Base64 Encoding

Estimated reading time: 1 min

The Base64 encoding is a common technique used to convert files like images, videos, or documents into a format with only letters, numbers, and symbols. 

Some systems have a limitation on the types of data they can take like emails or URLs. Base64 encoding allows you to convert binary data (0,1) into a text format that these systems can understand. 

  • Embedding Images in Emails: Some email systems, like Gmail, do not allow directly embedding images. Base64 encoding allows you to convert the image into text, ensuring that it arrives safely within the email body. 
  • Storing Data in URLs: URLs have limitations on what characters they can contain. Base64 encoding helps represent various data types within a URL without breaking it. 
  • Data Transmission within Apps: Many mobile apps rely on Base64 encoding to transmit various data types (like images or user information) securely within the app’s communication channels. 
Things to Remember: 
– Base64 encoding makes the data larger (about 33% larger). 
– It’s not a primary security measure on its own. 
– It’s a common technique for data transmission and storage in various applications.

For example, if you want to send an attachment file within your Gmail Method, follow the steps below:  

Let’s go to https://www.base64encode.org , to encode your file into Base64 first. 

Go to this section:  

Select your file then 

  • Click on the button ENCODE 
  • Under the Encode button, click on “CLICK OR TAP HERE” to download your encoded file. When you open that file, you will get something similar of this: 
  • Now you can Copy these Characters and use them in Wiresk to send files (in fields “content(base64)”.
