Ocr AI Tool
How can I use the free online OCR service provided by OCRSpace?
To use the free online OCR service, follow these steps:
- Visit the OCR.space website and go to the online OCR section.
- Upload your image or PDF file in a supported format (.png, .jpg, .webp, or .PDF) or paste the URL of the source file.
- Choose the language for OCR from the available options.
- Optional features you can enable: detect orientation and auto-rotate, auto-enlarge content (recommended for low DPI), and receipt scanning or table recognition if needed.
- Select an OCR engine to use: OCR Engine1 (Default, fastest), OCR Engine2 (fast and very good, also handles special characters like %@$), or OCR Engine3 (extremely good, includes handwriting OCR; may be slower).
- Click Start OCR to begin the conversion.
- After processing, view and download the OCR results as Text or JSON. You can also create a searchable PDF if desired.
The online service is free to use with no registration required, and it supports multi-page documents and multi-column text recognition.
Which OCR languages are supported and how do I choose the best OCR engine?
OCRSpace uses different recognition methods across its engines, and language support varies by engine. The service lists languages such as Arabic, Chinese (Simplified and Traditional), Croatian, Danish, Dutch, English, Finnish, French, German, Italian, Japanese, Korean, Polish, Portuguese, Russian, Spanish, Slovenian, Swedish, Turkish, Ukrainian, Vietnamese, and more. Engine3 emphasizes very broad language support (including many additional languages) and supports handwriting OCR, though it may be slower. Language autodetection is available in OCR Engine2 and OCR Engine3 (not in Engine1).
Tips:
- If you need robust handling of numbers and special characters, try Engine2.
- If you have handwriting or very complex text, Engine3 may perform better (at the potential cost of speed).
- If you’re unsure, test a sample document with Engine1, Engine2, and Engine3 to compare results.
Can OCRSpace create searchable PDFs and what options exist?
Yes. OCRSpace can produce searchable PDF outputs. You can select:
- Create Searchable PDF (with a visible text layer)
- Create Searchable PDF with visible text layer
- Create Searchable PDF with invisible text layer
These options generate a PDF that includes the original image plus a text layer that allows searching and copying.
How can I use the OCR API for automated or batch processing?
For automated OCR processing and batch document conversions, OCR.space provides a free OCR API. This API is intended for programmatic use and automation, separate from the online interactive interface. If you’re processing many documents or integrating OCR into applications, use the API and consult the API documentation for details.
Is my data private and what happens to my files after processing?
Yes. All uploaded files and extracted text are automatically deleted immediately after OCR processing. OCR.space does not store, archive, or retain your data beyond the processing needed to complete the OCR task (as described in the privacy policy).
Are there pricing plans beyond the free online service?
OCR.space offers a Free plan and paid plans (such as PRO, PRO PDF, and Enterprise) with higher limits and additional features. For specifics on plans, limits, and pricing, please refer to the OCR.space pricing information.
Are there additional tools or resources available (e.g., browser extensions or integrations)?
Beyond the online OCR service and the API, OCR.space provides resources such as an OCR API, a browser extension, and open-source RPA integrations. These are available to support automation and integration workflows in addition to the online OCR experience.
