EPS file size

[JuniperCo]

I’m stumped on something and looking for an explanation. I have a simple one color logo saved as an eps. The file size is less than 30kb. My client needed to upload a file for production of promotional padfolios that were going to be debossed. The upload required a file 500kb or higher. I couldn’t figure out any way to get a vector file over 50kb. I emailed the company the logo and they sent back an ai file that was 1.2mb. What am I missing here? How do you think they created a larger file?

Hi @JuniperCo and welcome to the forums,

I'm a little baffled as to why the upload requires a file of 500kb or higher, where are they uploading the file to exactly. At the end of the day, the file size is the file size, you can't practically make a 30kb file larger without adding elements to it.

The .ai file is Adobe's proprietary format and will contain additional information as it is designed as an interchange format for use between different Adobe software. EPS is a very outdated format these days.

At the end of the day, logically the client should simply be able to email your .eps or the .ai file to the company producing the promotional padfolios. The likeliehood is that their online upload facility necessitates a minimum upload file size of 500kb so what you could do is to Zip your .eps file along with their .ai file to make a file large enough to meet their minimum size requirements.

I was also confused by the requirement. They didn’t give any raster upload options, so I don’t know why the file size would matter. I don’t use Adobe right now, because I only design very part time and can’t justify the subscription cost. They sent me back an ai file that was larger and I’m curious how they got it to increase because in affinity there was nothing I could do to make it larger. 
 

Side note, if eps is becoming dated, what is the best way for affinity users to deliver files?

It’s been a while since I’ve used illustrator and if anything I was trying to decrease file size. Does illustrator just generate larger file sizes or have additional settings that could increase it?
