Paste any URL and get a real accessibility audit: every failing element outlined, every WCAG criterion graded by conformance level, powered by axe-core in a full Chrome render. No signup, no email wall, no "you're compliant" badge — it tells you exactly what's broken and what still needs a human. Free scanner, Chrome extension, npm CLI / GitHub Action for CI, and an MCP server for AI coding agents.
ImageDimensions is a suite of free image utilities. Scan any URL to find oversized images (natural vs rendered dimensions, per-image breakdown), or convert PNG and JPG to WebP entirely in your browser — files never leave your device, since conversion runs locally via WebAssembly. No signup, batch support, adjustable quality, no watermarks.
