Encodes text into Base64 format or decodes it back from Base64. UTF-8 (including Turkish characters) is supported, and the operation runs entirely in your browser.
What Is Base64?
Base64 is an encoding method that converts binary or text data into a string made up only of ASCII characters. It is not encryption; its purpose is not to hide data but to transport it safely through text-based media (email, JSON, data URIs).
Where Is It Used?
- Embedding small images directly into CSS/HTML (data URI).
- Encoding email attachments (MIME).
- Simple authentication headers in APIs (Basic Auth).
- Carrying binary data inside text formats such as JSON.
How to Use It
- Type or paste your text into the left field.
- Use Encode to encode it and Decode to decode it.
- Copy the result.
Warning: Base64 is not a security measure; anyone can easily decode it. To protect sensitive data, use real encryption methods.
Frequently Asked Questions
Is Base64 secure/encrypted?
No. Base64 is only an encoding; no key is needed to decode it. It should not be used for confidentiality.
Are Turkish characters decoded correctly?
Yes. This tool is UTF-8 compatible; characters such as ç, ş, ğ, ı are preserved during both encoding and decoding.
