Frequently Asked Questions

What is Base64 image decoding?

Base64 image decoding converts a Base64-encoded text string back into its original binary image data. You can paste a data URI or raw Base64 string and this tool will reconstruct and display the image.

What formats can I decode?

Any image format that was Base64-encoded can be decoded — PNG, JPEG, GIF, SVG, WebP, BMP, and more. If pasting a raw Base64 string (without data URI prefix), you can select the MIME type manually.

Is my data safe?

Yes. All decoding happens entirely in your browser. No data is sent to any server. The image is reconstructed locally using JavaScript.
