Merge PDF
How to Combine PDF Files into One (Windows, Mac, Phone)
Whether you use a Windows laptop, a MacBook or just your phone, combining PDFs should not need paid software.
A browser-based tool works the same on every device.
On Windows or Mac
Open the Merge PDF tool in Chrome, Edge, Safari or Firefox. Drag the PDFs from File Explorer or Finder into the drop box, arrange them and download.
On Android or iPhone
- Open the tool in Chrome or Safari.
- Tap the drop box and choose PDFs from Files or Downloads.
- Reorder with the arrows.
- Tap Merge & Download – the file is saved to your phone.
Common things people combine
- Scanned pages of one document.
- Monthly invoices for an accountant.
- Label PDFs from different marketplaces.
- Certificates and ID proofs for an application.
Privacy
Many online PDF tools upload your files to their servers. This tool combines them inside your browser, so sensitive documents never leave your device.
After combining
Add page numbers, a watermark or remove extra pages with the other free PDF tools on the site.
Large scans
Phone scans can be several MB per page. If the merged file is too big for email or a portal, convert pages to images at a lower quality and back to PDF, or split the merged file into parts.
Tips
- Rename files with numbers (01, 02…) before adding to keep order easy.
- Add page numbers when combining long documents.
- Remove unwanted pages afterwards with the Remove pages tool.
