Frequently asked questions
Why would I convert an image to Base64?+
Base64 data URIs let you embed small images directly inside HTML, CSS, or JSON without a separate file request, which is handy for icons, emails, or single-file demos.
Does Base64 encoding increase file size?+
Yes, roughly by about 33%, since Base64 encodes binary data as text. It's a trade-off for embedding convenience, not a compression method.
Is this good for large images?+
No, Base64 embedding is best for small images like icons and logos. Large images should stay as separate files for better caching and load performance.
