Your Base64 data never leaves your browser. Everything is decoded locally — nothing is uploaded to any server.
No waiting, no loading screens. Paste your string and the image preview appears in milliseconds.
Works with PNG, JPG, WEBP and GIF — with smart Auto Detect that reads the signature for you.
Instantly see image dimensions, format, Base64 size and estimated file size after conversion.
Copy the data URL, copy the raw Base64, or download the image directly in PNG, JPG or WEBP format.

Base64 is a method of encoding binary data, such as images, into a text format using a set of 64 characters (A-Z, a-z, 0-9, +, /). This is commonly used to embed images directly into HTML, CSS, or JSON without needing a separate image file. While encoding converts an image into a Base64 string, decoding (which this tool does) reverses the process — turning that string back into a usable image file.
See how a Base64 image string turns into a real downloadable image file. Paste your code, preview the result, and save it as PNG, JPG, or WEBP.
Add raw Base64 or full data:image Base64 code.
Check the decoded image before downloading.
Save the image as PNG, JPG, WEBP, or original format.
Common questions about decoding Base64 strings into image files.
A Base64 image is an image file converted into text format. It usually starts with something like data:image/png;base64, followed by a long encoded string.
Yes. If your Base64 string contains valid image data, you can decode it and download the output as PNG, JPG, WEBP, or original image format.
Your Base64 string may be incomplete, invalid, or copied without the correct image prefix. Try pasting the full data URL or a clean raw Base64 string.
This tool can decode images directly in your browser, so your pasted Base64 data does not need to be uploaded for simple preview and download.
Base64 images are commonly used in HTML, CSS, JSON, API responses, email templates, and database-stored image data.
