What is Base64 Converter?
Base64 Converter is a method of encoding binary data (like images, PDFs, or compiled code) into ASCII text.
It uses 64 characters to represent data: A-Z, a-z, 0-9, +, and /.
Why Do We Need It?
Computers love binary, but many transfer protocols were designed for text.
- Email: Original email protocols corrupted binary files. Base64 Converter makes attachments safe to send as text.
- HTML & CSS: You can embed small images directly into your code using "Data URLs" (e.g.,
src="data:image/png;base64,..."). This saves an HTTP request.
The Downside
Base64 Converter increases the file size by about 33%.
If you take a 100KB image and convert it to Base64 Converter, the resulting text string will be roughly 133KB. Therefore, it's great for small icons but terrible for large photos.
