Drop the advertiser's high-res files. Pick the ad size for each file (the tool suggests one by shape and warns you when a file isn't a good fit). It's cropped to the exact ratio, downsampled with Lanczos-3, then compressed under your file-size cap. Runs entirely in your browser; nothing is uploaded.
