WHY RESOLUTION MATTERS
Why Image Resolution Matters
Checking image resolution before using images for web, print, design, or sharing helps you choose suitable image dimensions and avoid quality problems such as visible pixelation.
Web & Social Media
Check image resolution before publishing images on websites, social media platforms, and other digital channels.
Print Materials
Higher pixel dimensions provide more image data for print workflows, although print quality also depends on physical print size and PPI/DPI.
Design & Publishing
Check resolution before resizing, cropping, placing or combining images in design layouts, presentations and publications.
Storage & Sharing
Higher-resolution images usually contain more pixels and may require more storage, depending on image format and compression.
