How do I make an image smaller without losing quality?

Use our Lanczos resampling filter when reducing dimensions. It preserves maximum detail and sharpness during downscaling, producing results nearly indistinguishable from the original.

What is the difference between making an image smaller and compressing it?

Making an image smaller reduces the pixel dimensions (e.g., 4000×3000 to 400×300). Compressing reduces file size by adjusting encoding quality without changing dimensions. You can use both for maximum file size reduction.

What size should I make my image for the web?

For most web uses, 800–1200 pixels on the longest side is ideal. For thumbnails, 300–400 pixels works well. The right size depends on how the image will be displayed.
