Resizing Images with Express

How to resize images using the free online tool Express by


This tutorial assumes you are familiar with the following:


Why Resize Images?

It's good idea to resize your images before uploading them for a few reasons:

  1. Large images make your pages load slowly, and nobody likes that.
  2. Most images above 500 pixels (px) wide will be cut off for many of our users.
  3. The CommonSpot image editor is slow and clunky.

Why Use Express?

There are many ways to resize images on a computer, but not everyone in the City has the same software, or the same permissions for installing software, on their machines.

This means that we have to find something that's free and accessible to everyone. As far as we know every contributor has a web browser with Flash installed on it.

Express is fast, relatively easy to use, and doesn't require that you create an account.

What Size Should They Be?

This depends on the layout you are using. Remember that the website resizes based on browser size, so maximum-width images might be cut off for some users.
