Pro Tips & Best Practices

1Maintain Aspect Ratio

Keep the aspect ratio locked to prevent image distortion. Only unlock when you specifically need to stretch or compress the image.

2Choose the Right Dimensions

Use preset sizes for social media platforms, or calculate custom dimensions based on your specific needs. Consider the final use case.

3Upscaling Considerations

Enlarging images beyond their original size may reduce quality. For best results, avoid upscaling by more than 150% of the original dimensions.

4File Format Impact

JPG is ideal for photos, PNG for graphics with transparency, and WEBP for web optimization. The format affects both quality and file size.

5Batch Processing Workflow

For multiple images with the same target size, note down the exact dimensions and apply them consistently to maintain uniformity.

6Quality Preservation

When downsizing, the image quality is generally preserved well. Always preview the result before downloading to ensure it meets your requirements.

提示： All resizing happens locally in your browser - your images never leave your device, ensuring complete privacy and security.
