Uploaded file under 25MB – will reducing size affect quality?

Hello,
I have already uploaded my work to Adobe Stock as an EPS file. I made sure to reduce the size so that it’s under 25MB.
My question is Will reducing the file size below 25MB affect the quality for clients
Or is it fine since it’s saved as an EPS file?
I just want to confirm that buyers will still get the full quality when they download it.
Thank you!
