I'm currently doing an assignment that tells me I have to create a 300dpi A3 poster to advertise a graphic design convention, and that I have to make another version of the image for web that is no bigger than 30k. I'm having real trouble with this, I'm having to reduce the dpi to much less than 72 and take colours down to 128 to get it anywhere near the 30k. I was wondering if anyone else out there has any tips or alternate methods of getting the file size right down?

Any help is much appreciated - Dan.

How big does the online version have to be in pixels? DPI is meaningless for onscreen graphics

[DanBeckett]

I dont think it specifies a pixel size, my assumption it would have to be fairly similar to the poster but I'll have to check this. All I have to go off is that it has to be less than 30K... Can I perhaps pull the DPI right down with out too much quality loss?

Many thanks for any help

Just make sure to resize your image to a smaller, more web-safe size and if you're using Photoshop make sure to use the "Save for Web" option. Compressing it this way will get you great results with a smaller file size.

Like Faken said, DPI in screen graphics is meaningless. It doesn't affect your overall file size.

Look around for image compression software. I had a program once.
