Encoding the image content into Base64

Images available on the internet or stored locally can be analyzed for explicit content by converting their data into a Base64 string format and using the Google Cloud Vision API.

1. Encoding web images:

Use the Utilities by Quickwork app’s Convert file content action.
Follow this guide for detailed instructions.

2. Encoding locally stored images:

Visit https://www.base64encode.org/.
Scroll to the Encode files to Base64 format section.
Select the image file from your device and click Encode.
Once encoded, download the Base64 content as a text file.

Note:
Ensure you use the Base64 content of the image, not the Base64 URL of the image.
