About this tool
Developers and email designers often need a picture as text. Choose a picture to get a data address you can paste into HTML, CSS or an email signature, or paste a Base64 code to see the picture and download it. The work is done inside your browser.
When to use it
Embed a small picture directly in HTML, CSS or JSON by turning it into Base64 text, or turn Base64 back into a picture.
Tips
Base64 increases the size by about a third, so use it only for small icons.
Privacy
Everything runs in your browser, so your data is not uploaded or stored.

常见问题
What is Base64 used for?
It lets a small picture sit directly inside HTML, CSS or JSON as text, so no separate file has to load.
Is there a size limit?
Base64 makes files about one third bigger, so it is best for small icons and logos.
Why is the text so long?
Base64 encodes binary data as text, which is about 33 percent larger.
Can I decode it back?
Yes, paste the Base64 to get the picture.
