Merge PDF
Combine multiple PDF files into one, free and online. Drag, drop, reorder, and download — all in your browser. No sign-up, no watermark, nothing uploaded.
🔒 Your files are processed entirely in your browser — nothing is uploaded.
Combine PDFs without uploading them anywhere
Most “merge PDF” sites upload your documents to their servers to do the work. This one doesn’t. Add your files, arrange the order, and download a single combined PDF — the entire process happens in your browser, so your contracts, statements and private documents never leave your device.
How to merge PDF files
- Add your PDFs — drag and drop them onto the box above, or click to browse.
- Set the order — use the up/down arrows to arrange the files.
- Merge & download — click the button to get one combined PDF.
Why merge in the browser?
- Privacy — sensitive files (tax forms, contracts, medical records) stay on your device.
- Speed — no upload/download round-trip to a server.
- Quality — pages are copied as-is, so text stays selectable and sharp.
It’s free, has no watermark, and needs no account. More PDF tools — split, compress, and image-to-PDF — are on the way.
Frequently asked questions
Is this PDF merger free?
Yes — completely free with no account, no sign-up, and no watermark on your merged file.
Are my files uploaded to a server?
No. This is the big difference from most online tools: your PDFs are combined entirely inside your web browser. They are never uploaded to or stored on our servers, which keeps confidential documents private.
Can I choose the order of the files?
Yes. After adding your files, use the up/down arrows to arrange them. They're merged top-to-bottom in the order you set.
Is there a limit on the number or size of files?
There's no fixed limit, but because everything runs in your browser, very large files depend on your device's memory. For most documents it's fast and smooth.
Will the quality change?
No. Merging copies the original pages as-is, so text stays selectable and quality is preserved.
Does it work on mobile?
Yes — it works in any modern browser on phone, tablet or desktop.
