Stays on your device — nothing is uploaded.
How it works
Drop two or more PDF files — they’re combined into one document in the order you add them, with every page preserved exactly. Everything happens entirely in your browser.
Frequently asked questions
- Does this tool upload my files anywhere?
- No. Every PDF is read, created, or combined entirely in your browser. Files never leave your device.
- Is there a file size or page count limit?
- No hard limit from us — the tool runs in your browser, so very large files are limited by your device’s memory rather than a server quota.
- Does merging reduce the quality of my PDFs?
- No — pages are copied as-is, including their original text, images, and vector graphics. Nothing is re-rendered or recompressed.
