Actually it's not ideal to send AI (Adobe Illustrator) files to business contacts since most people cannot open them. I would advise to export to GIF instead (more suited for graphics, JPEG being optimized for pictures). With GIF format, just check your colours after conversion in case some have been substituted!

If you really need to send your file in AI format, here is a little trick: open your file with AI, select All, copy and paste it into a new image, save that new image. I don't know why but usually that new file is much smaller than the original one.

Another thing to consider is sending the file through an FTP service that allows you to send HUGE files for free like Send This File. I use that a lot to get files to our printer.

My AI file is 8Mb but the two images are only 400K.  The remainder of the file is text.  Why is the file so big?

If you want your .ai file small then check your appearances on individual objects. If objects have drop shadows, transparency, etc. then they create a larger file size. If you are done editing the appearance then you can select the object, go to object, rasterize. This makes the object an "image" instead of an object with appearance effects and saves on file size.

When sending art to a screen print shop, the file is needed in vector format for easiest seperation of colors. All colors used shoould be named in the color palette. Screenprinters cannot use a jpg unless it is 300 dpi and even then some wont even bother trying to manually seperate the image. If it is a one color, all the art should be in black. It doesn't matter what color you print, that's determined by what color ink is put in the screen. If it is all black it makes a much better stencil to work with once printed out on vellum. Most printers only accept vector formats, or they charge an art fee. I've run into similar issues, and I've seen other vector art where once all was done it was somehow flattened to where the only points or lines left were those you can see. That's what I'm trying to find out how to do.

Hi Tom, Can I just say thanks so much for your response it really helped me downsize a massive catalogue file I had as well. Can i just add that even on the max setting the jpeg was not high enough quality for me but I got around this by scaling the file up to twice the size, exporting, and then shrinking it back down. File went from 21MB to 1.6MB!

Thanks, Holly

How to Reduce AI Vector file size: An Adobe illustrator Tutorial

My AI file size was not going under 1 MB even by deleting extras so what I did is I opened a raster small image of 100 kb with Adobe Illustrator. then deleted the image and saved the file as AI. Then I Copied the whole vector content of original AI file that was bigger then 1 MB with ctrl+c command and pasted it in the new file created with raster image. and saved it. Wow the new file size is only 137 kb now.
