How to Fix a Blurry Image After Compression
Sometimes an image becomes blurry when you try to reduce it to a very small file size.
Here are some ways to improve the result:
- Reduce dimensions carefully: Avoid making the image unnecessarily small.
- Adjust quality gradually: Don't immediately select the lowest quality setting.
- Choose the right format: JPEG or WebP can work well for photographs, while PNG or lossless WebP may be better for screenshots and graphics.
- Start with the original image: Avoid repeatedly compressing an already compressed image.
- Check readability: Make sure faces, text and important details remain visible.
According to MDN's image format guide, different image formats offer different compression and quality characteristics.
