About Split PDF in Half

Split a PDF in half when every page needs to be separated into two matching sections rather than extracted by page number. This local browser tool takes one PDF and creates two new PDFs in the same page order. Choose a vertical split to make a left-half file and a right-half file, or choose a horizontal split to make a top-half file and a bottom-half file. Each output contains one half of every original page, so a ten-page source becomes two ten-page downloads. That is useful for digitized book spreads, two-column handouts, wide scanner captures, side-by-side forms, proof sheets, and documents that need to be printed or reviewed as separate halves. It is deliberately different from splitting a PDF by page ranges: the original page count stays the same in each download, while the visible area of every page is divided along its centre line. It is also different from Crop PDF. Crop PDF changes the visible box of one document; this tool creates two complete, separately downloadable PDF sequences with their own smaller page dimensions. The source page artwork is embedded into a fresh PDF page and clipped to the selected half, so the other half cannot show outside the new page boundary. No source file is uploaded, no account is required, and the original PDF is never overwritten. The file is read and processed on your device, then the two downloads are created in your browser. Choose your direction, run the split, and save the left and right files or the top and bottom files individually. This avoids a ZIP archive and lets you use either result immediately. Normal PDF page artwork, including text, vectors, and images, is rendered into the new page. The original page is not edited in place and this tool does not claim to remove hidden content from the source file. Interactive objects are a different layer of a PDF, so fillable form fields, comments, links, buttons, and annotations are not retained as editable objects in the half-page output. Use a full PDF editor when that interactivity must survive. Password-protected or unreadable PDFs are rejected safely; remove known protection before trying again. Some scans and document feeders store a 90-degree or 270-degree page rotation. The tool detects those pages and shows a notice because the split is calculated in stored PDF coordinates. In a viewer, a vertical split may therefore appear as a top-and-bottom visual boundary, or the reverse. Always open the two downloads and inspect the boundary before sending a rotated document to print. For ordinary, unrotated reports and scans, the left/right or top/bottom labels match the page as displayed. Use Split PDF when you want page-range files, Rearrange PDF Pages when you need a new order, Crop PDF when you need custom margins, and Rotate PDF when the task is only orientation. Split PDF in Half is best when every page follows the same two-panel layout and you need two clean, private, usable outputs in original order.

Methodology & sources

For each source page, the tool creates a new half-sized page, embeds the complete original page, shifts it to expose the requested side, and applies a matching PDF clipping path. It creates one ordered PDF for the first half and another for the second half.

Frequently asked questions

Does this split pages or split a PDF by page number?
It splits the visible area of every page at its centre. Both downloads keep the original page order and page count.
Will I receive two files?
Yes. A vertical split creates left and right PDF files; a horizontal split creates top and bottom PDF files.
Are my PDF pages uploaded?
No. The source and both downloads are processed locally in your browser.
What happens to forms, comments, and links?
The page artwork is retained, but interactive PDF objects are not preserved as editable objects in the half-page outputs.
Why does a rotated page look different from the selected direction?
The split follows stored PDF coordinates. A page saved with 90 or 270 degrees of rotation can make a vertical coordinate split look horizontal in a viewer.
