$ cat FAQ.md
What Base64 formats are supported?▶
You can paste either a raw Base64 string or a full data URI (e.g., data:image/png;base64,...). If you paste raw Base64, the tool assumes PNG format.
Is my data sent to a server?▶
No. The decoding and rendering happen entirely in your browser. Your Base64 data never leaves your device.
Can I download the decoded image?▶
Yes. Once the image preview is displayed, click the download button to save it as a file. The format is automatically detected from the data URI.
