About the Online Base64 Encoder/Decoder
How to Use the Tool
- Select the desired conversion tab: 'Text to Base64', 'Base64 to Text', 'Image to Base64', or 'Base64 to Image'.
- For text to Base64 encoding, enter your text in the input field and click 'Encode'. The tool supports UTF-8 and other character sets.
- For Base64 to text decoding, paste your Base64 string into the input area and click 'Decode' to see the original text.
- For image to Base64 conversion, simply drag and drop an image file or click to upload. The tool will generate a Base64 data URI.
- For Base64 to image decoding, paste a valid Base64 image string and click 'Decode' to preview and download the image.
- Use the 'Copy' button to quickly get the result to your clipboard.
Frequently Asked Questions
Q: What is Base64 encoding?
A: Base64 is an encoding scheme that converts binary data into a radix-64 representation, which is made up of 64 basic ASCII characters. It's used to ensure that data remains intact without modification during transport through text-only channels.
Q: Is Base64 the same as encryption?
A: No, Base64 is an encoding method, not encryption. It is easily reversible and does not provide security. For data protection, use encryption algorithms like AES.
Q: How to convert image to Base64?
A: You can use the 'Image to Base64' tab. Upload your image, and the tool will automatically convert it into a Base64 string, which you can use in HTML `<img>` tags or CSS `background-image` properties.
Q: Why is my Base64 string not decoding?
A: This can happen if the string is not a valid Base64 sequence. A valid string should only contain `A-Z`, `a-z`, `0-9`, `+`, `/` characters, and might have `=` for padding at the end. Check for any invalid characters or corruption in the data.
Q: What is a Base64 data URI?
A: A Base64 data URI (or data URL) is a scheme that allows you to embed files, like images, inline in web pages. It starts with `data:image/[MIME_type];base64,` followed by the Base64-encoded data.
