Prepare the source and define the result
Capture the page parallel to the camera, keep all edges visible and avoid fingers, shadows and patterned surfaces. Re-photograph blur instead of inventing detail with filters.
Set acceptance criteria before processing: expected pages or records, languages, critical fields and destination format.
Use a reviewable OCR workflow
Correct perspective conservatively and keep seals, signatures and margin notes inside the crop. Improve contrast only enough to separate text from paper.
Keep recognition evidence beside the source. Confidence prioritizes review but does not guarantee a word or number.
Verify before using the output
Compare names, dates, punctuation, 0/O and 1/I. Test selection alignment at top, center and bottom because perspective errors grow near edges.
Keep the original until the reviewed derivative is accepted. Valid structure does not prove semantic accuracy.
- Filters cannot reconstruct clipped characters.
- Automatic crop can remove margin notes and page numbers.
Put the workflow into practice
Arrange source documents, select the pages you need, and create one PDF locally in your browser. Review the result before choosing any optional next step.
