About OCR Math Extractor
Mathematical equations are some of the hardest things to digitize, retyping symbols, fractions, and exponents by hand is painful and error-prone. The OCR Math Extractor reads the equations on your scanned pages and converts them into a digital form you can reuse, so you do not have to rebuild every formula from scratch.
Upload your scanned PDF and the tool recognizes the mathematical notation and returns the extracted equations. It is free, runs in your browser, needs no account, and your file is processed only for the recognition and not stored. Math notation is intricate, so clear, high-quality scans give the best results, and it is always worth checking complex expressions against the original before you depend on them.

FAQ
What kind of math can it read?
It recognizes mathematical notation like equations, fractions, and symbols, working best with clearly printed expressions.
How accurate is it for complex formulas?
Simple expressions read well, but intricate or multi-line equations can be harder. Always verify complex math against the source.
Does scan quality matter?
A lot. Sharp, high-resolution scans give far better recognition than faint or blurry ones, especially for small symbols.
Can I use OCR Math Extractor on mobile?
Yes — ToolHub is fully responsive and works on iPhone, Android, tablets and all modern browsers. No app install needed.
