Whether you need to scale images for web use, reduce file size for email, or enlarge photos for printing, our tool handles it all.

Perfect for web developers, designers, photographers, and anyone needing quick image resizing. No software installation required—works entirely in your browser with complete privacy.

Enter precise width and height in pixels. Perfect for web images that must fit specific layouts or requirements.
Scale images by percentage (e.g., 50% to halve size, 200% to double). Simple and intuitive resizing method.
Lock aspect ratio to prevent distortion. Change one dimension and the other adjusts automatically for proportional sizing.

All resizing happens locally in your browser. Your images never uploaded to our servers. Complete privacy.
Reduce image dimensions for faster page loading. Typical web images: 1920px wide for full-width, 800-1200px for content images.
Shrink images to fit email size limits. Resize to 50-75% of original to reduce file size while maintaining quality.
Resize for optimal social media display. Instagram: 1080x1080 (square), 1080x1350 (portrait). Facebook: 1200x630 for link previews.
Enlarge or resize images for specific print sizes. Maintain 300 DPI for quality prints: 4x6" needs 1200x1800px.
Resize profile photos to platform requirements. LinkedIn: 400x400px, Twitter: 400x400px, Discord: 128x128px minimum.
Create smaller versions for thumbnails and previews. Typical thumbnails: 150x150px to 300x300px for grid displays.
Begin with the largest version. Scaling down preserves quality better than scaling up.
Web: 1200-1920px wide. Email: 600-800px. Social: platform-specific.
Unless you specifically need stretching, keep aspect ratio locked to avoid distortion.
For web, use 2x your display size (800px display = 1600px image) for sharp retina rendering.
Smaller dimensions = smaller file size. Balance quality with loading speed.

Resizing down (making smaller) preserves quality well. Enlarging (making bigger) may reduce sharpness. Our algorithm minimizes quality loss.
