About Base64 to Image

Base64-encoded images appear in HTML emails, CSS stylesheets, API responses, and self-contained documents. When you need to inspect or extract those embedded images, Xevon Tools' Base64 to Image decoder makes it simple. Paste the data URI string into the text area and the tool instantly decodes and previews the image. The format is detected automatically from the MIME type prefix, supporting JPG, PNG, GIF, and WebP. One click downloads the decoded image as a proper file with the correct extension. This is invaluable for debugging inlined assets in email templates, inspecting API payloads that return Base64 image data, and recovering images from self-contained HTML documents. Everything runs in your browser with no server involvement, so even sensitive or confidential images remain private throughout the process.

Frequently asked questions

The tool supports JPG, PNG, GIF, and WebP data URIs. The format is detected automatically from the MIME type prefix in the string (e.g., data:image/png;base64,...).
Including the full prefix (data:image/png;base64,...) is recommended so the tool can detect the format automatically. If you paste raw Base64 without a prefix, the tool will attempt to decode it as PNG by default.
There is no hard limit, but very long Base64 strings (from images larger than a few megabytes) may slow down the browser. For most practical use cases the tool handles the input without issues.
Yes. Use the companion Image to Base64 tool to upload an image and get the data URI string.
