OCR works best when the scan is clear. Small changes in scan quality can make a big difference to how accurately text is recognized.

When this workflow matters

This workflow matters when a document must be clear, complete, easy to review, and ready for upload or sharing. It is especially important for tenders, compliance packs, contracts, reports, finance documents, and business records where small mistakes can delay approval.

A practical way to prepare the file

Use straight, well-lit scans with enough resolution. Avoid shadows, curved pages, low contrast, handwritten notes over text, and photos taken at an angle.

Quality checks before you send it

After OCR, search for names, numbers, and key phrases. If recognition is poor, clean or rescan the document before relying on extracted text.
