Base64 Encoder

The Base64 Encoder converts plain text into Base64 so it can be safely transported in URLs, headers, or compact payloads. Use it when you need a quick way to encode snippets without installing command‑line tools.

Key features

• Fast, in‑browser Base64 encoding with Unicode support
• Two‑panel layout with Copy, Clear, and Sample actions
• Local persistence so your last input is restored
• Keyboard accessible controls and ARIA‑labeled inputs

Common use cases

• Encoding small text payloads for data URIs
• Preparing values for query params or form fields
• Transforming snippets before sending to APIs

Privacy & security: everything runs locally in your browser. Do not paste secrets into sites you do not control.

1. Paste or type your text into the left panel.
2. The right panel shows the Base64‑encoded output instantly.
3. Click “Copy Output” to copy the encoded string.
4. Use “Sample” to load example content and verify behavior.
5. Use “Clear” to reset both panels.

Tips

• Encoding Unicode is supported; emojis and non‑Latin scripts work.
• For decoding, open Base64 Decoder.
• For URL‑safe encoding, replace + with - and / with _.

Troubleshooting

• Output is empty → The input panel is blank; enter text.
• Service rejects characters → Some systems expect URL‑safe Base64; swap characters as noted above.
