OCRMD: OCR for Math, Tables & Complex Docs

Scanned PDFs, phone photos of pages, and image-only files are still everywhere. The text is there, but you cannot select, search, or edit it without retyping. That is the problem OCR solves. OCRMD focuses on the cases where basic OCR falls apart: math, tables, and messy layouts.

What Is OCR?

Optical Character Recognition (OCR) turns scanned papers, image PDFs, and photos with text into editable, searchable data. If the text in your PDF is not selectable, OCR is usually faster than typing it out by hand.

Standard OCR is fine for plain paragraphs. It often breaks on formulas, tables, and anything that is not a simple block of text. That is the gap OCRMD is built for.

When Do You Need OCR?

You probably do not need OCR every day. It does matter when:

1. Working with scanned documents or images containing text - Old reports, books, or papers that exist only in physical form or as images
2. Extracting text from non-selectable PDFs - Documents that look digital but do not let you select or copy text
3. Searching through image files - Finding specific information inside scanned documents
4. Converting raster PDFs into editable ones - Turning image-based pages into text you can actually work with
5. Extracting tables and structured data - Keeping rows, columns, and relationships instead of one flat string

Math-heavy papers and technical documents are where generic OCR hurts the most.

When You Don't Need OCR

We would rather be upfront about when OCRMD is not the right tool:

• If your PDF already has selectable text and you do not need to copy math from it, OCRMD is probably more than you need
• Born-digital, vector PDFs are often fine with simpler tools
• If you only need plain text from a simple image, try our free client-side image OCR first

We built OCRMD for math, complex formatting, and structured data. If that is not your problem, another tool may be enough.

The OCRMD Difference: Not Just Text, But Meaning

Jonas Fröller started OCRMD because most OCR tools either skip math and tables or turn them into garbage. OCRMD treats them as first-class content.

Specialized Mathematical Recognition

OCRMD detects equations and outputs LaTeX, not a bitmap or a string of random symbols.

For example, when OCRMD encounters the quadratic formula:

$x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$

You get LaTeX you can edit and drop into papers, slides, or notes.

Preserving Table Structure

Flat OCR often destroys tables. OCRMD outputs Markdown tables with rows and columns intact, which helps if you need to move data into a spreadsheet or analysis tool.

Output That Respects Format

Instead of a single plain-text dump, OCRMD gives you Markdown with LaTeX blocks for math. Less cleanup before you publish or archive the result.

How OCRMD Works

1. Upload your document - PNG, JPG, WEBP, and PDF
2. Processing - Text, tables, math, and images are detected
3. Preview and download - Edit the Markdown, then download or export as a vectorized PDF

On the free tier, image OCR runs in your browser, so the file does not leave your machine. Premium handles PDFs on our servers with models that reach 90-99% accuracy depending on scan quality.

Who Benefits Most from OCRMD?

• Researchers & Academics - Papers and books with heavy notation
• Scientists & Engineers - Technical docs and formula diagrams
• Students - Searchable notes from textbooks or lecture slides
• Developers & Data Scientists - Parsing technical PDFs in a pipeline

Free vs. Premium: Finding the Right Fit

Feature	Free Version	Premium Service
Document Types	Image files only (JPG, PNG, WEBP)	PDFs and image files
Processing Location	Client-side in your browser	Secure server processing
Math & Table Extraction	Basic support (No)	Advanced recognition & formatting
Accuracy	Good	90-99% depending on input quality
Account Required	No	Yes
Document Storage	No	Yes, with organization features
Full-Text Search	No	Yes, across your document library
Free Trial	Always Free	3 free extractions Included

Free is enough for occasional image OCR. Premium is for PDFs, math, tables, and a document library.

The Future of OCRMD

Planned work includes batch uploads, customizable Markdown rendering, search across your library, more image formats, translation, and chat over imported documents.

Why Choose OCRMD?

• LaTeX output for math
• Tables kept as structured Markdown
• Layout and hierarchy preserved where the source allows
• Usable on noisy scans
• Markdown you can publish or pipe into other tools
• Optional raster-to-vector PDF export
• Client-side image OCR when you want local processing

Built-in PDF "OCR" in some readers works until you hit real notation. OCRMD handles math as math from the start.

Extract Meaning, Not Just Text

If your files are stuck as scans or non-selectable PDFs, especially with formulas or tables, you do not have to retype them. OCRMD is built to return text plus structure.

Researchers, students, and anyone sitting on data-heavy reports can get editable Markdown instead of a dead image.
