Ten Tools for Cropping, Resizing, and Enhancing Images Online

This afternoon as I worked through a backlog of email I replied to a couple of questions about resizing images to make them fit under the size limitation for images in the new Socrative image-based question feature. I have tried a lot of image resizing, cropping, and enhancing tools over the years. Here are ten good ones to try.

Pixlr is a great set of image creation and editing tools. Pixlr offers web-based image editing tools as well as image editing tools to use on Android phones and on iPhones. Pixlr also has Firefox and Chrome browser extensions for creating screen captures.Pixlr Editor is Pixlr's most full-featured image creation and editing tool. You can create drawings from scratch using the pencil and coloring tools that they provide. Pixlr Editor also has options for uploading images or importing images from other places on the web. The selection of creation and editing tools is huge. There are options for making multiple layer images, dozens of filter settings, and of course tools for cropping and resizing images. Your images can be saved to your computer or you can send them to Flickr, Picassa, Facebook, or you can save them in a Pixlr account.

PicMonkey is one of my favorite online image editing tools. To get started using PicMonkey you can upload an image by simply dragging it from your desktop to the PicMonkey editor. From there you can change things like saturation, contrast, size, and sharpness. You can then add custom frames and special effects like "Polaroid style" to your images. Want to add text to your images? PicMonkey provides a slew of font styles for your use. And if you have just one tiny part of an image that you want to enhance or obscure, PicMonkey gives you tools for that too.
