Cách sử dụng Split PDF in Half
Slice each selected PDF page vertically or horizontally into two separate pages.About split PDF pages in half
Slice each selected PDF page vertically or horizontally into two separate pages. Turn scanned book spreads, A3 booklet sheets, or two-up receipts into clean single-page sequences for reading on phones, tablets, or e-readers.
Splitting adjusts the page boundary boxes along the exact midpoint (50%) of the page width or height. Content that crosses the center gutter will appear clipped at the split line.
How PDFolio helps you split PDF pages in half
PDFolio clones each target page twice in memory and sets distinct CropBox and MediaBox boundaries for each half, keeping vector text and embedded graphics completely lossless.
If you want to trim margins around a single page rather than divide it into two pages, use Crop PDF. If you want to break a multi-page PDF into separate files, use Split PDF.
Before you download
Choose Right-to-Left reading order for manga or RTL language scans when splitting vertically.
When the result is ready, download it immediately and open it in your usual PDF viewer to make a final check. You can then use Clear task data to release temporary file references from this browser tab. PDFolio does not create an account, cloud folder, or server-side document history.
A private way to split PDF pages in half
PDFolio handles the selected files in the active browser tab. A Web Worker on your device performs the PDF task so the interface can remain responsive; document bytes are not sent to a PDF processing server, upload queue, account database, or advertising platform.
Các bước
- Add a PDF with double-page spreads or 2-up scans.
- Choose Vertical (left and right halves) or Horizontal (top and bottom halves) and reading order.
- Select specific pages or leave empty for all pages, then process and download.
Nên biết: Unselected pages are kept intact so you can leave single-page covers untouched while splitting interior spreads.
Câu hỏi thường gặp
Does splitting a PDF page in half reduce text quality?
No. PDFolio duplicates the vector page geometry and adjusts the page boundary boxes without rasterizing text.
Can I keep the cover page intact and only split the inside pages?
Yes. Deselect page 1 in the page preview or enter range 2-last before processing.
Does split PDF pages in half change my original file?
No. PDFolio creates a new file for download. Your source file remains unchanged on your device.
