Photo dimensions & file-size quick reference

Dimensions are width × height in pixels. Suggested file sizes are compression targets, not platform limits.

Need another shape? Crop first, then resize and compress. Keep your original; do not sacrifice detail just to reach a suggested target. JPG is usually suitable for photos. Etsy does not preserve PNG transparency.

How to use this tool

1

Choose an image

Select a JPG, PNG or WebP file from your device. The file stays in your browser.

2

Set the options

Choose the values required for the destination where you will use the image.

3

Process and download

Check the result, then download the new copy to your device.

Cropping changes the frame

A crop removes pixels from the outer area of an image. The X value moves the crop from the left edge and Y moves it down from the top. Width and height control the size of the area that remains.

Crop before resizing when the source and destination have different shapes. This preserves the subject instead of stretching the entire image into a new aspect ratio.

Common uses

Better composition

Remove empty space or distractions so the main subject is easier to see.

Match a layout

Create a tighter image before resizing it for a card, profile, listing or document.

Remove borders

Cut away scanner margins, screenshots controls or unwanted frames.

Prepare thumbnails

Choose the meaningful area before making a small thumbnail.
