Over a year ago I created this online web application Convert Hub by the help of the splendid open source image manipulation library Netpbm. Give it a try, upload an image and convert it to another format. But not just that, itâ€™s also capable of resizing an image, rotating or flipping it.
I love it. Itâ€™s simple yet adequately useful. The best part of it for a webmaster like me is that it can convert other image formats such as .bmp, .jpg, .gif and .png to .ico so I can use them as favicon.ico for my sites. Try these US state flags and convert them in any way you want!
Itâ€™s a great tool and gained tremendous popularity. I know this because one day DreamHost warned me of overwhelming server resource usage and took it down for good reasons. I had to move it elsewhere and Linode is where it currently resides on.
Server side computing is too expensive for a free application like this. After a few ideas and thoughts, I decided to create a client side software program to do the job instead. Itâ€™s called Batch Image Converter. And it proves to be much better. It doesnâ€™t come with a daily limit on the number of conversions allowed per IP but you can do as many conversions as you want. The whole software consists of one single executable file, thereâ€™s even no need to go through any installation steps. Itâ€™s totally green to your system. Whatâ€™s best, it can work in batches which means you are able to perform operations such as format conversion and dimension resizing on a lot of images by a single click.
All you need is to download it there. Itâ€™s free. The problem is that it only supports Windows for now. Iâ€™m planning on rolling out versions for other platforms but this may not happen soon.
Please do let me know what you think of the application in the forum.
