Have you ever uploaded a photo only to find it looks stretched, blurry, or oddly cropped? The issue is usually image dimensions. Learning how to resize an image correctly is a must-have skill for bloggers, designers, and anyone managing digital content.
But resizing isn’t just about pixels—it’s also about file size limits. Many platforms require images under a specific KB size. This guide will show you how to master both with the free OpusTools Image Resizer.
Resizing vs. Compressing: What’s the Difference?
People often confuse resizing with compressing, but they are very different:
- Resizing → Changes the dimensions (width/height in pixels). Example: resizing a 2000px-wide photo down to 800px.
- Compressing → Reduces the file size (in KB) without altering dimensions, usually by adjusting quality.
👉 For best results, resize first, then compress. Smaller dimensions reduce file size naturally, and compression fine-tunes it to your target.
Use the OpusTools Image Resizer for dimensions, then the OpusTools Image Compressor if you need extra file size reduction.
