I am a very basic user, doing simple, repetitive tasks, which typically involve cropping an image to a rectangular aspect ratio of 1.308:1 but to different pixel sizes. The online service the pictures are intended for has a maximum file size of 187kb per image, so I then scale my images, which are of different file sizes (so I can't use a default percentage scale), possibly 2 or 3 times until it is just under 187kb.
Is there an easier way to scale my cropped image to a fixed file size?
Many thanks,
Jules.
An easier way ? I do not think so, You can get a file size estimate in Gimp but only for jpeg exports.
In the jpeg export dialogue
Set the sub-sampling to 4:2:2 - that gives smaller file sizes
Enable the show preview option and above that is a file size estimate that changes with the compression setting.
Depends on end use, but I would say, if the required compression value comes out below 70 then cancel the export / resize and try again.
