How SVG to Markdown works

  1. SVG
  2. image detection
  3. SVG text · your vision callback
  4. GitHub-Flavored Markdown

Built for JavaScript runtimes

Node.js

Read local files, uploads, S3/R2 objects, and other byte sources.

Cloudflare Workers

Detect images inside Workers. SVG converts locally. Raster images use the callback you register.

Browser

Convert SVG locally. Raster images need a vision callback in your application.

Edge

Run the same TypeScript converter in compatible Edge runtimes.

What @mdgate/image extracts

  • SVG / SVGZ titles and visible text
  • JPEG, PNG, WebP, GIF, TIFF, HEIC, and BMP via your callback

SVG vs Raster image

SVG

SVG text → @mdgate/image → Markdown

Raster image

JPEG / PNG / … → your vision pipeline

@mdgate/image does not silently send images to an OCR or AI service.

Why @mdgate/image

Runs where your JavaScript runs

No separate processing service. The converter is TypeScript you can call from Node.js, Cloudflare Workers, Edge runtimes, and browsers.

Local conversion

SVG files can stay inside your application or browser.

Content detection

Recognizes SVG files from their contents, not only the filename.

Deterministic parsing

The same SVG file produces repeatable Markdown without model inference.

Small runtime surface

No Python. No native addons. No WASM. No third-party runtime dependencies.

SVG for AI agents

Turn SVG files into content your agent can actually work with.
