Free How to use Invoice OCR
Optical character recognition on DigitalConverter.online uses Tesseract.js and related in-browser OCR engines to recognize characters from images and PDF pages on your device. When you extract text from a receipt, invoice, or scanned document, the recognition model runs locally, which is especially important for documents containing account numbers, government IDs, or financial details. Structured parsers then map recognized text into fields such as totals or passport MRZ lines without round-tripping your scan through a cloud OCR API. Results appear in your browser and can be copied or downloaded without us retaining a copy.
What Invoice OCR does and when to use it
Invoice OCR extracts vendor names, invoice numbers, issue dates, tax amounts, and totals from scanned or photographed invoices for accounts payable, bookkeeping, and ERP import. Small businesses digitize paper vendor bills without manual keying.
Structured fields accelerate reconciliation: matching PO numbers, spotting duplicate invoices, and preparing CSV for accounting software. It complements rather than replaces accountant review for tax compliance.
How this tool works
General OCR recognizes text blocks, then pattern matchers and layout heuristics label fields such as Invoice #, Due Date, and Total. Amount parsing handles currency symbols and decimal separators common in regional formats.
Runs client-side so supplier pricing and tax IDs are not sent to third-party OCR clouds. Accuracy improves on clean PDF scans versus crumpled thermal receipts.
Step-by-step instructions
Upload a clear invoice scan, run extraction, and verify each field against the original. Export or copy structured results into your accounting tool or spreadsheet.
Tips and best practices
Scan at 300 DPI grayscale for consistent line detection.
