PhotoRefiner

PhotoRefiner is a simple-to-use Windows program that enables you to make some adjustments to image files. It offers support for JPG, BMP, GIF, PNG and TIF photo formats.

Installing the app does not take a long time, nor require special attention. Its interface is clearly outdated, but it is simple to work with. Images can be opened via the file browser only, since the drag-and-drop support is not implemented.

A toolbox shows the cursor's current position in magnified form. It is possible to zoom in and out, view photo info (e.g. full path, size, resolution, color depth), resize it with or without keeping the aspect ratio, add borders of any color, crop any part of the picture, as well as rotate it to any angle.

As far as image adjustments and effects are concerned, you can tweak the levels for brightness, contrast, sharpening, smoothing, gamma, RGB and HSL, convert the photo to grayscale, invert colors, or pixelate the image. Modifications can be overwritten to the original file or saved to a new one.

The tool is very light when it comes to CPU and RAM, so it does not affect the PC's overall performance. There were no kind of issues in our tests, since it did not hang, crash or pop up error dialogs. However, PhotoRefiner has not been updated for a very long time, and this can be clearly seen from the interface and skillset.
