BLP2PNG 
BLP2PNG does not have a graphical user interface. You can drag-and-drop files or folders onto it and it will convert them, or you can use it from command-line environments such as development tools (as I do). If you're looking for a tool with a file picker and buttons, this isn't it.
Description
This tool is used for converting bi-directionally between BLP and PNG images. The tool fully supports alpha channels and can be used as a drag-and-drop converter or from the command line. It can also convert your existing TGA files to PNG.
BLP2PNG will convert the file based on the original type:
* BLP are converted to PNG
* BMP are converted to PNG
* TGA are converted to PNG
* PNG are converted to BLP
If you drop a folder onto it, it will recursively convert every BLP image in the folder to a PNG. This is very handy for mass-converting the Blizzard artwork folder after a new patch.
Version 1.2 changes:
- Added ability to drag-and-drop entire folders for conversion from BLP to PNG
- Added 'squish' library for compressing texture for much better results when generating BLPs
- Added ability to drag-and-drop entire folders for conversion from BLP to PNG
- Added 'squish' library for compressing texture for much better results when generating BLPs

I have a small problem when I convert TGA's to PNG's for converting to BLP's. For some odd reason, d+ding TGA's makes the image flip vertically when converting to PNG's. PNG to BLP works without a hitch.
Now that I know that this happens, I can flip the TGA's around accordingly before conversion, but I was just wondering if this is normal behavior.

I LOVE you. This program is perfect. I was tearing my hair out trying to convert a blp to a viewable format before I found this. Thank you so much!

Not sure why you're getting black instead of transparancy. I use this to create my BLPs for Outfitter and Group Calendar, both of which have lots of transparancies so I know it works for me. Check the format on your PNGs, maybe there's something about them that's different than what I use. For example, grayscale PNGs with transparancy may not work. I don't know that they don't work, but I never create grayscale textures so that might be broken /shrug |

If I get around to it, I'll try converting this applet to use my newer framework which should make it easy to limit the source code to a small readable set of files. Again though, the heart of it is just libpng and libsquish. Check out libsquish btw, it's pretty nice. I originally tried developing my own algorithms for the BLP compression but they were pretty mediocre. libsquish does a really nice job though. |

Drag-and-drop: image1.tga to image1.png = convert.
image2.tga to image2.png = not convert. Why?

Any chance we could get the source code for this? I'd like to see how it works.

Version 1.2 changes:
- Added ability to drag-and-drop entire folders for conversion from BLP to PNG - Added 'squish' library for compressing texture for much better results when generating BLPs Note that the folder drag-and-drop only converts from BLP to PNG -- it will not perform any other types of conversions (BLP->PNG, TGA->PNG, etc.). I had to restrict it because otherwise it wasn't useful for extracting the Blizzard artwork folder. If it converted anything it found then it could end up converting the PNGs back to BLPs, which would modify the original BLP files. This version also uses the excellent libsquish for the texture compression, which produces vastly superior results than my own compression routines. Several of the textures in Outfitter and Group Calendar look better with this new library. |

Bugs & Feature Ideas
Personally, what I would really love is to be able to just drag my Interface folder onto the icon and have it go through all the files and convert the BLPs into PNGs so that I can use Windows Picture and Fax Viewer to actually see them. But there's a few problems:
1- It doesn't iterate through directories like that. So, it'd be great if you could add support for dropping a directory onto the program. And when someone does that, recursively iterate through the directory structure to find all the files and convert them into BLPs. 2- Another problem is that it seems to only allow you to drag 20 files at a time onto it. Every time I try 21 (or more), it gives the following error: "Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item." 3- Yet another problem, when it encounters a non-BLP file, it seems to just stop (there's no error thrown or anything). Check the file header (or even the extension) and if it doesn't appear to be a BLP file then skip it and continue with the next. So there's my feedback. I was looking for an hour or two for a tool that could actually read WoW's BLP files and yours was the only one I could find. And while I was a little hesitant about the PNG format (I generally prefer TGAs), it is quite nice being able to use the Windows Picture and Fax Viewer (which can't read TGA) instead of Photoshop to look at them. I'd definitely love to see the 2nd and 3rd things up there fixed because the tool is rather irritating at the moment. And if you could implement the 1st thing, that'd be just perfect. |

Some images are converted mirrored on X axis from TGA 24 bits to PNG. I save them with PAINT.NET.
