Resizing Images Using Pixlr

Artists often need to resize images in order to enter an exhibition or to prepare for printing.  An exhibition may require a specific size, such as “1200 pixels on the longest side”.

There are many tools available to resize images.  Here we’ll use Pixlr, a free web-based tool which can be used from a Windows PC or a Mac.

Pixlr makes several image tools available.  For these instructions, we’ll use Pixlr E, Pixlr’s free photo editor.  Without an account, Pixlr E allows 3 file saves per day.  Signing up for a free account may allow more saves per day.

To resize an image using Pixlr E:

  • Open Pixlr E by going to using any Web browser.
  • Drag the image file you want to resize onto the Pixlr E web page.  This will open the file.
    — Or — 
    Click the button “Open Image”, navigate to the file you want to resize, select it and click “Upload”.
  • A window titled “Pre-resize image” may appear.  If this window does not appear, no worries, all is well. If it does appear,
    • Ensure that the “switch” labeled “Auto rotate based on exif” is “off”.  The “switch” should be dark and to the left.
    • Click on “Full HD”, then click on “Apply”.
  • A window will appear, showing the image in a window with a lot of controls.
  • From the menu at the top, select “Page” and then “Smart Resize”.
  • A window titled “Smart resize” will appear.  Ensure that “Lock proportions” is selected (colored and to the right), “Scale” is selected (colored), and “Smoothing” is selected (colored and to the right).
  • Determine whether “Width” or “Height” is the larger number.  For whichever is larger, type “1200” into that box, replacing the previous number.  The other dimension will automatically adjust to scale.
  • Click “Apply” in the lower right corner of the window.  The window will close.
  • Click the colored “download” button in the lower right corner of the window.
  • A window titled “Save” will appear.
    • In the box under “Name”, type in the filename you’d like to use for the file.  For a WSO exhibition, the filename would be of the format “SmithJane-BluebirdInATree”.
    • Select “JPG” and then “High quality”, then click the “Save” button.

That’s it, you’re done! On a Mac, the resized image has been saved to your “Downloads” folder.
