My EPS is 19 times bigger than my AI

[JuDrus]

Hello,

I created a simple logo and my eps folder is huge...

The size of AI file is 386kb, but the same file of EPS is 7.22mb...

Did action to Delete Unused Panel Items, but that didn't do much...

Should it be like that or can I reduce that size?

What exactly is in the file? Any linked images, sketches? effects? transparency? How many path and points?

Which options did you select when saving?

[JuDrus]

What exactly is in the file?

• Logo

Any linked images, sketches? effects? transparency? How many path and points?

• How can I find all this info?
• Also, there are no linked images, because the logo 100% made with illustrator. 

Which options did you select when saving?

• File > Save As... > Save as type: Illustrator EPS (and checked Use Artboards)

You should know which functions you used to create the logo. Please tell us.

The number of paths & points is in the document info panel.

What does your logo consist of?

And then there are a couple more options in the EPS options.

[JuDrus]

Ok, now I created even simpler logo and it is 5.55mb.

It contains only 1 color (#111111) without any effects, gradients or transparency.

This is info about that logo:

And this is how I save all my EPS. I think it's the default, because I haven't touched these options.

Actually, it would be best to just let yourself off that hook and forget EPS as a file format. It's obsolete, worthless in modern workflow, and you don't need it. If you do happen to run into one of the terribly rare and antiquated reproduction processes that still require it (you won't), find a better service provider that utilizes current technology, or just submit the 7.22 MB file.

So what should be my logo files?

Now I am working on 2000x2000 pixel artboards and then resize them based on logo created.

For example, if the logo is horizontal then artboards would be 2000x500 or 2000x900 or 2000x1500 and etc. 

Also, I always leave 100px space around the logo. If the logo is 1800x750, then the artboard would be 2000x950.

Then for raster files, I am exporting to JPEG and PNG.

For vector, I am saving as AI, EPS, and PDF.

Of course, you govern your own workflow, but some points to consider:

"I am working on 2000x2000 pixel artboards"

Pixels are a relative unit of measure. Logo design groundwork should be primarily print-centric, with on-screen applications adaptable subsequently. In that sense, it's better to employ an objective, constant unit of linear measure. "Pixels" can't ever give you a sense of how the relative weight of a logo's elements will be affected at, say, business card size vs. on a vehicle wrap.

"I always leave 100px space around the logo"

In vector graphics (and logo design, fundamentally), this is meaningless and unnecessary. Of course if you find it useful in subsequent raster export routines, so be it.

"So what should be my logo files? For vector, I am saving as AI, EPS, and PDF."

Well, you have your AI source file and PDF for deployment; there is no need for EPS.

So I should start using millimeters instead of pixels? Maybe you could give me advice, what size artboards I should be using in mm?

Talking about logo files. What about SVG files? Are they useful and should I include them?

[Ton Frederiks]

In Illustrator points and pixels are the same size, 1/72 of an inch.

As long as you remember that, there is nothing wrong with using pixels.

[Monika Gause]

SVG - scalable vector graphics. You might want to read about in Wikipedia.

Whether to deliver it or not depends on where the logo will be used. Also: Before exporting it, you might need to have some discussions with web devlopers, because how exactly to build the SVG depends on what exactly will be done with it.

[Ton Frederiks]

I think that the tiff preview in the eps is the main cause for the large file size.

Try to scale the art (and the artboard) to 25%.

You will notice a decrease in filesize.

If the logo contains only simple vectors, it does not affect the quality and remains scalable.
