How to merge PDF files
Add two or more PDFs using the box above, reorder them with the up/down arrows until they are in the order you want, then click Merge. Your combined PDF downloads instantly. Because the merge runs in your browser, your files are never uploaded and there is no limit on file count or size beyond your device's available memory.
Frequently asked questions
- Is there a limit on how many PDFs I can merge?
- No. You can combine as many PDF files as your device has memory for. There are no daily caps because everything runs locally in your browser.
- Will merging change the quality of my PDFs?
- No. Pages are copied exactly as-is, so text stays selectable and images keep their original resolution.
- Are my files uploaded anywhere?
- Never. The merge happens entirely in your browser using JavaScript. Your documents never leave your device.
