inktober 2017 day 9

I’ve been getting my inktober images into the blog with my iPhone camera.

My iPhone takes a picture that’s about 2.3Mb in size, and 4032×3024 pixels.

The screen on my iPhone however is only 1334×750 pixels so the image is much bigger than the screen, which is great as it allows images to be cropped without losing quality. However a 2.3Mb image will download slowly and use up a fair bit of bandwidth so If you are sharing images on the web it makes sense to keep them to a reasonable size.

A reasonable size for images most web pages is about 1000 pixels wide, and about 150-200Kb.

So how do you make the file smaller. Some services will do this automatically, Instagram for example reduces uploads to 1000x1000pixels. But if you want to reduce the size of an image it’s super easy.

On a mac you just double click the image to open it in Preview.

Select Tools>Adjust Size, and then set it to somewhere around 1000 pixels width. With the scale proportionally selected the image with keep the original aspect ratio.

Once done Export, and add a little compression, around 60% is a good starting point.
