Chrome Web Store listing

Crop a Chrome Web Store promo tile to exactly 440x280

The small promo tile is the required image the Chrome Web Store puts next to an extension in listings, and it has one size: 440 x 280 pixels, as PNG or JPEG. It is small, which decides what belongs on it: a mark and a few words rather than a screenshot. The editor above is fixed at 440x280 and exports PNG, which holds flat colour and lettering together at that size. Load the artwork, place it behind the frame, read the exact file size, and download. Nothing is uploaded.

How to make the 440x280 promo tile

Steps

Fit the mark, not the whole picture

440x280 is about the size of a business card on screen. A full illustration scaled down into it turns into texture, so crop to the logo and at most a few words of type.

  • The frame is fixed at 440 wide and 280 tall and does not move.
  • Scale the artwork down until the mark sits comfortably inside the frame, then position it.
  • Fine print does not survive at this size; keep the wording to a few words.

Decide what happens to the background

Cropy carries source transparency into the PNG, and any part of the frame the artwork does not cover stays transparent instead of being filled with a colour. If the tile has to be solid, bring artwork that is solid to its edges, or export JPEG, which has no alpha channel at all.

  • PNG and WebP keep the alpha of the source; JPEG cannot carry it.
  • The preview shows a checkerboard wherever the exported pixels will be transparent.
  • The store accepts both PNG and JPEG for this tile.

Check the file before uploading it

The footer shows the output dimensions and the exact size of the file the current settings produce. The store states no weight limit for the tile, and a 440x280 image is small either way; the number is there so the upload is not a guess.

  • The output line must read 440x280 before you download.
  • PNG has no quality setting; switching the format to JPEG brings out the quality slider.
  • Encoding happens in this browser, so the number matches the file you get.
