Visit ocr.space → Click Choose File → Select your image.
Tick the language dropdown (e.g., English + Hindi for multilingual docs).
Step 3 — Click “Start OCR” & Download Result
Within seconds, you’ll see plain text. Copy it or hit Download TXT. For tables, choose Download Excel.
7 Pro Tips to Boost OCR Accuracy to 98 %
- Use 300 dpi scans instead of low‑resolution photos.
- Pre‑crop margins so the tool focuses on text only.
- B&W / Grayscale improves contrast.
- Avoid shadows & folds on the page.
- Select correct language(s) before processing.
- Enable “Deskew” if the tool supports it.
- Post‑edit with spell‑check; no OCR is 100 % perfect.
What About Handwriting?
Free online tools often struggle with messy handwriting. For better accuracy:
- Try Google Lens on your phone (surprisingly good).
- Use EasyOCR locally (Python). See my demo tool: Handwriting → Text.
- Write in clear block letters if possible.
