Tips & Best Practices
Keep the original proportions to avoid distorted images. Use crop or padding if exact dimensions are required.
Balance file size and image quality - use 80-90% quality for web images, higher for print materials.
Resize based on intended use - smaller for web thumbnails, larger for hero images or print materials.
Resize multiple images with the same settings to save time and ensure consistency across your project.
Create multiple sizes for responsive web design: mobile, tablet, and desktop versions.
Keep EXIF data for photography portfolios but remove it for web optimization and privacy.
JPEG for photos, PNG for images with transparency, WebP for modern web optimization.
Verify resized images display correctly on intended platforms and devices before publishing.

Frequently Asked Questions
Will resizing reduce my image quality?
Resizing down typically maintains good quality, especially with modern algorithms. Resizing up may reduce sharpness. Use appropriate quality settings and avoid extreme size changes for best results.
What's the difference between resizing and compressing?
Resizing changes image dimensions (pixels), while compressing reduces file size by adjusting quality. Both can reduce file size, but resizing changes the actual image size.
Should I maintain aspect ratio when resizing?
Yes, maintaining aspect ratio prevents distortion. If you need exact dimensions, consider cropping or adding padding rather than stretching the image.
What image sizes should I use for different social media platforms?
Instagram posts: 1080x1080, Facebook posts: 1200x630, Twitter headers: 1500x500, LinkedIn banners: 1584x396. Platform requirements change, so check current specifications.
