The image resizer requires the Microsoft® Silverlight® browser plug-in.




Silverlight is a browser plug-in similar to Adobe® Flash®.


Silverlight opens up new possibilities for great web based applications.


We also like and chose Silverlight because we think it has
better concepts for security and privacy settings than Flash®.

The 1-2-3 Image Resizer


The 1-2-3 Image Resizer is optimized for speed. Click "Open Image", select an image and click "Save Image" for a resized image you can send by email or upload to a server.


Why resize?


Pictures from a digital camera or mobile phone usually have a big file size. This is good for the image quality but also a disadvantage if you need to send an image over the internet. Even on modern internet connections you could be waiting five minutes if you try sending an image in its original (file) size.

Furthermore, not reducing the file size of an image for email communication means to put unnecessary strain on email servers/accounts. Especially on email accounts with limited storage size.


How to resize?


The file size of an image mainly depends on two properties. The image's resolution, i.e. the width in pixels times the height in pixels, and the grade of quality which depends on the grade of image data compression.


You can reduce an image's resolution in two ways. For one by scaling the image. Scaling means to alter the resolution of an image while keeping the contents of the captured scene but at less detail. So, for example, you could scale down an image from 3648x2736 pixels to 800x600 pixels which would reduce the file size by about 20 times.


Secondly, you can reduce the resolution by cropping the image. Cropping means to discard unnecessary parts of an image by cutting out the area of the image you want to keep. This approach doesn't reduce image detail. So, for example, if you cut out an area about four times smaller than the original image you would also reduce the file size by about four times.

Of course, you can combine the two means of reducing an image's resolution.


To speed up the process of resizing your image the 1-2-3 Image Resizer uses preset values for the grade of image data compression.
