The best! Using it in the backend
October 30th, 2025
Hi and thank you. The plugin is great. I am using it in the backend to convert images to base64. Only improvement I would like to see is split the output into two parts: mimeType and base64. I had to do "result of: base64: split by (,): item#2" to get only base64. Best
Thank you for your comment and suggestion! This update will certainly be implemented to address a need I hadn't previously identified 😁 (plugin author)
