Häufig Gestellte Fragen

How much can I compress without losing quality?

For JPEG: 75-85% quality is visually lossless for most photos. For PNG: lossless compression reduces size by 10-30%. For WebP: 80% quality gives excellent results. The human eye can't distinguish differences above 85% quality.

Does compression affect image dimensions?

No — compression only reduces file size, not pixel dimensions. Your image keeps the same width and height. For dimension changes, use our Image Resize tool.
