Worth knowing

How to get this right.

01

Never scale an image up
Enlarging invents pixels that were never captured, and every method for doing it produces either softness or crunch. If you need a 2000px image, go back to the original file. If there is no larger original, the honest answer is that the image cannot be used at that size.
02

Match the size to the slot, then double it
A hero image in a 1200px container needs a 2400px file to look sharp on a high-density screen — and nothing beyond that. Anything larger is bytes your visitors pay for and cannot see.
03

Resize before compressing
Dimensions dominate file size far more than quality settings do. Halving the width of an image quarters its pixel count, which typically beats anything the quality slider can achieve.

Questions

About this tool.

Does resizing reduce quality?

Scaling down is essentially lossless to the eye — you are discarding detail that was too fine to display anyway. Scaling up always loses quality, whatever tool you use.

What format does it save as?

PNG, so the resize itself adds no compression artefacts. Run it through the compressor afterwards if you want a smaller file.

Can I crop rather than squash?

Not yet — this tool scales to the exact dimensions you give it. Keep the ratio locked and it will never distort; unlock it only when you deliberately want to stretch.

Is there a maximum size?

Ten thousand pixels on either side. Beyond that, browsers start refusing to allocate the canvas.
