Batch OCR: Processing Multi-Page Scanned Documents

Quick answer: Run OCR across a folder of scans with a repeatable queue and a quality-control pass that actually catches bad pages. Open 图片 OCR — everything runs locally in your browser, and files never leave your device.

Steps

1. Normalize filenames first (001_contract.pdf) so the queue order is deterministic.
2. Upload in batches of 10–20 files with the same language setting.
3. Spot-check the first and last page of every batch — blurred or skewed strays are the classic failure.
4. Export results under matching names and archive.

Important notes

• Mixed-language batches need the combined language mode; a wrong language setting ruins an entire batch.
• Batching amplifies bad input — one dark scan hides in a queue; inspect thumbnails before committing.

Common questions

Can accuracy be measured automatically? Not without a ground truth — sampled manual review is the practical QC.

A batch died halfway — redo everything? No; compare finished filenames against the source list and resume from the gap.
