Decode base64 to image in Alteryx?

[Amir_Hamzah]

Hello everyone!

Based on the discussion in the community, I have found out that we can encode or decode any strings or table through base64.

So, I just wondering if is there any ways we can encode/decode base64 for any image file using Alteryx Designer?

Thank you.

You can use the blob convert tool to move from blob to base64 and vice versa. Additionally, the blob input and output tools may be of use when working with images. Finally, you may want to use the Image tool in the Reporting category if you would like to use an image in an output alongside other reporting elements.

Hi Brandon. 

Thank you for the help! It really does help me to encode/decode my image to base64.

I have one more question.

I have tried this workflow and discovered that I could only decode base64 to an image if the original file (image) is smaller than 1MB. Do you have any thoughts on why this happened or is there anything wrong with my workflow?

I have attached a workflow with both large and small size of images in it.
