I suspect the problem is with the actual Base64 data. Otherwise it looks good to me. See this fiddle where a similar scheme is working. You may try specifying the character set.

You need to specify the correct Content-type, Content-encoding and charset.
Like
data:image/jpeg;charset=utf-8;base64,
according to the syntax of the data URI scheme:
data:[<media type>][;charset=<character set>][;base64],<data>

r/webdev on Reddit: Displaying a BASE64 image from the address bar as HTML
December 28, 2021 -
Sorry if this doesn't make sense. I'm not a webdev and am learning as I go.
I found an app to convert a GIF into a BASE64 image, and can display that image directly in a browser from the address bar:
data:image/webp;base64,UklGRkoBAABXRUJQVlA4ID4BAABQGQCdASoAAQABPmk0mk0hkQj4FANAbuF0ZgEtoORb8gfQOSPZX+2EgESEaTOSPZ6DxKSajiULSzpGo4lJNDzXQeJSTUcK5r8qGlHjl2D9vhlNxaqqqqqqqqqoL6VDSjxy7B/jQpFZdgjdfIZuvkMxg0br5DN18hm6+QzdLRAHczR3KfRt3MFQHcsDcSANwYmceQBWXYI3XyGbpby08Bm6+QzdfIZuvb23VLW0APFyIwSGyg8MoGZ1CWupEZTcWqqqqqFAEjCoBJNQpYdi80ajiUIAAP7+Esv2C28v//g1vuG/VBMAAAAZ65KNgQJL55Z9Kf7wVb1kgNzlgIUCZkIXounFlBEEAAAAXasZLom8qUayYpxZQNd/OqdYmNk1M4YgqR+3YuyBsC8XmKKxMjcoxBenFECuAAAAAAAAAAA=
However, is there a way to either plug this into a <script> tag, or force something to read it as HTML? The particular instance would be plugging this in as an HTML address on an NFC card or QR code, so when that's scanned it just displays the BASE64 image in the browser as opposed to going to a website. If I just put that in an address field on either one of those media, the iPhone will say "no valid data" because it's looking for the https.
Then, if there is a way to do this, is there a way to resize it from that same syntax in the browser? Like, if it was a 128x128px image, is there syntax to tell the browser to display it at 600x600?
Thank you in advance!

this works, however you will need an html page, that you can host for free on github pages: Just put the base64 in the url in a parameter called p Like this: somePageYouHost.github.io/my.html?p=iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO9TXL0Y4OHwAAAABJRU5ErkJggg== In that page just puth this simple html ![]()
