Enlarging images, especially from lower resolution source images, can be dicey business.

Want to enlarge an image and you don't want it to look like an 8-bit video game sprite? SmillaEnlarger can keep things smooth.

SmillaEnlarger is an open-source and portable application designed to help users intensively massage an image enlargement to keep it from looking jagged and filled with pixels.

Users can...

• select the level of zoom using the zoom slider and the location of the zoom via the selection box.
• begin tinkering with the...
  • sharpness,
  • flatness,
  • dithering,
  • noise levels, and more.

Note: The preview function is quite speedy so don't hesitate to preview often to check how the various settings effect the outcome of your image.

When the enlargement is satisfactory, hit the Calculate button to render it—a process only slightly longer than the preview.

From my testing, the results achieved with SmillaEnlarger are on par with other—much more expensive—methods.
