Merge, Split & Rotate PDF — No Upload

Combine, split, and rotate PDFs on your own machine — no watermark, no login.

Merge / Split / Rotate on-device · nothing uploaded

Combine several PDFs into one, in the order you add them.

    How it works

    Add your files and the edit runs in your browser with the open-source pdf-lib library, which loads the first time you use it. The new PDF is built locally and handed back as a download — your original is untouched, and nothing is sent to a server.

    And that's rather the point: contracts, IDs, medical forms, and bank statements are exactly the documents you shouldn't be handing to an ad-funded website. No upload, no watermark on the result, no account wall.

    Merge, split, rotate

    Merge joins files in the order you add them. Split pulls a page range (say 3–7) into its own document. Rotate turns every page 90°, 180°, or 270° — handy for anything scanned sideways.

    Add this tool to your site

    Paste it anywhere. It runs in your visitor's browser, so no files ever touch your server — nothing for you to host, store, or worry about.

    Questions

    Is there a watermark or page limit?

    None of the above — no watermark, no page limit, no account. Most "free" PDF sites slap on a watermark or cap how much you can do in a day; this runs on your machine, so there's nothing to meter.

    Are my documents uploaded to a server?

    No. It all happens in your browser with the pdf-lib library running locally, so sensitive contracts, IDs, and statements never leave your device.

    What can I do here?

    Merge several PDFs into one, pull a page range out into its own file, or rotate pages in 90° turns. Each action hands you back a fresh PDF.
