Nowadays, many jobs need to use photoshop very well, photoshop mainly deals with digital images composed of pixels. With its many editing and drawing tools, image editing can be carried out effectively. PS has many functions, including image, graphics, text, video, publishing and so on.

Photoshop can satisfy many ideas, much more than Gimp’s image function. Because my sense of use is , as an image editing software ,Gimp is good ,but it lacks systematic color management, and compare with photoshop, it is more selections to users , and easier to use.

Prepare image for web, website content should have a lot of part to make up, including text ,video, and image. Many types of images have different pixels ,maybe low or high, but one thing is important is the picture need to meet most electronic produces and networks. And we can use photoshop to implement it.

And three photos above, the original image have 109k, maybe it is enough small , but i can use photoshop to make it lower in pixels, i could change the color quality and try lowering the JPEG quality to apply more compression and lower the file size , and you can see we get a 40.08k image. And i just save it.

Finally ,we can see how to choose the best file format for an image, and how to tweak the settings to get file size as small as possible while still retaining as much image quality as possible.
