InkVec Formula Studio — browser-based LaTeX to image

Turn LaTeX formulas into paste-ready transparent images in one step for papers and slides

Problem

A V2EX user complained that putting LaTeX formulas into PPT, blog covers, or editors that don't support LaTeX means opening an online editor, typing the formula, taking a screenshot, cropping it, and redoing everything if the background or sharpness is wrong. Doing this many times a day is painfully repetitive.

Solution

A pure browser tool that renders LaTeX live and exports PNG / SVG / JPG with transparent backgrounds, multiple resolutions, batch queue, and preset themes—all processed locally with no upload of formula content. Package it as a PWA or browser extension so copying a formula image becomes a single action.

Users

Graduate students, university instructors, technical writers, and engineers who frequently make academic or technical presentations

MVP

Live LaTeX rendering; PNG / SVG / JPG export; transparent background and 1x–4x resolution; formula history and favorites; fully local, no backend

Revenue

Free basic tier plus paid bulk export, private themes, and custom fonts; alternatively a one-time purchase desktop add-on or browser extension

Why now

MathJax and KaTeX are mature, and browser-side Canvas / SVG export is capable enough to build a lightweight frontend-only tool with almost no backend cost—ideal for an indie developer to ship quickly
