Free website tools

Tools we built, free for you.

Small utilities we use every day. They run in your browser, except the share preview, which fetches the page you enter. No sign-ups.

ROI Calculator

See when a new website or custom software pays for itself.

Tag a link so analytics shows which ad, email or post sent each visitor.

Resize, crop and compress images in your browser. Drop in a batch, pick a preset, download the results.

Fill in a form and get JSON-LD structured data you can paste into your page, with hints for missing or malformed fields.

See roughly how a page may appear in Google, and whether the title and description fit before they get cut off.

Enter a page address to see how its link may look when shared, and which share tags are missing or wrong.
