Thanks Mr. Lemke,

I use it on my old Powerbook G3 while I'm on the road.

If you work on X the whole day, OS 9 is very nice to use from time to time.

Thank you for supporting GraphicConverter Classic in these X-days.

My one complaint about GraphicConverter is file size. I always have to convert the JPEG's and GIF's with another application to shed off the file bloat GC seems to always throw into the files. Otherwise, it's a great application, the perfect companion to Photoshop.

I use GraphicConverter every day, converting files from one format to another. I've never noticed any bloat such as you mention, on the contrary, after conversion in GraphicConverter, the files are smaller. I'm thinking you had best check your preferences settings carefully.

In preferences, under Save, check to make sure you've turned off the option which inserts a thumbnail in the picture. This can (and does) double the size of the picture. I like the thumbnails because they help with organising my pictures, but if you're looking to save some disk space, I can see where they'd be annoying.


I know what you mean about the file size. Even with all the extra stuff turned off, they are bigger than they need to be. I usually open them up in ResEdit afterwards and deleting ALL the resources that appear and they become smaller and still open up fine.

note: text insertion into a jpeg graphic file seems to be broken in my copy of 5.3... I've gone back to 523 for the time being.

This app, which I've used for almost 10 years now, should really be called Graphic Master, it is so useful and full-featured. Unless you need to create vector graphics a la Adobe Illustrator or work with multiple layers simultaneously a la Photoshop, there is virtually nothing this app won't do. I use it every day, as both my main (actually, sole) image viewer, browser and converter, and as my graphics editor for any and all purposes except those I MUST reluctantly turn to a bloated monster like Illustrator or P'shop for.

GKON's a thumbnailer, a pixel editor, a photo retoucher, a graphics library manager, a formatter, a slideshower, a crop-n-scaler, a paint program, you freakin' name it.

My absolute FAVORITE thing about GKON, though, is that it somehow produces the smallest JPEGs at any given image quality/compression level out of every app I've ever tried over the last 15 years. I don't know what Lemke's doing to optimize this so much, but it sure works!

My only ideas for future improvement at this point would be:
1) Someone desperately needs to reverse-engineer AOL's darned .ART format and make a GKON plug-in for it.
2) GKON would be even more THE bad-@ss graphics app of the Mac world if it supported Photoshop-format plugins. I get frustrated that I have to fire up gargantuan old P'shop or another compatible app to use the 100s of plugins I have, and I'd kill to be able to use them in the only graphics app I actually enjoy using.
3) Images look a little distorted (i.e. slight jaggies on curves) when you have GKON display them at the max size that will fit on screen and that size happens to be between about 85 and 95% real image size. I'd like to see the display routines adjust a little better in this circumstance.
4) Support for creating ASCII art from any selected image. Just kidding!
