Do I need to include the data URI prefix?

No. The tool accepts both full data URIs (with the data:image/...;base64, prefix) and raw Base64 strings. If you paste raw Base64, the tool will attempt to detect the image format automatically.

What image formats can I decode?

The tool can decode any image format that was Base64 encoded, including PNG, JPG, WEBP, GIF, BMP, and SVG. The output download can be saved as JPG, PNG, or WebP.

Why does my decoded image look corrupted?

This usually means the Base64 string is incomplete or has been modified. Make sure you copied the entire string without any line breaks or extra whitespace that may have been introduced during copying.

Is there a maximum string length I can paste?

There is no hard limit imposed by our tool, but very large strings (representing images over 10 MB) may be slow to decode depending on your browser and device memory.

Base64 to Image Converter

Decode Base64 strings back to downloadable image files in JPG, PNG, or WebP.

Paste your Base64 string here

Base64 to Image conversion is the reverse process of encoding — it takes a Base64 encoded string and reconstructs the original image file for viewing, editing, or downloading. This is essential when working with APIs that return image data as Base64 strings, extracting embedded images from HTML or CSS source code, debugging data URI issues, or recovering images stored as text in databases and configuration files. Our free online Base64 to Image decoder processes everything locally in your browser, ensuring complete privacy for sensitive image data. Simply paste your Base64 string — with or without the data URI prefix — and the tool automatically detects the image format, generates an instant preview, and provides a download button. The decoder handles all standard image formats including JPEG, PNG, WebP, GIF, BMP, and SVG. It intelligently strips whitespace, line breaks, and common prefixes so you can paste directly from source code, API responses, or database exports without manual cleanup. Whether you are a developer debugging image encoding issues, a designer extracting assets from code, or anyone who needs to convert Base64 text back to a usable image file, this tool delivers instant results with zero configuration.

How to Convert Base64 to Image

Paste Base64 String

Paste your Base64 encoded string into the text area. Both raw Base64 and data URI format (data:image/png;base64,...) are accepted.

Preview the Image

The tool automatically decodes the string and displays an instant preview of the image so you can verify it looks correct.

Choose Download Format

Select your preferred output format. The original format is detected automatically, or you can choose PNG, JPEG, or WebP.

Download the Image

Click the download button to save the decoded image to your device as a standard image file.

Best Practices for Base64 to Image

Include the data URI prefix for automatic format detection
Remove any surrounding quotes or escape characters before pasting
Check the preview before downloading to verify correct decoding
Use PNG output format when you need lossless quality
For very large Base64 strings, allow a moment for the browser to process
