Image resize without Imagick and losing transparency

Is there a way, to resize images with formats: GIF, PNG, JP(E)G, without installing additional classes like Imagick?

The most important thing is that images can't lose their transparency (PNG, GIF) and also in case if it's animated, resize it, but without losing GIF animation.

php has an extension called GD that should be installed

GD Extension Reference

that you can use. On the page above are a bunch of examples to do exactly what you want to do. I personally haven't used it for animated GIF images, but have for the other image formats. One thing though is that JPEG images use A LOT of RAM with this library because the library decompresses the JPEG image into its byte format - essentially making it the equivalent of a 16.7 Million color Bitmap.

To see if the extension is loaded you can call the extension_loaded('GD') function and it will return TRUE if it is. Or you can type at the command-line php -m and see all the extensions there. php -m | grep -i gd should do it.

Just to be clear, the GD library is not very efficent so reconsider using the Imagick extension.

EDIT: Resize image sample using GD Extension
