Tools

Resize and compress large images for the web

Resize and compress large JPEG, PNG, WebP, or AVIF sources (up to 50 MB) in your browser — nothing is uploaded. Export WebP, PNG, or JPEG, plus AVIF when your browser can encode it. Same engine as the CLI and MCP.

1200×630 social preview images

Generate Open Graph and Twitter Card preview images from gradient or split templates. Set title, subtitle, brand name, and optional logo — download PNG plus copy-ready meta tags via `image og`.

Complete favicon packages from one source

Generate favicon.ico, Apple Touch Icon, Android Chrome PNGs, and SVG from a single PNG, JPEG, WebP, or SVG source — same `image favicon` action on Web, CLI, and MCP. Download assets as a ZIP.

Format, validate, minify, and analyze JSON

Pretty-print, validate with line-level errors, minify, sort keys, and compute structural stats — all via the shared `json` registry on Web, CLI, and MCP.

Convert HTML documents to Markdown

Convert headings, links, lists, code blocks, and tables from HTML into clean Markdown using `html markdown` — paste, upload, copy, or download on Web; file paths on CLI and MCP.

Safe SVG compression with accessibility preserved

Optimize SVG with SVGO while preserving viewBox and accessibility metadata — paste or upload on Web; file paths on CLI and MCP (`image svg-optimize`).

Capture PNG screenshots of any URL

Headless Playwright screenshots with configurable viewport, full-page capture, lite mode, and wait-until options — `web screenshot` on Web, CLI, and MCP. Production uses Sparticuz Chromium on Vercel.

Inspect and validate page metadata

Parse HTML or fetch a public URL for title, description, Open Graph, Twitter Cards, JSON-LD, robots, and canonical tags. Returns validation issues and suggested missing tags via `web inspect`.

URL-friendly slugs from any text

Convert titles and labels into clean URL slugs with accent stripping, Unicode normalization, and a configurable separator — `slugify run` on Web, CLI, and MCP.

Convert text between naming conventions

Convert identifiers between camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE, and Title Case via `string case` on Web, CLI, and MCP.

Environment diagnostics for deploys

Run server-side environment checks — Node.js version, Sharp availability, and related runtime diagnostics via `doctor check`. Useful on deployed instances to confirm image tools can run.
