Frequently Asked Questions
- What is Base64 encoding?
- Base64 encoding converts binary or text data into a safe ASCII string using 64 characters. It's commonly used in data URLs, APIs, and email attachments. This Base64 encoder and decoder runs in your browser — no server upload.
- Is my data sent to a server when I use the Base64 encoder?
- No. Encoding and decoding happen entirely in your browser. Your input never leaves your device, so it's private and secure.
- Can I decode Base64 strings with this tool?
- Yes. Paste a Base64 string and switch to Decode mode to get the original text. The tool detects and handles standard Base64 encoding.
