Why merge PDF files?
Whether you're putting together a tax return, a school report or a portfolio, a single PDF is easier to share, print and archive than a pile of separate files. PDFLabz lets you merge unlimited PDFs in your browser — your files never leave your device.
Step-by-step
- Open the Merge PDF tool.
- Drag and drop your PDFs onto the page (or click to browse).
- Reorder the files by dragging them up or down.
- Click Merge and download the combined PDF.
What makes PDFLabz different
- 100% client-side — files are processed in your browser using
pdf-lib, so nothing is uploaded. - No file size cap beyond what your browser memory allows (usually 100 MB+).
- No watermark on the output, ever.
Tips
- If your PDFs contain forms, merge them in the order you want users to fill them.
- Need to split a PDF instead? Try our Split PDF tool.
- For very large merges, close other browser tabs to free up RAM.
