Base64 Encoder
Email attachments and API bodies use Base64 to carry binary content as text. This tool converts your text into a Base64 string entirely in your browser. Do not encode real passwords; practice with samples first.
Step by step
- Prepare the short text to encode.
- Paste it into the input field.
- Click Encode and wait for the output.
- Copy the output into your target field.
- Decode it back to confirm no loss if needed.
Example scenario
Encoding Hello gives a string like SGVsbG8sIFV0aWdvIQ==. It travels safely inside a test API request. Everything runs in the browser; use sample sentences for trials.
Check your result
Verify the string holds only letters, digits, plus, slash and equals. Compare by decoding. If an API rejects it, confirm UTF-8 input.
Frequently asked questions
Is Base64 encryption?
No, only encoding. Anyone can decode it.
Non-English characters?
Yes, UTF-8 preserves them when decoded alike.
Encode files?
Suits short text and small test content.
Line length matters?
Usually not, but old mail systems wrap at 76 chars.
