Reduce the weight of an image on photoshop 

To avoid weight problem images directly mostly recent pictures of devices outputs, so you can send them by mail or put them on the internet, you have to reduce their size.

By double-clicking on the tool lens, the image is displayed at 100%. The fact that it allows us the great edit and / or print in good quality but to send that is not useful and compelling.

To resize my image, I double-click on the tool hand that allows me to display it to the screen size that best suits me to send it over the Internet.

In this case; the image is 23% of its normal size so the idea is to reduce that percentage up.

Go to the "Image" menu and then "Image Size" or alt + ctrl + alt on PC or i + apple + i on Mac and a new window will open.

In the dimensions of my image I change the percentage of pixels by unfolding the tab. Be careful to maintain proportions. Also make sure that I'm "bicubic sharper" for a better reduction (see the bottom of the window in the folder menu). Then press OK.

The image is now 23% of its size. I double click on the magnifying glass or hand tool to display it full screen.

Go then to "File" then "Save for web and devices". Check "Convert to RGB". Set the quality of JPEG, around 80, that's good. Save, type the name and choose the destination.
