Improved OCR Accuracy
Single pages give OCR engines a clean, unambiguous layout to analyze.
Split PDF for OCR Preparation
Prepare scanned PDFs for accurate OCR by splitting double-page spreads into individual pages. Better page separation means better text recognition.
Why Split PDFs Before OCR?
OCR (Optical Character Recognition) software works best on single-page content. Double-page scans confuse column detection and text-flow algorithms.
Splitting each double-page scan into two single pages before running OCR dramatically improves recognition accuracy, especially for books and journals with two-column layouts.
It also ensures that line breaks, paragraphs, and reading order are correctly identified by the OCR engine.
How to Split a PDF for OCR Processing
Split your scanned PDF into single pages, then feed it into your OCR software.
1. Upload the Scanned PDF
Go to iMZi PDF and upload your scanned document.
2. Split Each Page in Half
Select Vertical split and align the line at the center gutter of your scanned pages.
3. Download Single-Page PDF

4. Run OCR on the Output
Feed the single-page PDF into your OCR tool for superior text extraction results.
Why Pre-Process PDFs Before OCR?
Page splitting is the single most impactful pre-processing step for OCR accuracy.
Correct Text Flow
Reading order and paragraph detection are far more accurate on single pages.
Better Column Detection
OCR column detection works optimally on pages with one logical layout.
Free Pre-Processing
No cost to split — prepare as many pages as you need.
Secure Handling
Your scanned documents are deleted after download.
Works with Any OCR Tool
The output PDF is compatible with ABBYY, Adobe Acrobat, Tesseract, and more.
Better Input, Better OCR Output
Most OCR errors in scanned books come from double-page layouts. Split your PDF first and watch your OCR accuracy improve significantly.
