eBay Listing image size guide
The recommended ebay listing size is 1600×1600 pixels, an aspect ratio of 1:1. At 300 DPI that is roughly 135 × 135 mm when printed. Uploading at the exact size keeps text crisp, avoids the platform's own lossy re-compression and prevents awkward automatic cropping of faces or logos.
This page applies that preset automatically the moment you drop an image in. The complete image fills the required width and height without cropping or empty bands. Open the manual adjustments to choose Fit instead, change the background colour or output format between JPG, PNG and WebP, or lower the quality to hit a smaller file size.
