Why does my logo appear blurry after upload?

[sudibear]

Hello , Ive made a gif out of my logo. the text part of it is not animated however no matter what size I try to upload the text turns out blurry. I even see the preview gif before exporting it and it looks crisp but a soon as it is on shopify it gets super weird. im using blockshop theme

would appreciate any help

Can you send me the source of the file header.liquid . I will check and guide you to change it.
Because I checked and the logo image has been greatly reduced in size.

I have the same issue. If it's so common shouldn't Shopify address it!
