Start with a useful pixel target

A 1080-pixel square is loaded now. Choose another preset or edit either number, then decide how your photograph should meet that box.
The same photograph twice at the same size on screen, split by a vertical line: the four thousand by three thousand original on the left, the eight hundred by six hundred result on the right.4000 × 3000800 × 600

When the box and the picture disagree

The ratio is locked, so all three would give the same pixels. Unlock to choose.

Common targets

PNG has no quality dial. It keeps every pixel exactly.

No file open yet.

Behind the drop zone: one photograph at both sizes, drawn the same size on screen. The line down the middle is the clearest difference there is between them.

Presets are starting points, not export profiles. The fields, crop rule, anchor and format remain yours.

Choose the destination before the number

A familiar size is useful only when it belongs to the place the image is going. Start with the card, thumbnail, post, video frame or form slot that must receive the file; then use its pixel box here. Resizing to a fashionable number and resizing again later spends detail twice.

Fit, cover and stretch answer different questions

Fit asks how large the whole picture can be inside the box. Cover asks how much of the picture must be cropped to fill every pixel. Stretch ignores the source proportions. For photographs, fit and cover are the defensible choices; stretch belongs to diagrams and textures where geometry is not identity.

Use the anchor as a composition control

When Cover removes a strip, the nine-point anchor decides which strip. Put a face near the top and choose a top anchor; put a product to the right and choose right. The preview shows the exact retained rectangle before any pixels are written.

Questions about the presets

Does a preset crop my picture automatically?

Only when Cover is selected and the source ratio differs from the target. Fit keeps the whole image and may produce a smaller second dimension; Stretch forces both numbers and changes proportions.

Can I change the numbers after choosing a preset?

Yes. A preset only writes width and height into the same fields you can edit yourself. Nothing is locked and the ratio chain can be switched on or off.

Why are there several square presets?

Because a 1080-pixel post, a 640-pixel profile image and a 256-pixel icon have different delivery costs even though their shape is identical. Choose the final display class rather than resizing the same square repeatedly.
