How to Use OCR for Receipts and Invoices — Digitize Your Expenses

If you've ever stared at a pile of crumpled receipts at tax time, OCR can save you hours of manual data entry. Here's how to use OCR to digitize receipts and invoices effectively.

Why Use OCR for Receipts?

• Save time — No more typing out line items manually
• Reduce errors — OCR is more accurate than manual transcription
• Go paperless — Digitize and archive receipts for tax and accounting
• Expense tracking — Copy extracted text into spreadsheets or expense software

Step-by-Step: Extract Text from a Receipt

1. Photograph the receipt — Use your phone camera. Flat, well-lit photos work best.
2. Upload to Snap2Txt's Receipt OCR — Paste from clipboard or upload the image file.
3. Enable preprocessing (optional) — If the receipt is faded or crumpled, try:
   • Contrast enhancement — Makes faded text more readable
   • Binarization — Converts to black and white, which can help with colored receipts
   • Sharpening — Helps with slightly blurry photos
4. Click "Extract Text" — The OCR engine will process your receipt.
5. Copy the text — Paste into your spreadsheet, accounting software, or note-taking app.

Tips for Difficult Receipts

Crumpled Receipts

• Flatten the receipt as much as possible before photographing
• Use contrast enhancement + sharpening preprocessing
• If the text is on thermal paper that's fading, photograph it ASAP — the ink degrades over time

Faded Receipts

• Use binarization (black and white) preprocessing
• Increase brightness on your phone camera before taking the photo
• Contrast enhancement can bring out faint text

Multi-Language Receipts

• Travel receipts often mix languages (e.g., a Japanese receipt with English brand names)
• Use an OCR tool with auto-detection like Snap2Txt — it handles multiple languages in a single image

Receipt OCR vs. Dedicated Expense Apps

Dedicated expense apps (Expensify, Receipt Bank) offer structured data extraction — they identify merchant name, date, total amount, and line items automatically. However, they typically require a paid subscription.

Free OCR tools like Snap2Txt extract all the text as-is. You then copy and paste the relevant information into your preferred tool. For occasional use, this is often faster and cheaper than subscribing to a dedicated app.
