PDF OCR tips: pages, clarity, and mode choice
Why short scans work better, when to force OCR, and common accuracy pitfalls.
Too many pages or huge resolutions will slow the browser — split the PDF first.
Clear print and high contrast scan better; skew, shadows, and handwriting struggle.
Use Auto for digital PDFs; Force OCR for pure scans or garbled text layers.
Pick Chinese+English for mixed docs; English-only for Latin text to reduce noise.
