JPEG Imager – это интерактивная
программа для сжатия изображений. Программа предоставляет
предварительный просмотр сжатого изображения в реальном времени и вы
можете сравнивать это изображение с оригиналом. Вы можете изменять

What's New in This Release:
Added customizable menu with preset image sizes in the Resize tool.
Added new zoom levels with a factor of 1.41 (square root of 2).
Added the option of auto zoom. When you load an image it is
automatically scaled to fit the window size. You can choose to fit the
width, height, or both.
You can bind the selected auto-fitting zoom mode to middle button click (mouse wheel click).
Now the default setting for new installations is to use bicubic
interpolation when displaying scaled-down images (zoom out). In order to
improve display speed of the viewer some functions have been rewritten
using the SSE2 instruction set.
The Text tool now lets you drag the text with your mouse.
Fixed rare AV bug when rendering text outside image borders.
A number of small changes in the Full Screen view to make it more
consistent with windowed mode (shortcut keys, synchronized zoom and
scroll position).
A brand new Crop tool:
allows you to adjust the edges of an area to be cropped by dragging them with the mouse;
darkens the area outside of the selection, so you can see how cropping will affect the composition of the picture;
you can optionally constrain the aspect ratio of the selected area (16:9, 4:3, 5:7 etc).
