How do I convert an image to ASCII art?

Upload any image (PNG, JPG, GIF, WebP) by clicking the upload button or dragging and dropping. Adjust resolution and character set, then copy or download the result.

Is this tool free to use?

Yes. Browser conversion is free with no sign-up required, and trusted PlatPhorm or Vercel Blob image artifact conversion is public. Untrusted external image URLs and protected write actions require PLATPHORM_API_KEY.

Does this tool support MCP (Model Context Protocol)?

Yes. The tool exposes an MCP endpoint at /api/mcp with tools for inline image conversion, trusted artifact URL conversion, BrowserOps screenshot conversion, artifact manifests, health checks, charset listing, and webhook management. Discovery at /.well-known/mcp.json.

Can BrowserOps or AgentUI publish screenshot artifacts to ASCII without a key?

Yes. Trusted *.platphormnews.com and Vercel Blob image artifact URLs can be converted without PLATPHORM_API_KEY. External or untrusted image URLs require PLATPHORM_API_KEY and SSRF, type, and size guardrails.

Open Source Documentation

PlatPhorm ASCII is a browser-first image-to-ASCII converter with public discovery files, OpenAPI, MCP JSON-RPC, LLMS.txt, feeds, sitemap, trusted artifact intake, and deASCII-compatible color sidecars. Contributions should preserve the simple converter UI and improve tested product behavior.

Contribution Contract

Do not degrade ASCII output quality, line breaks, copy/download behavior, or deASCII handoff.
Keep plain text compact; color travels through exact source color grids and compact chroma metadata.
Use PLATPHORM_API_KEY only for protected mutation, ingestion, publishing, and external untrusted actions.
Update OpenAPI, LLMS, sitemap, feeds, trust, and tests when public behavior changes.
Prefer standards-based HTML, structured data, semantic navigation, accessible labels, and browser-compatible APIs.

Verification Commands

pnpm testpnpm typecheckpnpm buildRUN_LIVE_INTEGRATION_TESTS=true pnpm test:livepnpm test:e2e

Live integration tests are read-only unless PLATPHORM_API_KEY is present. Browser tests should verify the primary converter surface rather than internal implementation details.
