How to Resize an Image Without Losing Quality
Resizing an image correctly preserves its sharpness and colour accuracy. The key is to use high-quality smoothing algorithms and to compress after resizing — not before.
Step-by-Step Instructions
1
Upload your image
Open the Pixaroid Image Resizer and upload your image. The tool shows the original dimensions.
2
Enter the target dimensions
Enter the width and height in pixels. Enable "Lock aspect ratio" to prevent distortion.
3
Choose the fit mode
Contain fits the whole image inside the frame. Cover crops to fill. Stretch forces exact dimensions without cropping.
4
Select output quality and format
Use JPEG at 92% for photos, PNG for graphics, or WebP for the best web performance.
💡 Pro Tips
- Always resize before compressing — never compress then resize.
- Use "Contain" for product photos and "Cover" for social media profile images.
- For AI-powered upscaling that adds real detail, use the AI Upscaler tool.
