常见问题

How much can I reduce the file size?

Typical results range from 40-80% size reduction depending on the image and quality setting. Photos compress better than graphics with sharp edges.

What quality setting should I use?

70% is a good default for web images. For high-quality prints, use 85-90%. For maximum compression (email attachments), try 50-60%.

Which output format is smallest?

WebP typically produces the smallest files, followed by JPEG. PNG is largest but preserves perfect quality and transparency.

Does compression affect image dimensions?

No. Compression only affects file size and visual quality — the image dimensions (width × height) remain unchanged.
