Base64 to Image Converter

A Base64 to image converter decodes a Base64 string or data:image URL, previews the picture and lets you download it as a file with the matching extension. Raw Base64 without a prefix is treated as PNG, and decoding runs in your browser.

This tool decodes any base64 image data, whether it's a full data URL (data:image/png;base64,…) or just the raw base64 characters, and shows you the resulting image with a download button. It's the reverse of embedding: sometimes you have a base64 string — pulled from an API response, a database export, or someone else's code — and need to actually see what image it represents, or save it as a real file.

Paste the string and decode: if it's a valid image, you'll see it rendered immediately, along with a button to save it as a proper image file (with the correct extension inferred from the format). If the data isn't valid image content, you'll get a clear error rather than a blank result.

This is a common debugging step when working with APIs that return images as base64 (common in some backend responses, PDF-embedded images, or webhook payloads) — decoding here lets you quickly verify the image is what you expect before writing code to handle it. Decoding happens entirely in your browser; the string you paste is never sent anywhere.

It's also useful for recovering an image buried inside a JSON export, a saved chat log, or a config file where someone stored an icon as an inline string instead of a separate asset — paste the relevant field's value here rather than writing a one-off script just to look at a single picture.
