Image to Base64
Encode an image as Base64 or a data URL directly in the browser with copy and download actions.
Turn an image file into a Base64 string you can paste into CSS, JSON, HTML, or tests.
Everything runs locally in your browser. Larger files take longer to process.
Select or paste the source content, adjust any settings you need, and run the tool to see the preview, downloads, and copy actions here.
About the image to base64
How this tool works
Encoding an image to Base64 is a common bridge between design assets and developer workflows. This page keeps that bridge small, local, and copy-friendly.
You can choose either a full data URL or the raw payload, which covers most markup, CSS, JSON, and test-fixture use cases.
Where it is useful
The result panel is designed to surface the long output cleanly while still giving you a download fallback if you do not want to copy it directly.
This same pattern should scale well into later developer-facing file utilities because the output model is already structured for copy and download actions.
- Generate inline image strings for HTML, CSS, or email templates.
- Create test fixtures from small icons and screenshots.
- Copy either raw Base64 or a full data URL without extra tooling.
