About Math Formula OCR

Math formula OCR saves you rebuilding an equation symbol by symbol, be it a formula in a textbook photo, a screenshot from a paper or a derivation in a scanned PDF. Upload a JPG, PNG or WEBP image or a PDF, and an AI vision model reads the formula. The ordinary text in a scanned PDF can be made searchable and copyable with OCR PDF.

Pick the Output you need. LaTeX suits papers, Overleaf and Markdown notes, MathML suits web pages, and Word equation is for documents you write in Microsoft Word. Each task uses AI credits; free users get 1 AI task a day and VIP plans include a monthly allowance. Check the result against the source before you publish, especially subscripts and brackets.

FAQ

Math Formula OCR: questions and answers

What can math formula OCR output?
LaTeX, MathML or a Word equation. Choose it under Output before you start.
Does math formula OCR work on PDFs?
Yes, it accepts PDFs as well as images. For the best result, upload just the page that holds the formula; Extract PDF Pages can cut it out.
How do I get the best result?
Crop tightly around the formula, keep the image sharp and upright, and use a screenshot rather than a photo when you can.
Why does it cost an AI credit?
Formulas are read by an AI vision model, which is costlier to run. Free users can run 1 AI task a day, and each VIP plan comes with a monthly allowance.
Are my files kept?
No. The image or PDF and the result are removed from our server an hour after the task, and we never use them to train AI.
