How much can I compress an image?

Typically 60–90% file size reduction is achievable for photos. The exact amount depends on image content and your chosen quality setting.

What is the difference between lossy and lossless compression?

Lossy compression (JPG, WEBP, AVIF) removes some image data to achieve smaller files. Lossless (PNG) compresses without removing data, resulting in larger files but perfect quality.

Will compression affect my image dimensions?

No. Compression only reduces file size. The pixel dimensions remain unchanged unless you also use the resize tool.

What quality setting should I use?

For web images: 75–85%. For print: 90–95%. For archival: use PNG lossless compression.
