Image to Base64 in three steps
Convert a JPG, PNG, or WebP image into a complete Base64 data URL without uploading the source. The output begins with the correct image MIME type and can be copied directly into HTML, CSS, JSON, test fixtures, or small application assets.
Base64 is an encoding format, not compression. Its text representation is usually roughly one-third larger than the original binary file, and large embedded images can make source files difficult to maintain. Data URLs are most useful for tiny icons, placeholders, self-contained demos, email templates with compatible clients, and development fixtures. Regular image files remain preferable for larger website content because browsers can cache them independently.
File reading and encoding run in a dedicated browser worker, keeping the page responsive and the source on your device. FileGizmo displays the final character count and provides a direct copy action. The generated value is not sent to a server, logged, or stored by the tool.

Frequently asked questions
What does the output include?
It includes the MIME type and Base64 payload as a complete data URL.
Is the image uploaded?
No. File reading and encoding happen inside a local worker.
Does Base64 make files smaller?
No. Base64 is usually about one-third larger than the original binary file.
When should data URLs be used?
They suit small embedded assets; normal image files are better for larger content and browser caching.
