Photo of Math to LaTeX
Photo of math to LaTeX: you've got a textbook page or a paper with formulas you can't copy out of. Upload it and every displayed formula comes back as native LaTeX, editable against a live preview, exportable as a compile-ready .tex file — headings, text and tabulars included.
How it works
- 1
Upload the page — a photo, scan or PDF of printed math.
- 2
Each displayed formula is detected as its own block and recognized as native LaTeX.
- 3
Edit against the live preview if anything looks off, then export .tex, Markdown or HTML.
Why OhMyOCR
Native LaTeX out
Displayed equations come back as LaTeX source, not as pictures of math you would have to retype.
Live rendered preview
Edit a formula and the rendered version updates as you type. A wrong subscript gets caught before it reaches your document.
Compile-ready .tex export
One click builds an article-class .tex — sections, escaped text, tabular tables and \[…\] display math — ready to compile.
Whole-document context
Formulas come back alongside the surrounding text and tables, each linked to its exact spot on the page.
Why math is the hardest OCR — and why LaTeX is the right output
Ordinary OCR reads left to right. Mathematics does not work that way: superscripts, subscripts, fractions, radicals, integral limits and matrices put meaning in vertical position and size. Flatten x² into x2 and the statement is simply wrong. Math OCR has to recover that structure, not just the symbols.
That is why the output format decides whether the result is usable. LaTeX preserves structure losslessly and compiles anywhere — papers, theses, Overleaf, Jupyter, Anki cards, MathJax and KaTeX on the web. OhMyOCR returns displayed formulas as native LaTeX source instead of pictures of equations.
Trust, but verify — with a live preview
One wrong subscript changes what a formula means, and raw LaTeX is hard to proofread by eye. The workspace pairs every recognized formula with a live rendered preview: compare it against the source region, and when something is off, edit the LaTeX and watch the render update as you type.
Whole documents work the same way. A scanned problem set, lecture notes, a paper chapter — formulas are recognized alongside the surrounding text and tables, and the one-click .tex export builds a compile-ready article: sections, escaped text, tabulars and display math in place.
Frequently asked questions
How do I convert an image of an equation to LaTeX?
Upload the page to OhMyOCR, open the Formulas tab, and each displayed equation appears as LaTeX with a rendered preview. Copy the source you need or export the whole document as .tex.
Can I edit the recognized LaTeX?
Yes. Double-click a formula block and its source opens with a live KaTeX preview underneath — the rendered result updates as you type.
Does it export a full .tex document?
Yes. The export builds an article-class document: headings become sections, tables become tabulars, and display formulas are placed in math environments.
Does it work on handwritten math?
Printed formulas are the primary target. Handwritten regions get flagged for review, and results track legibility — the inline editor with live preview keeps fixes quick.
