This is an install and forget about it plugin. As soon as the plugin is installed all of the images on your site will be optimized. Gumlet does not touch your original images, they remain as it is. Our JavaScript detects the user device screen size and optimizes each image on the page in real time without any delay. All of this is done automatically, no manual settings required.

Q: How many images can I optimize for free?

A: We have no cap on number of images that can be optimized through our plugin. You will be charged when your image delivery bandwidth exceeds 1 GB in a given month.

Q: How can I remove the 1 GB limit?

A: The limit is not hard enforced. When you cross the limit, we will send you invoice at the start of next month. Please pay it in 20 days and enjoy uninterrupted image delivery experience.

Q: Does Gumlet delete or replace my original full-size images?

A: Nope. Your original images always remain as they are and we never touch them. We only resize and compress images on-the-fly and cache it in our servers. You retain full control over your original images and they are never overwritten.

Q: I’m a photographer, can I keep all my EXIF data?

A: Yes! EXIF data stores camera settings, focal length, date, time and location information in image files. Since we never overwrite your original images, your all EXIF data will always be preserved. We only remove the EXIF data when we deliver images to your users.

At the very first after installing plugin my site got broke. Contacted support team (chat), they created a ticket and got revert after 7 days, but till that time I already found the what was the issue. No doubt AWS Cloudfront CDN is awesome at an affordable price, but support is not as good as CDN service 🙁

After I activate the WordPress plugin it creates some problems. It prevented showing most of the icons in one of my websites and a section of another of my websites. I have contacted them, they replied 10 hours later with the answer “Assigning to the tech team.” One day passed there was no answer, I contacted them again, still no answer. They’re extremely unresponsive, terrible experience! Additionally, when Gumlet Wordpress plugins is active Divi Theme Builder is not working, you cannot edit your theme properly.
