About Base64 Image Decoding
Base64 to Image decoding converts text-encoded image data back into a visual image file. This is the reverse process of Base64 encoding and is essential for developers working with encoded image data.
The tool accepts both raw Base64 strings and complete data URIs (with the data:image/... prefix). It automatically detects the image format and renders a preview before downloading.
Common uses include extracting images from API responses, email source code, CSS stylesheets, and database entries that store images as Base64 text.

Frequently Asked Questions
What Base64 formats are supported?
Both raw Base64 strings and data URIs (data:image/png;base64,...) are supported. The tool automatically detects the format and handles both correctly.
Can I decode Base64 strings without the data URI prefix?
Yes. If you paste a raw Base64 string without the data: prefix, the tool will attempt to decode it and detect the image type automatically.
Why does my Base64 string produce a blank image?
The Base64 string might be corrupted, truncated, or not represent valid image data. Ensure you have the complete string including any line breaks or padding characters (=).
Is there a size limit for Base64 strings?
There is no fixed limit. However, very large Base64 strings (representing images over 50MB) may be slow to process depending on your device's memory.
