Compress Your PNG Files from the Right-click Menu
Most of the images I use on this website are PNGs (Portable Network Graphics.) The reason I use them is because they are lossless and look great when they are transparent. Most modern browsers support transparent PNGs and they can help make a website look great. However, when you create a PNG in MS Paint, Photoshop, etc. you may find they’re a lot larger in size than JPG of GIF files. In this guide you’ll learn how to compress the files from the right-click context menu in Vista.

(Get pngcrush-*.*.*-win32.zip)

1. Download and install PNG crush

2. Extract pngcrush.exe to C:\Program Files\PNG Crush (if you choose another location, you will need to modify the registry key)

4. Now right click on any PNG file and select PNGcrush. You can compress many files at once if you like. All compressed files will be put in a folder named Crushed within the directory that your PNG files are in.

This is great! A question: does it also remove the PNG chunks? Like in the command line:

pngcrush -rem cHRM -rem gAMA -rem iCCP -rem sRGB infile.png outfile.png

Thanks!

Yes, it removes unwanted ancillary chunks.

Tried pngcrush on a few files (from 50kb to just over 300kb). Found that Fireworks naturally compresses png’s to within 5kb of pngcrush. I only tested 3 or 4 files though… still a cool program… your reg hack makes things simple as well

Okay, quick update… ran crush on one more file- just for fun- it took this fireworks png from 66kb to 42.???
Ran it again on another similar file, same thing: about 25% reduction… but still almost nothing on my 300kb header image that I was really hoping to shave some weight off of. Oh well, cool tool.

Is there any way that the right-click option appears only when right-clicking on a png file?
