OCR.space Pricing 2026

Free OCR API with rate limits — and a markdown-output alternative if you need structured documents instead of plain text.

TL;DR

  • OCR.space has the most generous free OCR API tier: 25,000 calls/month at $0. File size capped at 1 MB and PDFs at 3 pages on free.
  • PRO is $30/month for higher limits and SLAs; PRO PDF ($60/month) lifts file size to 100 MB+ and PDFs to 999+ pages.
  • Output is plain text only. No markdown, no tables, no math. LensCopy is the upgrade if your downstream needs structured output.
