Frequently asked questions

Do I need to install anything?

No. Everything runs in your browser. Paste a public URL and we capture the page for you, or upload a screenshot you already have.

Is there a watermark on the export?

No watermark, no signup, and no limit on exports. The PNG you download contains only your screenshot and your annotations.

Can I annotate a page behind a login?

URL capture only reaches public pages. For anything behind a login, take the screenshot yourself and upload the image — annotation works exactly the same.

What annotation types are supported?

Numbered callout pins that auto-increment, arrows drawn in any direction, rectangle highlight boxes, and text labels. Each element can be deleted individually or cleared all at once.

What resolution is the export?

The PNG exports at the captured image's native resolution, so a full-page capture stays sharp when you drop it into docs, a deck, or a support article.
