JPEG EXPORT - options don't change a thing

[cmeed]

I just had another go with compression all the way down. no file size difference and no difference in quality

repeating this i when through to the window i attached and the slider had gone back to nine

this makes me think it changed bacjk to a previous setting

change the pixel dimensions to affect file size.. not resolution.

i'm not sure what's up with the jpg compressor (i've just always had mine set to 10).. i'll check it out in a bit.

thank you.....

Compression doesen't do a thing?

i think you're right.

it makes no difference if i have it set to 1 or10.. same file size and the image looks identical.

[cmeed]

So I'm not going mad.....
what to do though??
Is this a Mac thing? I'm Mac your Mac

thom thom that was just compression you where changing?

[jeff hammond]

i just tried it using sketchup 7 as well.
same thing -- there's no difference at all with different compression settings.

might be worth filing a report to the google team.

Yup!

I've reported this to the Google folks. Hopefully, it will be a quick fix.

On my Mac and surprisingly, the PNG export file is about a third the size of the JPEG - its usually the other way round when I export images from other apps.

[cmeed]

did anybody get any answers for this?

PNG can be smaller than JPG. It all depends on the colourfulness of the image. With less, "pure" colours,png's are smaller but with more complex colour scenes/schemes (like photos), jpg's can be smaller.

It all depends on what you export. If you export with image textures, I bet a jpg will be smaller. If you export in some monochrome, hidden line or even shaded (without textures), png might have the chance to be smaller.
