Frequently asked questions
Quick answers for developers landing here from search.
What is Base64 encoding used for?
Base64 turns binary data into ASCII text. Developers use it for embedding assets, sending payloads via JSON, or authenticating APIs.
Does this tool support Unicode text?
Yes. It uses the browser's TextEncoder/TextDecoder APIs so emojis and multi-byte characters round-trip without corruption.
How can I decode Base64 safely?
Paste a string into the Base64 panel and click Decode to see the original text. The tool ignores whitespace and accepts URL-safe Base64.
