Question
1. Speed: What is faster in speed to send/receive images? Base64 or loading images via url
2. Data: what will take up more data on users phone?
3. Image clarity: what will give us a better image?
Answer
We have been asked this question before and it really depends on the situation and use case.
1. In depends on many factors.
2. Base64 encoding enlarges file sizes by up to 33%
3. If quality is your focus, I recommend URL/URIs.
I would love to hear more about this project and provide some more insight. Let me know if you have any other questions.
