FAQ
What input formats are accepted?
Both raw Base64 strings (e.g., iVBORw0KGgo...) and complete Data URIs (e.g., data:image/png;base64,...) are accepted.
How does auto-detection work?
The tool examines the first few characters of the Base64 string to identify the image format (PNG starts with iVBOR, JPG with /9j/).
Is there a size limit?
No hard limit since processing happens in your browser. Very large strings may be slower.
Is my data sent to a server?
No. Everything is processed locally in your browser.
Can I decode non-image Base64?
This tool is specifically for images. For general Base64 text decoding, use a text Base64 decoder.
