How it works
Add the PDFs you want to combine, drag them into the right order, and click Merge. The files are stitched together on your device using an in-browser PDF engine — nothing is sent anywhere.
The merged PDF keeps every page exactly as it was; no re-compression or quality loss.
Why merge in your browser
Most online PDF mergers upload your documents to their servers. For contracts, statements and anything confidential, that's a real privacy risk. Here the work happens locally, so your documents stay yours.
It's also faster for large files — there's no upload wait and no download of the result from a remote server.
Ordering and page count
Each file shows its page count so you can confirm what you're combining. Use the up and down arrows to set the final order before merging.
You can merge as many files as your device's memory allows — there's no arbitrary file-count cap.
Frequently Asked Questions
Are my images uploaded to a server?
No. Every conversion runs locally in your browser using your device's own processor. Your images never leave your computer or phone, and nothing is stored on our servers.
Is there a watermark or page limit?
No watermark and no page limit. The tool is free and adds nothing to your document — the merged PDF contains only your pages.
Can I reorder the files before merging?
Yes. Each file has up/down controls so you can arrange them in exactly the order you want the final document to follow.
Will merging change the quality of my PDFs?
No. Pages are copied as-is into the new document, so text stays sharp and selectable and images are untouched.
Is it free, and are there limits?
It's completely free with no account required. Because processing happens on your device, there's no per-file upload limit — the practical ceiling is your device's available memory. You can batch many files and download them as a single ZIP.
