About PDF merge
Combine multiple PDF files into a single document without uploading anything. Reorder files before merging so pages appear in the order you need.
How it works
Dockzio copies pages from each PDF into a new file using pdf-lib in your browser. The original files stay on your device.
Limits
You can merge up to 20 PDFs at a time, with each file up to 25MB. Password-protected PDFs are not supported yet.
Page order
Use Move up / Move down to set the merge order. The first file in the list becomes the start of the merged PDF.
Privacy first
Everything is processed locally in your browser. Your documents are never sent to a Dockzio server.
