Convert images to HDR, EXR, TIFF and more with Imagenator

Imagenator is a portable, open-source tool for converting digital images between various formats: BMP, EXR, GIF, HDR, ICO, J2K, JP2, JPG, PBM/ PGM/ PPM (both RAW and ASCII), PFN, PNG, TGA, TIF, WAP, XPM.

The program supports a range of format-specific options. Export to ICO, say, and you can select an icon resolution from 16×16 to 256×256; JPEGs have Quality and Subsampling options; EXRs give you control over image compression (you can choose lossy, lossless, or none at all), and more.

You’re also able to set the maximum size (width or height) of an image. Anything larger will be resized with your choice of algorithm (box, bicubic, bilinear, bspline, Catmull-Rom, Lanczos3).

An Output Pattern option helps to define custom output folders and file names. Something like {M}-{d}\{fn}-{n} , for example, will generate a subfolder based on the current month and day, before using the original file name, and adding a number from this batch (Feb-4\Filename2.jpg, for example).

When you’ve finished, clicking Start quickly processes your source files, saving the results according to your specified rules.

Imagenator doesn’t have the longest of features lists, then, but its support for some relatively unusual file formats, as well as the fine control you get over format options and resizing algorithms, means it could be useful for some people. If that sounds like you, go take a look.
