Encode and decode Base64 strings instantly
100% Private - Files Processed Locally
Your files never leave your device
Base64 shows up everywhere â embedding images in CSS, shipping binary data in JSON, you name it. This just encodes and decodes it instantly. One box to encode, one to decode, no fuss.
Paste in either direction and it converts on the fly. Everything stays in your browser.
Base64 is commonly used to encode binary data in text format. It's often used for embedding images in HTML/CSS, encoding authentication credentials, and transmitting binary data over text-based protocols.
Absolutely! All processing happens locally in your browser. Your data is never sent to our servers or any third party. However, note that Base64 is encoding, not encryption - it doesn't provide security.
Our tool supports text strings and Base64 strings up to 10MB. For larger files, we recommend using a dedicated file processing tool or splitting the data into smaller chunks.
Yes! Base64 encoding works with all ASCII characters, including special characters, whitespace, and binary data. The encoder handles all characters automatically.
Encode text to Base64 or decode Base64 to text
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It's commonly used to encode data that needs to be stored and transferred over media designed to deal with text.
