Uploading images are often a stumbling block: aspect ratio, dpi, size,etc can be confusing and lead to undesired results…
“TinyJPG reduces the file size of your JPEG images. Every uploaded image is analyzed to apply the best possible JPEG encoding. Based on the content of your image an optimal strategy is chosen. The result is a quality image without wasting storage or bandwidth!”
Might be worth a go next time you have to upload a big image file?
As explained by Ben in another post Images in Archived folders , we now have Focus X, Focus Y settings to give you some control over the cropping of large images.
