Question: How do I resize an image before uploading it?
Large image files, such as high-resolution photos, are too wide to fit in a column on your web page. School Loop can scale them to fit the page, but your web pages will load more slowly, with no benefit. To avoid this problem, it's smart to resize large images before uploading them to your website.
Below are three ways to change the size of an image, for example to scale it down to a width of 400 or 700.
A. Scaling an image on a Macintosh
- Open the image in the Preview program.
- Select menu choice Tools -> Adjust Size....
- Make sure that Scale proportionally is checked.
- Change the number in the Width box. The height will change to match.
- Save the file.
- Close the image window or Quit from Preview.
B. Scaling an image on a PC
- Open the image in the Microsoft Paint utility program.
- Click Resize in the menu bar.
- Make sure that Maintain aspect ratio is checked.
- Pick the Pixels radio button (as opposed to Percentage).
- Change the width number in the Horizontal box. The height number in the Vertical box will change to match.
- Save the file.
- Close the image window or Exit from Microsoft Paint.
C. Scaling an image using the Internet
- Go to resizeimage.net.
- Click the Upload and image button and navigate to your image file.
- Wait until the image uploads and displays.
- Scoll down to the Resize your image section.
- Make sure that Keep Aspect Ratio is checked.
- Three numbers are shown: a percentage, the width, and the height. Change the width number in the middle box. The percentage and height will change to match.
- Scroll down and click the Resize image button. A new section will appear showing the before and after sizes.
- Click the Download image link. The new file will download.
- Find the downloaded file in your downloads folder. It will have a name like Webp.net-resizeimage.jpg, which you can rename.
Note: There are other websites that resize images. If this one doesn't work, search for "resize image tool" and pick another one.
