Resizing FAQ
Does resizing reduce image quality?
Downscaling usually preserves clarity; upscaling can soften detail. FotoLince uses high-quality interpolation to minimize softness.
Difference between resize and crop?
Resize changes overall dimensions proportionally; crop removes parts of the image. Use maintain-aspect to avoid distortion.
What dimensions should I target for web?
Hero/banner: 1600–2000px wide; product: 800–1200px; thumbnails: 300–400px; logos: 200–500px.
