Merge PDF
Combine several PDFs into one file.
Runs entirely in your browser. Verify it in your network tab.
What this does
Files are merged in the order you drop them, keeping every page at its original size and quality. Nothing is re-encoded, so the output is lossless.
Limits
- Encrypted or password-protected PDFs must be unlocked first.
- Very large merges are bounded by your device memory, not by an upload cap.
Is this private?
Yes, and you can check rather than take our word for it. Open your browser's network tab and run the tool: your file never appears in it, because there is no server to send it to. The whole site is static files.
