PDF TOOL
Merge PDF files online
Combine multiple PDFs into one clean document without sending your files to a processing server.
How to merge PDF files
- Select two or more PDF files.
- Check the file order shown below the picker.
- Choose Merge PDFs.
- Your browser creates and downloads one merged PDF.
When this tool is useful
PDF merging is a common last-mile task: combining a signed cover page with a report, joining scanned attachments before sending them, or collecting several exported sections into one file. For small and medium documents, doing this locally in the browser is often faster than uploading each file to a remote service.
Privacy and limitations
The merge operation runs locally in the browser. Large files still consume your computer's memory, and some encrypted or malformed PDFs cannot be opened. Always verify the final page order before sharing an important document.
Frequently asked questions
Do my PDF files get uploaded?
No. This merge tool processes the selected PDF files in your browser. Your documents do not need to be uploaded to our processing server.
Can I choose the order of the PDFs?
Yes. Files are merged in the order shown in the list. In this first version, add them in the order you want before merging.
Why can a PDF fail to merge?
Password-protected, encrypted, damaged or unusually structured PDFs may not be supported by the browser processing library.
