how to keep 300dpi resolution when saving a jpeg from illustrator

[yves]

I have an illustrator cs4 file set up in 300 dpi. when I save it into a jpeg, it automatically downsizes it to 72 dpi and the quality of the image is really bad. how do i keep a 300 dpi resolution when I save my document to a jpeg file from illustrator?

hey! I just came upon this thread and I have tried everyones solutions above but I'm still only getting 72dpi when I export as a JPEG, despite selecting 300dpi. What do you mean by the guidelines? Can u please attach a screenshot by any chance? Thanks heaps in advance.

Which Illustrator version do you use? How do you export? How do you check the resolution?

This is what worked for me:

1. Rasterize Image
2. Export > Export As
3. Format: JPG
4. Check “Use Artboards”

Also, I don't know if it matters, but these are my settings under JPG Options:

Quality: 10

Compression Method: Baseline (Standard)

Resolution: High (300dpi)

Anti-aliasing: Art Optimized (Supersampling)

The file only seems to save at 300dpi following this method if the color mode is set to RGB. In CMYK, it still saves at 72dpi. No idea why.
