I have a logo in .tif format, compressed in LZW compression. My ERP provider says that, in order for my logo to be compatible with their software, it must be in .tif format with no compression.

Does anyone know of a tool for decompressing .tif images with LZW compression?

I'm kind of desparate here.

Eh. LZW is a pain.
What program are you trying to open the file in? Are you on a Mac or a PC? What OS? Also, was the file compressed on a Mac or a PC?

Can you open it normally in Photoshop or another program? If you can, then you should be able to save it as and set compression to nothing, or save it as a .png or .psd and then resave as .tif.

I'm opening it in IrfanView on a PC. I'm not sure what type of device originally compressed it.

Once you have the image open, go to Save As, and with TIF selected in the Save as type: box, Tiff save options will show Save Compression. Choose None and save the file, re-naming it if you wish to retain the compressed original as well.
