Image to Base64 Encoder
/base64-image-encoderConvert images to base64 data URLs for inline use in HTML, CSS, and JSON payloads.

FAQ
Frequently asked questions
Everything you need to know about image to base64 encoder.
Why would I use a data URL?
Inline images eliminate extra HTTP requests, which is useful for small assets like icons, logos, sprites, or email-safe images.
Are large images a good idea?
Base64 inflates file size by about 33%, so it is practical only for assets under roughly 10KB. Larger images should stay as files.
How do I get the complete string?
The preview is truncated at 5000 characters for readability, but the copy button always copies the entire data URL.
Which formats are supported?
Any image type your browser can read. The MIME type is included in the data URL prefix, such as data:image/png;base64.
Is my image uploaded?
No. The file is read locally with the FileReader API and encoded in your browser, so it never leaves your device.
Where can I use the output?
HTML img src attributes, CSS background-image values, or JSON payloads that need embedded images without separate files.
