Can ShortPixel automatically resize new image uploads?
Yes, ShortPixel allows you to resize the images when uploading them. This means that you can upload an image of any size; ShortPixel Image Optimizer will take care of resizing it.
To do that, it's as simple as enabling a setting. You can find it going to Settings > ShortPixel > General > Resize large images
The resizing feature also works when you are bulk optimizing your images (Media > Bulk ShortPixel).
Note: This feature resizes only the full original images, not the thumbnails. Also, take into account that, even though it's uncommon, your hosting might limit the size of your uploads. Therefore, if you can't upload a big image, it will be better to check it with your hosting, as ShortPixel accepts any image size.
There are two resizing options in our plugin settings menu. Keep in mind that the original aspect ratio is preserved in both cases.
Resize images – Cover
The first resize option is the most popular. It takes the small side of an image and reduces it to make it equal or greater than the value set.
For example, if you set the resize dimensions at 1000x1200, an image of 2000x3000px will be resized to 1000x1500px, while an image of 3000x2000px will be resized to 1800x1200px.
Important: The resized image should not be smaller than your largest thumbnail. You could actually enter a smaller value, but then you won’t be able to regenerate your largest thumbnail, if ever required.
Resize images – Contain
The second resize option takes the largest side of the image and it makes it equal to the value you set. Sizes will be smaller or equal to the corresponding value.
For example, if you set the resize dimensions at 1000x1200, an image of 2000x3000px will be resized to 800x1200px, while an image of 3000x2000px will be resized to 1000x667px.
If you are not sure which option is better for your use case, please test it on a few images from your WordPress Media Library. Make sure to keep the Image backup option active, in case you are not pleased with the results.
