Tumblr Image Resize Trick

You can get five sizes of the same image by simply modifying its URL once its uploaded to Tumblr. This seems to work on all published Tumblr images. Cool.

For this example we start with the URL:

“http://24.media.tumblr.com/af9f6d0f2485a9ca7844874851719541/tumblr_mrlcxiWXY81spe5sjo1_1280.jpg”

The trick is to change the text after the underscore. We start with “1280”.

Remember, a simple right click on the image allows multiple options to work with the image in most browsers



This uses “1280” but is scaled to fit into largest available width for your theme.



Changed to “500”.



Changed to “400”.



Changed to “250”.



Changed to “75sq”.

Notice this was automatically cropped for a different aspect ratio.

Of course, you can use these image URLs to include the images in other Tumblr posts, non-Tumblr web pages, or documents too.
