Frequently Asked Questions
What is a Base64 image string?
A Base64 image string is binary image data encoded as ASCII text. It often appears as a data URI like data:image/png;base64,iVBOR... and is used to embed images directly in HTML, CSS, or JSON without separate files.
What formats are supported?
This tool supports PNG, JPEG, GIF, WebP, SVG, BMP, and ICO. The format is auto-detected from the data URI prefix or the decoded binary signature.
What does 'invalid Base64' mean?
This error means the input string contains characters not valid in Base64 encoding (A-Z, a-z, 0-9, +, /, =). Check for extra whitespace, line breaks, or truncated strings.
Is my data secure?
Yes. All decoding happens entirely in your browser using native atob() and Blob APIs. No data is sent to any server.
