This wikiHow teaches you how to compress a photo to make it take up less space on your hard drive. Compressing photos is often necessary before sending them via email or uploading them to your website. You can compress photos on both Windows and Mac computers by using a free website, or you can use your computer's Photos app to compress an image to a smaller size. Keep in mind that there is no way to compress a photo while retaining the photo's original quality.
Steps
-
Open the Image Compressor website. Go to https://imagecompressor.com/ in your computer's web browser. This website allows you to compress up to 20 images in JPEG, PNG, and GIF formats at once. and you can control the level of compression on each photo. If you want to compress images in WebP, HEIC, and other formats, you can take a look at xconvert.com, ezgif.com, youcompress.com, and more. Check the supported image formats and file size limit first.

For example, if your banner is supposed to be 1200x600 pixels and you upload something with different dimensions, the template may automatically stretch or crop the image.
