Product Information
What is Unlimited OCR?
Unlimited OCR is a web app for extracting editable text from photos, screenshots, scans, and multi-page PDFs. You drop in JPG or PNG files (up to 10MB) or PDFs (up to 50MB and 100 pages), and the cloud engine returns Markdown or plain text with headings, lists, tables, and LaTeX formulas preserved. Batch upload runs each file as its own job so one slow document does not block the rest. Language detection is automatic, including mixed Chinese and English on the same page. There is no account, no daily cap, and files are not stored after processing.
How to use Unlimited OCR?
- 1. Open unlimited-ocr.com in your browser — no account is required
- 2. Drag in one or more JPG, PNG, or PDF files, or paste a screenshot
- 3. Complete the quick check if asked, then wait while each file is parsed in the cloud
- 4. Preview the result and copy or download it as Markdown or TXT; tables stay as rows you can paste into a spreadsheet
- 5. For a batch, download each result separately or as one merged file
