Frequently Asked Questions
Can I decode images?
This tool displays the decoded result as text. For images, use our "Base64 to Image" converter.
Is it local?
Yes, decoding happens in your browser.
What character set is used?
We assume UTF-8 encoding. Non-standard characters might look different if encoded in other charsets.
