Frequently Asked Questions
🌄 Original Images
What happens to my original images?
We only need read
access to your original image storage. We only fetch original images for processing them but we don't write or modify any image. You retain all your high-quality original images as it is under your control.
What access permissions do you require for our original images?
We only need access equivalent to read
. We must be able to fetch images from your original bucket or server. We won't need any write
access.
What is the price for fetching original images?
There is no charge for fetching original images from your image source.
I am storing my original images in Amazon S3. Will I get charged by Amazon each time you fetch the original image?
We always cache your original image in our local cache after fetching it for the first time. This means if your 1 MB image is resized 3 times, you will only be charged by Amazon S3 for 1 MB data transfer and 1 single request. Subsequent resize operation will be performed on the cached image.
Can I store my original images with Gumlet?
We don't support image storage. You can choose any file storage service like Amazon S3, Google Cloud Storage, DigitalOcean Spaces, or any other storage of your choice. This way, you also retain full control over your original images and won't have to suffer from vendor lockin.
What happens if my original image is modified?
We cache your original image for 3 months so we will still keep serving cached images. You need to clear cache through the dashboard or API to reflect the change in your original image.
What happens if my original image is deleted?
We cache your original image for a maximum of 3 months. If we need to revalidate the original image, it will start throwing a 404 error. If you flush the cache after deleting the original image, then we will start throwing a 404 error for that image.
Is there any limit on the input file?
We support an input image that is a maximum of 8192x8192 pixels.
What input image formats are supported?
You can find details about input image formats here: input formats
What happens when my original image is not found? Do my users see a broken image?
By default, we will return a 404 error when the image is not found and your users may see a broken image. You can configure a fallback image in your source settings. If that image is set, we will display that image instead of showing a broken image.
🌅 Output Images
How are processed images stored?
We store processed images in our cache. The processed images are also stored in the CDN cache. This ensures that if an image is already generated, no extra time is spent delivering them.
What is the maximum output image size?
We support a maximum output image size of 8192 x 8192 pixels.
What output formats are supported?
You can find details about output image formats here: output formats
Does Gumlet automatically remove EXIF metadata?
Yes, we remove all unnecessary EXIF metadata from processed images. Your original images however are untouched so all that metadata is always present there. If you want to keep the metadata from original images in output images as well, you can check this parameter: metadata
SEO
Can serving images from Gumlet CDN (or third-party CDN) be SEO-negative?
No, it will be actually beneficial. Your images are marked as originating from your website via HTTP headers sent by our system. Search engines look at that header and will associate those images with your website even if the URL is pointing to Gumlet.
We instruct search engines about the location of original images so they always attribute your image to your site rather than attributing it to our CDN. You can read more about that in this article and this Google documentation.
🗄 Caching
How long are my images cached?
We cache your original images for a maximum of 90 days and processed images for 100 days.
Is there any way to modify browser cache time?
Yes, we support modifying browser cache time. It's set at 100 days by default but you can change it in the cache management section of the source.
Is there any way to modify CDN cache time?
We generally don't recommend modifying CDN cache time but if you must do it, please contact our support and we will be able to guide you.
What is the default cache time for errors?
All errors are cached by our CDN for 5 minutes. That means, if an error comes, it will be served from cache for the same user from cache for 5 minutes before revalidating the resource again. If you are on an enterprise plan, you can contact support to modify the same.
🔗 Gumlet Integration
What is the impact of adding javascript on my page load time?
Our Javascript plugin is super lightweight with just 6 KB in size. It loads in less than 50 milliseconds via async
method. This ensures it never becomes a roadblock in page-load.
In short, you should not even notice any impact on page load time due to our plugin.
How to optimize images served via CSS background?
You need to remove the CSS background-image
property and you need to set data-bg
attribute with image URL. Our library will ensure correct-sized background image will be loaded. You can find more information about it here: set image as background
Does Gumlet handle lazy loading? Should I use a third-party library?
Gumlet library is able to handle lazy loading. We recommend that you remove any third-party library and rely on our library for lazy-loading. Check more about enabling lazy loading here: lazy load images
Can I serve images from multiple sources?
Yes. You can serve images from as many different sources as you want. You just need to create multiple sources in the Gumlet panel and configure the Gumlet.js to load different images from different domains. A detailed example is given here: load images from multiple domains
Can I serve CSS / JS / Other files through Gumlet?
Yes! You can serve all kinds of files from our service. If we detect non-image files, we will not process them but we will directly deliver them through our CDN. You get the advantage of fast delivery of those files and reduced latency.
How do you serve these files? Simple, you just serve them the same way you serve images. For example, if your CSS file is stored at https://example.com/css/main.css
you need to set up a web folder source with a Base URL of https://example.com
. After you set up the source, you can serve the CSS file like https://example.gumlet.com/css/main.css
It's that simple and your CSS file will now be delivered by our CDN.
💳 Payment
What currencies are supported?
We accept payments in USD. If you are paying from any other currency you will be charged as per the equivalent exchange rate.
Are my payment details secure?
Absolutely! We use https://www.stripe.com to store your payment information and process payments. None of your credit card details are received or stored on our servers.
When do you charge my credit cards?
We will send you an invoice on the 1st of every month. If you have a credit card saved, it will be charged on the same day.

We do support optimizing images on Magento. Please follow this simple guide to start serving optimized images.

Please follow our Gumlet.js (JavaScript plugin) integration. Getting started guide.
Webflow, Wix, Squarespace, and Weebly
We don't support optimizing images for the above platforms. We will keep these in our mind though and if there is huge demand, we will be publishing plugins when needed.
💵 Pricing
How is the bandwidth charge calculated?
We calculate bandwidth as the amount of data transferred from our CDN to your users. If your image bandwidth was 10 TB before you switched to Gumlet and it becomes 6 TB after the switch, you will only be charged for 6 TB by us.
There is no extra charge for a number of requests, a number of transformations, caching, or storage.
Why is the price is lower than the one displayed on the CloudFront website?
We have committed to using a contract with CloudFront which reduces per GB pricing of CloudFront for us. We serve more than 100 TB images in a month and hence enjoy lower per GB pricing. Rather than beefing our profit margins, we chose to pass it on to our customers.
We also provide the same price across the globe so you can enjoy a very predictable pricing structure.
