Jpeg (Joint Photographic Experts Group) is a commonly used method of compression for photographic images. It is designed to minimize the size of the picture. If you wish to reduce the size of an image you can either reduce its dimensions and/or increase the compression factor.

Windows Software - e.g. PaintRight click on your picture. Go to edit. There you will find options for resizing/dimensions your picture. It will tell you the current pixels as width x height. e.g. 2048 x 1536 pixels. You cannot change the compression factor.

Image Editors & ConvertersYou can easily achieve much better results if you use a tool that allows you to fine control the compression level and or other jpeg options. There are a lot of tools out there:
- freeware (for example Irfanview, Picasa, GIMP, ...)
- commercial tools (Photoshop, AZImage - see reference...).

Go to Image > Image Size. If you want to keep current Width and Height of the image uncheck Resample image then type new reolution in Resolution field. When you want to resample image (to change Width and Height to match new resolution) check Resample Image and type desired resolution in Resolution field.

Some of resolution of pictures on Google Street View is higher than other pictures. Some pictures feature resolution from five years ago, for example and that is already outdated. The exact maximum resolution of Google Street View is not disclosed.

This is an iPhone App that allows you to view pictures with such big resolution that they are on the giga-pixel scale. This allows you to seemlessly zoom in and out on pictures of immense size (which is actually an intrigueing experience). For example; you can start out with an aerial sattelite view of earth and zoom all the way in on your house because it's one big picture. QUITE intense.
