Seasy – Image Zoom

Zoom web images with your mouse wheel or trackpad. Enlarge screenshots, charts and photos instantly.

Seasy is an image zoom tool that helps you see small web images, screenshots, charts, and photos in greater detail. Point at an image, hold Alt (Option on Mac), and scroll your mouse wheel to zoom directly. Two-finger trackpad scrolling is also supported. When an image is near the edge of the screen, Seasy adjusts its position to keep as much of it visible as possible. For a closer look, hold the modifier key and click an image, or open the preview from the image’s context menu. You can then zoom and drag to explore details. In settings, choose Alt / Option or Shift and turn direct zoom and click-to-preview on or off independently. Seasy works automatically on ordinary web pages, so you don’t need to click the extension icon each time. Image previews are processed locally. No account is required, and images and browsing history are not uploaded.
