Base64 to Image

Free Base64 to Image Converter — Decode & Preview Instantly

Base64-encoded images appear in API responses, HTML source code, CSS stylesheets, database records, and configuration files. When you encounter a long string starting with data:image/png;base64, or just a raw Base64 string from an image, this free Base64 to Image Converter decodes it back to a viewable, downloadable image instantly — all in your browser without uploading anything to a server.

Paste any Base64 string (with or without the data URI prefix) into the input and click Convert. The decoded image renders immediately for preview. Download it in its original format (PNG, JPG, GIF, WebP) with one click.

The reverse direction is also supported — upload any image file to encode it as Base64, with the option to include the complete data URI prefix (data:image/png;base64,) for direct embedding in HTML or CSS. This is useful for embedding logos, icons, and small images directly in emails and standalone HTML files.

Base64 Image Use Cases

HTML email. Many email clients block externally hosted images. Embedding images as Base64 ensures they always display, even without external requests.

CSS backgrounds. Small icons and patterns can be embedded directly in CSS as Base64 data URIs, eliminating extra HTTP requests for tiny assets.

API payloads. REST APIs that return or accept image data often use Base64 encoding since JSON cannot contain binary data directly.

Debug and inspect. When reviewing API responses, database records, or code that contains Base64 strings, this tool lets you quickly visualize what image is encoded.
