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.
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.
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.
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.
We support an input image that is a maximum of 8192x8192 pixels.
You can find details about input image formats here: input formats
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.
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.
We support a maximum output image size of 8192 x 8192 pixels.

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
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.
We cache your original images for a maximum of 90 days and processed images for 100 days.
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.
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.
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.

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.
