- What formats does this tool accept?
- You can paste a full data URL (starting with 'data:image/...;base64,') or a raw Base64 string without the prefix. If you paste raw Base64, the tool assumes PNG format. Supported image types include PNG, JPEG, GIF, WebP, and SVG.
- My Base64 string is not decoding correctly. What should I check?
- Make sure the string is complete and has no extra whitespace or line breaks in the middle. If it came from a data URL, you can include the full header or strip it down to just the Base64 portion. Base64 strings must have a length that is a multiple of 4 (padding with '=' characters as needed).
- Is my data sent to a server?
- No. Decoding happens entirely in your browser. The Base64 string you paste never leaves your device.
