英语技术说明
20 MiB, 200 pages and 500,000 extracted characters. Digital text only; no OCR or images. Encrypted PDFs unsupported. No automatic heading, list or table reconstruction; fonts, columns and text order require review.
Page headings and Markdown hard line breaks are optional. Source punctuation is escaped as literal text. Empty pages are identified without inventing text. Two-column order splits at the fixed midpoint in the main text direction; full-width headings and unequal columns may need correction. Mixed orientations fall back to PDF text order. Rotations and visible page bounds are considered, but text crossing a crop boundary can include cropped characters. Copy/download uses your current edits; restore returns the original extraction. Documents stay in the browser.
Extract a two-column report, compare reading orders, correct headings manually and download the edited Markdown.
