❓ Frequently Asked Questions
What is a Data URI?
A Data URI is a scheme that allows you to embed data (like images) directly into a webpage using Base64, instead of linking to an external file.
Are there file size limits?
While there is no hard limit, browsers may struggle with extremely large files (hundreds of MBs) as the Base64 string consumes significant RAM.
