为什么我的 JPG 保存后变模糊?

Why does my JPG look blurry?JPG uses lossy compression that discards image data each time you save. At low quality settings (below 60%), visible blurring and artifacts appear, especially around edges and fine details.

How do I save JPG without quality loss?Save JPG at 85-100% quality in your image editor. Avoid saving the same JPG multiple times as quality degrades with each save.

Should I use PNG instead of JPG to avoid blurring?PNG is lossless and does not degrade, but files are larger. Use PNG for graphics and screenshots. Use JPG at high quality (85%+) for photographs.

What JPG quality setting should I use?Use 85% for web images (good balance of quality and file size). Use 95-100% for images you plan to edit further. Use 100% only when maximum quality is essential.

Can I recover quality from a blurry JPG?No, JPG compression permanently discards image data. The original quality cannot be recovered once lost. Always keep original high-quality files.
