Before Tableau Server, have ground rules, bare minimums or maximums for image file sizes, similar to this image below, a stock image from pexels from years ago, edited in Photoshop, and optimized the image quality to ensure it’s not a large file on the frontend of my website.
Otherwise this web page would load slower, and cause the ranking to decrease.
I recently optimized 2.9k image, that’s 3000 images, bulk automated optimization.. To help a local store e-commerce website. In an attempt to migrate and increase ranking.
We are transitioning from files that are 500kb to 1mb – down to sizes of <60kb. It helps reduce speeds of the dashboard if done correctly!!
The migration website was “so much better” the owner asked me to turn it off. The optimization of the images was recognized by the algorithm and it ranked better than their content.
Similar to rivalries in Tableau environments, the best dashboard gets the most clicks and those are often the dashboards that do not require a lot of waiting.

Optimize Images in Tableau and Help End Users

Four best practices or steps to optimize images in Tableau Desktop.
Optimize Images in Tableau Desktop – Like Rocky!
- Do away with massive quality pictures, and optimize the image
- Drop the ratio size if it’s massive, or your file will not be optimized
- If you can’t tune it beyond 30kb – we prefer to find a better image – hero’s we look to stay under 100k.
- Heroes are the big header image want to keep those from being pixelated, and people are more relaxed for those from a file size perspective.
- Even little pictures need to scale down – we use photoshop!
- A resized image is an unoptimized image
Optimizing Images Steps Explained
#1 Drop big quality pictures. They have free apps on the phone that optimize and compress image file sizes instantly or hire someone that uses photoshop for a living.
#2 If the file is bigger resolution than the dashboard, you’re asking your software to resize it for you, this is unnecessary – bring the file in at the appropriate canvas size.
#3 We may be biased here, but we do have a standard for production released content – we always peel back significant file sizes to avoid perpetually slow workbooks. Shaving off 1-second thousands of times a day is a big number.
#4 If you are resizing the image in Tableau Desktop, you should bring it in at that size to increase the speed of the workbook.
Your average enterprise website is <3mb per page. They never release images on their website before optimizing the file size. We prefer doing POC’s with whatever size and start optimizing the image in tableau desktop after everyone signs off on this being the right direction.
Just in case we want to swap pictures – we won’t lose a lot of work! Optimizing Images is Extremely Important, so put your gloves on!
