Toolkit / Developer Tools
Base64 Encode / Decode
Encode text to Base64 or decode Base64 back to readable text for quick debugging, API work, and data inspection.
Privacy note: Developer inputs are handled locally for supported tools. Avoid pasting production secrets, private keys, or credentials into any tool unless you understand the risk.
Limitations: Invalid Base64 input may not decode cleanly.

How base64 encode / decode works
Paste text or Base64 input and Toolkit shows the encoded and decoded forms.
Base64 is an encoding format, not encryption, so decoded content should be treated as plain text.
Privacy
Developer inputs are handled locally for supported tools. Avoid pasting production secrets, private keys, or credentials into any tool unless you understand the risk.
Limitations
- Invalid Base64 input may not decode cleanly.
- Base64 increases data size compared with the original bytes.
- Do not use Base64 as a security measure for secrets.
FAQs
Is Base64 encryption?
No. Base64 is reversible encoding and does not protect data.
Why is Base64 used?
It makes binary or special-character data easier to embed in text-based formats and APIs.
Why does decoded text look wrong?
The original data may not be UTF-8 text, or the Base64 string may be incomplete or invalid.
Can Base64 store files?
Files can be represented as Base64, but the encoded data is usually larger than the original file.
