How to merge PDF files

- Use the up and down arrows to set the order; remove a file with the ✕ button.
- Click “Merge PDF” and download the resulting merged.pdf.
Tips
Pages appear in the final document in the same order as the files in the list, so check the order before merging. The list shows each file's size and page count, which makes it easy to confirm nothing is missing.
If you only need some pages from a document, extract them first with the PDF splitter. Photos can be turned into PDFs before merging.
Limitations
Password-protected (encrypted) PDFs are not accepted – remove the protection in the original app first. Corrupt files are rejected with a clear message. Interactive form fields and bookmarks may not carry over, but the page content is unchanged.
Privacy
Merging happens in your browser, in your device's memory. Files are not sent to any server, so confidential documents can be combined safely.
