged PDF. Keep original quality with a lossless merge, or normalize pages to A4/Letter when layout consistency matters.

How to merge PDF files

1. Click or drag to add your PDFs.
2. Reorder files using the ↑ and ↓ buttons.
3. (Optional) Choose a Normalize size to make pages consistent.
4. Click Merge PDFs and download your file.

Why merge PDFs?

• Send one document instead of many attachments.
• Package proposals, invoices, or reports together.
• Ensure a consistent reading order across files.

Tip: Keep “Lossless merge” enabled for maximum fidelity. Use Normalize only if recipients need uniform page sizes.
