CodeASystem PDF tools
Merge PDFs, right in your browser.
Add your PDFs, arrange them in the order you want, then download one combined file. Your documents stay on your device.
Merge PDFs
Add two or more files, put them in order, then download one PDF.
Your files stay in this browser tab. They are not uploaded to CodeASystem.
How it works
One document, in your chosen order.
This tool copies the pages from each selected PDF into a new file. It is intended for ordinary, unlocked PDFs. Check the downloaded file before sharing or relying on it.
