Tips for Optimal Image Compression
To get the best results from our Image Compressor, consider these useful tips:
- Start with a Reasonable Target: Aim for a target size that is achievable. Extremely small targets for large images might lead to very low quality.
- Consider Original Image Size: If your original image is already very small (e.g., 50KB) and your target is 100KB, the tool will simply provide the original image as it's already within the target.
- Image Dimensions Matter: While this tool focuses on file size, remember that larger image dimensions inherently lead to larger file sizes. If your image is excessively large (e.g., 4000px wide) and only needed at a smaller display size (e.g., 800px), consider resizing it first using a dedicated tool for better results.
- Preview is Key: Always review the compressed image preview to ensure the quality meets your expectations before downloading. If the quality is too low, try increasing your target file size.
- Supported Formats: This tool works best with JPG, PNG, and WebP images. For JPG and WebP, quality adjustment is very effective. PNG compression is lossless, so achieving a very small target size might be harder if the original PNG is complex.
By following these tips, you can achieve optimal image compression for faster loading times, reduced storage, and improved overall performance.
