Split PDF in Half

About the Split PDF in Half

Some PDFs are really two documents in one — a scan of a double-page spread, or a file where the first half and second half belong apart. Splitting it exactly down the middle saves you counting pages and typing ranges.

This Split PDF in Half tool divides a document into two equal parts in a single click, right in your browser. Quality is preserved and nothing is uploaded, so it is both fast and private.

How to use the Split PDF in Half

1. Add your PDF by dragging it in or clicking to browse.
2. Click "Split in Half" to divide it on your device.
3. The document is split into two equal parts.
4. Download both halves.

Key features of the Split PDF in Half

How the Split PDF in Half works

This tool works directly with the internal structure of your PDF using established open-source engines (pdf-lib and PDF.js) that implement the ISO 32000 PDF specification. Everything runs locally in your web browser through JavaScript, which means the document is read, modified and re-saved on your own device — it is never transmitted to a server. That is what makes the process both instant and genuinely private.

Because the pages are handled at the object level rather than being re-printed, text stays selectable and sharp and images keep their original quality unless you deliberately choose to compress them.

Tips & best practices

• If the document has an odd number of pages, the split simply puts the extra page in one half.
• For a precise split at a specific page, use the Split PDF tool with a custom range instead.
• Recombine later at any time with the Merge PDF tool if you change your mind.

Standards & accuracy

Built on the PDF (ISO 32000) standard and processed entirely in your browser, so files are never uploaded.

Because processing happens locally, results are consistent and repeatable. For scanned PDFs (images of text with no selectable text layer), text-based operations require OCR first — the tool works with the document's existing text layer.

There is no signup and no account, so you can use it as often as you like while keeping full control of your information. This makes it a safe choice even for confidential and sensitive work.
