Why resize images?
Resizing images can help improve performance, compatibility and usability. Large images can slow down websites, take longer to upload, use more storage and be harder to send by email or messaging apps.
A properly resized image is easier to upload, faster to load and better suited for its final use. For websites, smaller dimensions can help pages load faster. For documents and presentations, resizing can make files easier to manage. For social media, resizing can help images fit better into the required layout.
