What is Unlimited OCR?
Unlimited OCR is a free AI-powered tool that converts photos, screenshots, scans, and multi-page PDFs into clean, structured Markdown text. It runs entirely in your browser — no registration, no account, no setup. You simply drop in an image or PDF, and the cloud-based document AI returns editable, searchable text that preserves the original layout logic: tables stay as rows and columns, headings stay headings, and formulas come out as LaTeX.
The tool handles JPG and PNG files up to 10MB, and PDFs up to 50MB with as many as 100 pages per run. Batch upload is supported, so you can drag in several files at once and each processes independently. Output formats include Markdown, plain TXT, and spreadsheet-ready rows, making the results immediately usable in notes, knowledge bases, or further editing workflows.
Who it's for
- Students and researchers — turn scanned papers and lecture slides into Markdown notes, with equations preserved as LaTeX for Overleaf, Obsidian, or Notion.
- Finance and operations teams — convert receipts and invoices into structured rows with vendor, date, totals, and line items ready for spreadsheet import.
- Developers and AI builders — feed clean structured Markdown directly into RAG pipelines or agent workflows, with headings and tables intact.
Key features
Image to text
Convert screenshots, scans, photos, whiteboards, and receipts — JPG or PNG — into editable, selectable text. The engine handles handwriting, stamps, low-contrast scans, and dense tables where older OCR tools typically fail.
Long-document PDF OCR
Scanned contracts, reports, and book chapters become searchable Markdown with reading order preserved across columns and pages. Up to 100 pages per run, with no text layer required to start.
Free and unlimited
No account, no card, no daily cap. The free version is the complete product — run as many documents through it as you need, with no signup walls or hidden limits.
Batch upload
Drag in several files at once. Each is submitted as its own job and returns its own result, so one slow document never holds up the rest of the queue.
What stands out
"The free version is the complete product — no caps, no walls, just clean Markdown."
Most OCR tools rely on outdated browser engines that break tables, fail on handwriting, and stall on large files. Unlimited OCR uses cloud document AI, so the same scan comes back clean — headings and tables intact, mixed Chinese and English detected automatically, and formulas preserved as LaTeX. Files are encrypted in transit and nothing is stored after processing, which matters for sensitive contracts, statements, and IDs.
Worth checking out if…
You're tired of OCR tools that flatten tables into broken text, cap you at a few pages, or demand an account before you can try them. If you need to digitize scanned literature, organize lecture notes, process receipts in bulk, or make scanned PDFs searchable with Ctrl+F, Unlimited OCR delivers structured output without friction. It's especially useful if you work with mixed-language documents or need spreadsheet-ready rows from invoices — all without paying or registering.
