Split in half is a free tool that runs entirely in your browser. Two PDFs: first half and second half. It’s ideal for reordering, splitting or combining documents before you send, print or archive them. Because everything happens locally with pdf-lib and pdf.js, your files are never uploaded to a server — Split in half works instantly, even offline, and keeps every document completely private, with no account, no watermarks and no file-size limits.

- 1Open the Split in half tool and drop in your PDF, or click to choose it.
- 2Press Run — there are no settings to fuss with.
- 3Download your result. The whole thing happens on your device, so your PDF never leave your browser.
100% private — nothing is uploaded
Unlike most online PDF tools, Split in half never sends your PDF to a server. Everything is computed locally in your browser with JavaScript, so your documents stay on your device. There's no account, no watermark and no file-size limit — and it even keeps working with your Wi-Fi switched off.
