Wanneer pas je het formaat van afbeeldingen aan
Website Optimization
Reduce image dimensions for faster page loading. Typical web images: 1920px wide for full-width, 800-1200px for content images.
Email Attachments
Shrink images to fit email size limits. Resize to 50-75% of original to reduce file size while maintaining quality.
Social Media Upload

Print Preparation
Enlarge or resize images for specific print sizes. Maintain 300 DPI for quality prints: 4x6" needs 1200x1800px.
Profile Pictures
Resize profile photos to platform requirements. LinkedIn: 400x400px, Twitter: 400x400px, Discord: 128x128px minimum.
Thumbnail Creation
Create smaller versions for thumbnails and previews. Typical thumbnails: 150x150px to 300x300px for grid displays.
Pro tips voor het aanpassen van afbeeldingsformaten
Start with High Resolution
Begin with the largest version. Scaling down preserves quality better than scaling up.
Know Your Target Dimensions
Web: 1200-1920px wide. Email: 600-800px. Social: platform-specific.
Always Maintain Aspect Ratio
Unless you specifically need stretching, keep aspect ratio locked to avoid distortion.
Consider Retina Displays
For web, use 2x your display size (800px display = 1600px image) for sharp retina rendering.
Check File Size After Resizing
Smaller dimensions = smaller file size. Balance quality with loading speed.
