Pro Tips for Maximum Image Optimization
Getting the smallest file size requires the right approach. Keep these tips in mind:
- Check Dimensions First: If your image is 4000x4000 pixels but will only be displayed at 500x500 pixels, use our Image Resizer *before* compressing to save massive amounts of data.
- Choose the Right Format: For photographs, JPG or WEBP will compress much better than PNG. If you don't need a transparent background, consider converting to WEBP.
- Test Quality Levels: Start with an 80% quality setting. It often cuts file size in half while remaining indistinguishable from the original to the human eye.
