Split PDF in Half

Archivists and students often scan open books as a single wide page showing left and right spreads together. Split in Half cuts down the middle (or at a custom vertical line) so each physical page becomes its own PDF for reading on phones or e-invoice portals.

Siliph Split in Half processes each page in the browser pipeline with encrypted uploads, detecting the gutter automatically on consistent scans or letting you nudge the split line when lighting varies. Output order follows reading sequence: left then right, top to bottom.

The tool preserves resolution on each half, which keeps small footnotes legible after separation. This is preferable to cropping manually in an image editor and reassembling PDFs by hand.

Files purge within two hours on the free tier, and no signup is needed for a quick split job. Works well after Deskew PDF when camera captures were slightly tilted before halving.

Combine with OCR PDF when the split pages must become searchable text for citation or full-text search in a document management system.

Siliph split tools divide PDFs by range, bookmark, size, or text trigger entirely in the browser with encrypted transfers at each step. Generated parts are auto-deleted within two hours on the free plan, and splitting starts immediately without signup.
