Frequently Asked Questions
Do I need to include the data URI prefix?
No. If you paste a bare Base64 string the tool inspects the decoded bytes for a PNG, JPEG, GIF or WebP signature and works out the format itself.
Why does my string fail to decode?
Usually truncation — Base64 must be a multiple of four characters, and copying from a console or database viewer often cuts the end. Line breaks and spaces are fine; the tool strips them.
Is my Base64 data sent to a server?
No. Decoding happens in your browser with the built-in atob function. Nothing you paste is transmitted, which matters when the string came from a private API response.
What image formats can it decode?
Anything your browser can display: PNG, JPEG, GIF, WebP, BMP, SVG and AVIF where supported. The decoded MIME type is shown so you know what you have.
Decoding runs entirely in your browser. The Base64 string you paste is never transmitted or logged, so it is safe to inspect data from a private API response.
