Small tools that do one job well: capture a full-page screenshot of any site, check whether an email address is deliverable, and pull a site's favicons in every size.
Take high-quality screenshots of any website in various resolutions.
Validate email addresses — check format, MX records, disposable/free provider detection, and deliverability score.
Extract all favicon images from any website — icons, apple-touch icons, OG images in all sizes and formats.
Three unrelated tools that each answer one question completely. Screenshot Capture gives you the page as a first-time visitor sees it, without your extensions or logged-in state. Email Validator checks format, MX records and whether the domain is a known disposable provider — worth running before adding an address anywhere. Favicon Extractor pulls every icon size a site publishes, which is the quickest way to grab a brand mark at the right resolution.
