Why does the speed when I'm building a form is too slow?

I'm building a form with images and it's so slow to make changes and add new boxes. I mean the speed it's terrible. I think I made a bad decision upgrading my plan because I don't feel better performance of the platform.

 

Thanks!

I have checked your form and I can see what you're referring to, but I can see you have added multiple images to your form, there are some with a large size and indeed when checking the the content that loads in the form the images are the ones that are currently taking more time to load. 

Here's a screenshot that will show you want I can see on my end: 

I have also checked and there is an image with a size of 5 MB, it is taking more time to load, it is taking about 2.2 minutes to download on my end as shown in the screenshot above. 

When checking with another similar form, but with less images the form loads very quickly, it takes about 5-6 seconds to load completely on my end: 

I would suggest you to compress your images to decrease the time to load in the form, here is a tool that may help you: http://compressnow.com/ 

Please make the change on your end and let us know how it goes. 

That really makes sense to me. Maybe if you let me know the recommended size or weight of the images for Jotform would be very helpful as the resource you mentioned below.
Thank you!…you really helped me out!

What I would suggest you is to compress the images in a 80% of their sizes on the tool I provided above: http://compressnow.com/ 

The image quality will not be affected when reducing the size with that tool, I mean you will not see the image with some pixels on it, you will still see the image almost the same as you currently see your images.

I have also reduced the images size on a cloned form of yours, here is the link so you can see it: https://form.jotform.com/63076709932968 

Hope this helps.
