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.

Highly recommended. + Seems tightly coded - just working - no messing; + The price point is the best in the market for on the fly image optimisation & CDN from what I can tell. + Excellent functionality afforded by the lightweight PLUGIN to compress/optimise all your images (same not available even at source using Imgix); + Uses Cloudfront CDN - you know what u r getting; and + Plays nice with S3 & Elementor. - We are looking forward keenly to the option to purchase custom CNAME configurations for our subsites. It is not a possibility for us to use an S3 CNAME due to the HTTP. It causes cache issues and we lose the WordPress admin bar. WIll gladly purchase custom CNAMES across our multisite networ; - The Elementor additional setting could do with a bit more attention. Putting instructions for elementor in the plugin itself would be a nice touch.

Si vous recherchez à accélérer votre site, je vous conseille de tester ce plugin. Ils ont un très bon soutien très réactif. Un point à faire attention, mais ce n'est pas de la faute du plugin bien désactiver LazyLoad sur le thème comme, par exemple Divi ou il peut être actif ou dans les autres plugin comme wp-rocket pour ne pas avoir de problème. Et en plus maintenant, il est pris en charge avec Brizy.

I got this for a different project outside wordpress, but than used it on every customer we build websites for. If you run your website through the google insights tester you will realize why you need this plugin. Trust me search on google for google insights and check your website, if you get under 90%, you need a lot of help. Well if you get next gen images error, this plugin will fix it. The support is amazing, I have never had to wait more than a few minutes to get a response. While I honestly hate wordpress some of our customers like it, and I am happy to see that they made a module to make this simpler. Also in comparison to cloudenary they are on tenth of the price, we use to pay 50$ a month now we pay less than 4$ and we server thousands of images per day.

This plugin does exactly as advertised. There were a couple of gotchas when I first started using it but a quick online chat to support got it working as expected. Their service works great with wordpress and the CDN is fast. Highly recommended.
