How to compress image size?

[sspbond007]

Hi,

Is there any way to compress image size in iphone? Actually my application is uploding images to server from phone. It takes long time to upload the original image. So if I can compress or convert to thumbnail, it'll help me out.

thanks

You could convert the image to jpeg using UIImageJPEGRepresentation() and a compression quality.

Alternatively you could convert it to png and use a tool like optipng (http://optipng.sourceforge.net/) to try and compress it further.
