In their own words
OCR.space
OCR.space converts images and PDF documents into editable text through an online OCR service and API, and can create searchable PDFs. The web service accepts JPG, PNG, GIF, and PDF files without registration; its free web uploads are limited to 5 MB per document. The API returns extracted text in JSON and supports images and multi-page PDFs. It offers three OCR engines: Engine 2 is the default, while Engine 3 supports handwriting, tables, and more than 200 languages. An `isTable` option is recommended for receipts, invoices, and other table-structured documents. The free plan is free, with 25,000 monthly requests and a searchable-PDF watermark; Engine 3 has an additional 2,500 conversions, but cannot produce searchable PDFs. PRO costs $30 a month, PRO PDF costs $60 a month, and Enterprise starts at $999 a month. OCR.space Local runs offline in self-hosted environments; its license price is available from sales.
