Developer tool guide
Encode Unicode text to Base64 or decode it back
Convert text into Base64 for transport in text-based systems, or decode a Base64 string into readable text. Unicode characters are supported by the browser-side conversion.
Base64 is an encoding format, not encryption. Anyone with the encoded value can decode it, so it should not be used to protect secrets.
How to use Base64 Encoder
- Paste text or Base64.Enter readable text for encoding or a Base64 value for decoding.
- Choose Encode or Decode.Select the direction that matches your input.
- Review the converted value.The result appears beside the input; malformed Base64 produces an error.
- Copy the result.Copy the output for use in code, tests or configuration.
Practical ways to use this developer tool
Inspect an encoded value
Decode a Base64 string received from an API or configuration.
Create test fixtures
Generate sample encoded values while developing an integration.
Check round trips
Encode text and decode it again to confirm the original value.
Behavior, privacy and limitations
- Not encryption: Base64 obscures nothing and provides no confidentiality.
- Text-focused: this interface accepts pasted text rather than binary file uploads.
- Valid input required: decoding fails when the supplied value is not valid Base64.
- Private processing: encoding and decoding happen locally in your browser.
Frequently asked questions
Is Base64 encryption?
No. It is a reversible text encoding and should not be used to secure sensitive information.
Does it support accented and non-Latin text?
Yes. The tool converts Unicode text before applying Base64 encoding.
Can I upload a file?
No. This version works with text pasted into the input area.
Why does decoding show an error?
The input may contain invalid Base64 characters or an incomplete encoded value.
Does Toolyma store my text?
No. The conversion runs locally in your browser.
