Guide: Export Formulas and Convert Images to Typst

Write, preview, export

Take your formula from the editor to a document, slide, or website.

Write your formula
Type in the editor or use the symbol toolbar. In Simplified Formula Mode, leave out the surrounding $ signs.
Check the preview
Review the rendered formula and fix any syntax errors before exporting.
Choose an export
Use Export Image for PNG, SVG, or JPG. Use Export Code for Typst, HTML, or MathML, then download or copy the result.

Choose the right format

PNG: For notes and slides. Supports transparency; increase export scale in Settings for more pixels.
SVG: Stays sharp at any size. Check that your destination supports SVG; SVG from the Typlet renderer embeds its font, which some editors and office apps cannot show.
JPG: A raster image with a white background.
HTML: An image embedded in an HTML snippet or a complete page.
MathML: Formula markup for web pages and tools that read MathML. The Typlet renderer can also copy its own HTML, which needs the Typlet stylesheet it links to.
.typ: Editable Typst source for later changes or a backup.

Copying PNG requires browser support and HTTPS on a public site.

Try a formula example

sum_(i=1)^n i = (n (n + 1)) / 2

This sums the first n integers. Use / for a fraction and _ and ^ for the lower and upper limits.

Open example in editor

If the preview or export looks different

TypstPad renders with Typlet by default. For a document Typlet cannot render, custom fonts, or packages, choose typst.ts (Legacy) above the preview. Check the formula mode too. For a sharper PNG or JPG, increase export scale in Settings. Shared links keep the formula mode but not the renderer, custom fonts, or other editor settings.

Turn a screenshot into Typst

Recognize one printed equation. Your image stays in your browser.

Crop one formula
Keep the complete equation in a clear PNG, JPEG, or WebP image under 20 MB.
Run recognition
Open Image to Typst in the editor. Select, drop, or paste the image, then choose Recognize formula.
Review and use
Compare every symbol with the image and edit the draft. Use in editor replaces your current formula; check its preview before exporting.

Tips for better results

Use a sharp crop with all accents and indices visible. Light, dark, and transparent backgrounds are supported. Avoid blurred photos, shadows, handwriting, and full pages.

Model download and privacy

First use downloads TypLens V1.1 INT8 (33.1 MB of weights) and its runtime. Recognition runs locally, without uploading your image. The model is experimental.

If recognition is wrong or incomplete

Try a clearer crop or enter the difficult part manually. Incomplete output and invalid tokens cannot be inserted. A formula can compile correctly and still contain the wrong symbols.

Save and share your work

Keep a local collection, send a link, or download a copy.

Save in this browser
Choose Save to add the formula to your collection. Use Load to open it again.
Share a formula
Choose Share to copy a link. Anyone with the link can read the formula source.
Keep a backup
Use Export Code to download a .typ file. It keeps the source editable outside this browser.

Where are my formulas stored?

Drafts and saved formulas stay in this browser and do not sync across devices. Clearing site data removes them. Download a .typ backup for anything you want to keep.

What does a shared link include?

A link contains the current formula source and its formula mode. It does not include your collection, custom fonts, or other editor settings. Opening a link replaces the editor content and keeps your previous draft in your collection. Check the preview when opening it in another browser.
