Why Resize Images?
High-resolution images look great but take up space and slow down websites. Resizing changes the actual pixel dimensions of an image, making it lighter and better suited for the web, emails, or specific display requirements.
Common Scenarios
Reduce File Size
Shrink massive 4K photos to 1080p or 720p for faster uploads and loading times.
Email & Forms
Meet strict attachment limits (e.g., <2MB) or profile picture dimension requirements.
