Merge PDF
Combine multiple PDFs into one file.
Input: Multiple PDFs
Drop two or more PDF files to start merging in order.
Server processing: file is uploaded, processed, then deleted.
Accepted: PDF. Add at least two files. Merges follow the order shown below, and large combined selections can still fail in the browser. Large PDFs may fail on phones or low-memory devices.
Merge multiple PDFs
Upload two or more PDF files, check the order, and merge them into one output.
Start by selecting at least two PDF files.
- Review file order before export.
- Remove files you do not need.
- Add more files anytime before merge.

How to use
The Merge PDF tool combines two or more PDF documents into a single file directly in your browser. No software to install, no account required — your files never leave your device.
- Add your PDF files
Click the file input or drag and drop your PDFs onto the upload area. You can add as many files as you need.
- Check the order
Files are merged in the order they appear in the list. Review the sequence before proceeding — the first file listed becomes the first section of the merged document.
- Click Merge
Press the Merge button to combine the PDFs. The browser processes everything locally, so no data is sent to a server.
- Download the result
Once merging is complete, click the download link to save your combined PDF. The result preserves the original formatting, fonts, and page sizes from each source file.
Tip: For very large combined selections (over 100 MB total), consider splitting the task into smaller groups to avoid browser memory limits.
