Questions people ask
What is a Base64 image good for?
It lets you put a picture inside your code, so the page needs no separate file request. It suits tiny icons and logos in HTML emails, CSS or JSON.
Why is the text longer than the file?
Base64 turns every 3 bytes into 4 characters, so the text is about one third bigger than the image.
Should I use Base64 for large photos?
No. Large Base64 strings slow the page and cannot be cached on their own. Use them for images under about 10 KB and compress the picture first.
Is the picture uploaded?
No. It is read and encoded in your browser.
