Screenshoter

Screenshoter is a browser‑based utility that lets you capture screenshots of your desktop, application windows, or browser tabs without installing any software. After capturing, you can instantly annotate the image with text, shapes, pencils, highlighters, and cropping tools. Upload existing images to edit, save results as PNG, JPEG, or PDF, or share a direct link. The service is free, requires no account, and works across major operating systems.
