Merge PDF
Combine two or more PDF files into a single document. Everything runs in your browser: the files are never uploaded to a server, there is no file-size quota from us (only your device’s memory), no watermark, and no account.
🔒 100% private — this tool runs in your browser; files are never uploaded.
How it works
- Add your PDFs. Drop two or more PDF files onto the page, or pick them with the file browser. They are read locally — nothing leaves your device.
- Order them. Drag the files into the order you want them to appear in the combined document.
- Merge and download. Click Merge. The combined PDF is assembled in your browser and downloads straight to your device.
Honest limitations
- Encrypted (password-protected) PDFs must be unlocked before merging.
- Very large files are bounded by your device’s memory, since everything runs locally.
Frequently asked questions
Are my files uploaded to a server?
No. The merge happens entirely in your browser using client-side code. Your PDFs never leave your device, which also means there is nothing for us to store, scan, or delete afterwards.
Is there a file-size or page limit?
We impose none. The practical limit is your device’s memory — merging very large PDFs on a low-memory phone can fail, in which case try it on a desktop browser.
Does it add a watermark or require an account?
No watermark, no account, no email. The tool is free and supported by the ads on this page.
Are password-protected PDFs supported?
Encrypted PDFs cannot be merged directly. Remove the password first (you need to know it), or use the full Pyntra editor, which can open encrypted PDFs.
