Base64 Converter

Encode or decode UTF-8 text as Base64 via Toolomix servers (ConvertToBase64 / DecodeFromBase64)—encoding, not encryption.

Tips

Server-side encode and decode

Encode and decode POST your text to Toolomix. This is not a browser-only converter for those actions.

Encoding is not encryption

Anyone can decode Base64 without a key. Do not treat it as a way to protect secrets.

Line wrap and JSON display

Line wrapping and optional JSON pretty-print after decode can run in the browser for display; the core conversion still uses the server endpoints.

Encode on Toolomix

POST /web-tools/ConvertToBase64 turns UTF-8 text into Base64.

Decode on Toolomix

POST /web-tools/DecodeFromBase64 turns Base64 back into text.

Display helpers

The UI may wrap lines or pretty-print JSON after decode locally for easier reading.

What this tool does

Base64 Converter encodes UTF-8 text to Base64 or decodes Base64 back to text.

It uses Toolomix server endpoints for encode and decode. Base64 changes representation only—it does not encrypt data.

How to use

Choose encode or decode

Select encode for plain text, or decode for a Base64 string.

Paste your input

Enter the UTF-8 text or Base64 payload you want to convert.

Convert and copy

Run the conversion, optionally adjust display wrapping, then copy the result.

Supported inputs and output

Input: pasted UTF-8 text (encode) or a Base64 string (decode). Output: Base64 text or decoded plain text.

Primary workflow is pasted text, not a dedicated binary file-upload converter.

Processing and privacy

Encode and decode send your content to Toolomix via POST /web-tools/ConvertToBase64 and POST /web-tools/DecodeFromBase64.

Client-side line wrapping or JSON pretty-print after decode is for display only. See the Privacy Policy for how requests and logs are handled.

Limitations

Known limits

  • Not encryption or access control
  • Requires a successful Toolomix response for encode/decode
  • Invalid or truncated Base64 will fail decoding
  • URL-safe Base64 alphabets may need conversion before decode

Troubleshooting

If decode fails, confirm the string uses a standard Base64 alphabet, includes expected padding, and was not truncated.

If the request fails after a valid-looking input, retry and read the on-page error—encode/decode depend on the Toolomix endpoints responding.

Frequently Asked Questions

Is Base64 the same as encryption?

No. Base64 is a reversible encoding. Anyone who has the string can decode it without a secret key.

Does encode/decode run only in my browser?

No. Encode and decode call Toolomix at /web-tools/ConvertToBase64 and /web-tools/DecodeFromBase64. Your input is sent to the server for those actions.

What character encoding is used?

Text is handled as UTF-8 for encode and decode.

Why does my Base64 string end with =?

Padding characters make the encoded length valid. Trailing = signs are normal for standard Base64.

What are the exact API paths?

Encode uses ConvertToBase64; decode uses DecodeFromBase64. There is no ConvertBase64 endpoint for this tool.

Can the UI wrap lines or format JSON?

Yes. After a successful decode, the client may wrap lines or pretty-print JSON locally for display. That does not replace the server conversion step.

Why did decoding fail?

Invalid characters, missing padding, truncated strings, or non-Base64 input will fail. Check the on-page error and retry with complete standard Base64.
