Resize your photos and images

Attention!: always save the resized image with a different filename, or in a different folder, not to overwrite the original.

1. Online sites: If you are in a hurry and dont have a software available you can use an online site, as the Resize 2 mail one. Free to use and with an easy interface, it resizes and/or crops your image, and you can then save it again on your computer to use it.
2. Paint: If you don't have access to graphics editing software nor to the internet you can use Microsoft Paint to resize images as follows:
   • Right click on the file name, to Open it in Paint
   • On the Image menu, click Stretch/Skew.
   • Change the Horizontal and Vertical values for stretch to the desired percentages. They must be the same if you want the image to remain proportional.
   • Click Ok and then use the command File, Save As, to save the resized image with a different name.
3. Picasa: Google's Picasa can be used for simple image editing. Photos can be resized using the Export command, in the bottom toolbar.
   • You can multiselect any number of photos by clicking on them keeping the Cntrl key pressed,
   • Provide a name for the folder containg the resized photos, as the original will not be overwritten.
   • Define the horizontal size of the new photos.
   • Click OK
4. Photoshop: You can resize the images in many different ways. To reduce the file size  you have to reduce the number of pixels as follows:
   • Use the menu Image, Image Size
   • Enter the horizontal size in pixels (or percent); the vertical one will be automatically scaled.
   • Verify that Resample is checked
   • Click Ok and then use the command File, Save As, to save the resized image with a different name. Remember to change the file Format to JPEG, otherwise the file will be saved in .psd format (Photoshop)
   • Alternatively you can use the command File, Save for Web, where you can at the same time resize and define the compression factor.
