Merge PDF without uploading
Your files are combined by code running in this browser tab, so you merge PDF locally. Nothing is sent to a server, so there is nothing to leak, log or delete later.

Questions people ask
Is this a safe merge PDF tool?
Yes. Most online mergers upload your files to their servers first. Here the merge runs locally in your browser, so the files never leave your device — you can confirm it in your browser's network tab while merging.
Can I combine PDF confidential files, like contracts or medical records?
Yes, and that's what it's built for. Because nothing is uploaded, confidential documents never reach a third party's server.
Can I combine PDF single-page local files into one document?
Yes. Drop in each single-page PDF saved on your computer — individually scanned pages, for example — and they're combined into one multi-page file in the order you set.
Is there a limit on how many PDFs I can merge?
No artificial limit. In practice you're bound by your device's memory — most laptops handle dozens of files without issue.
Will the merged file have a watermark?
Never. What you add is what you get back, just combined.
Can I merge password-protected PDFs?
Not directly — remove the password first, then merge.
