webtools
Favicon Inspector
Inspect a website’s favicons: every way a site can declare them (icon link tags, apple-touch-icon, mask-icon, web app manifest, Microsoft tiles, well-known paths) plus what Google’s and DuckDuckGo’s favicon services return. Shows how each icon was found, its real format and size, and downloads any of them as PNG.
Hello World
A friendly greeting and a demo of the webtools format.
M4B Audiobook Inspector
Inspect M4B/M4A audiobook metadata in your browser: tags, cover art, chapters and technical details, with playback and chapter jumping. Files are read locally with byte-range slicing — nothing is uploaded.
SVG Icon Tester
Paste SVG, tune sizes, preview on multiple backgrounds, export PNG.
