Frequently Asked Questions
Is Base64 secure for encrypting passwords?▼
NO! Base64 is not encryption. It is an encoding format designed to transport binary data over text-only protocols. Base64 strings can be decoded by anyone in milliseconds.
Does this tool support international unicode characters and emojis?▼
Yes! Our implementation uses UTF-8 byte serialization to ensure non-ASCII characters and emojis encode and decode with zero corruption.
Are my encoded strings logged on your servers?▼
No. All processing is executed 100% locally inside your web browser.
What is the "=" symbol at the end of Base64 strings?▼
The "=" sign is a padding character used when the input data length is not evenly divisible by 3 bytes.
