Encode and decode Base64
Converts UTF-8 text to Base64 and decodes Base64 back to text.
Encodes text to Base64 and back, handling UTF-8 properly so accents and special characters survive.
How it works
- Choose the direction: encode or decode
- Paste your text
- Copy the result
Runs in your browser. Base64 is an encoding, not encryption — anyone can read the content back.
Frequently asked
What does it cost?
Every tool shows its price before you start. Tools marked free run in your browser and never cost anything — no sign-up needed.
What happens if processing fails?
You are not charged. We only charge when a result is actually produced; if the run fails, the charge is reversed.
What happens to my files?
Uploaded files are processed in memory for that one request and then discarded. We do not store them, and their contents never reach our logs or analytics.
Do you use my own API key?
No. Your BYOK key belongs to the Playground and is never used for these tools.
