Frequently Asked Questions
Why would an image be Base64 encoded in the first place?
It's commonly used to embed small images directly in HTML, CSS, or JSON without a separate file request — convenient for small icons, though it increases the text payload size.
Is this tool free?
Yes, converting Base64 to an image is completely free.
Frequently Asked Questions
What input format does this accept?
You can paste either a raw Base64 string or the full data URI format (e.g.
data:image/png;base64,...). The tool automatically detects the format and handles both correctly.Is my data sent to a server?
No — this tool runs entirely in your browser using JavaScript. Your Base64 data is decoded locally and never sent to any server. This makes it safe to use with sensitive images.
What image formats can I decode?
Any image format that your browser supports can be decoded — including JPEG, PNG, GIF, WebP, and SVG. The tool wraps your Base64 data in a data URI and renders it directly in the browser.
Where do I get a Base64 string?
