Bulk Image Resizer

Resizing one picture is easy. Resizing eighty of them — a holiday album, a batch of product shots, a folder of screenshots destined for a website — is the job that actually takes an afternoon, and it is the one most tools quietly refuse to do. This one caps the longest edge instead of asking for exact dimensions, and that difference matters. A folder of photos will not share an aspect ratio: some are landscape, some portrait, a few square. Forcing them all to 1200 by 800 would squash half of them. Bounding the longest edge gives every image the same scale while leaving its shape alone, which is what people mean when they say "make these smaller". Images already inside the bound are handed back untouched rather than re-encoded, because re-encoding something that needs no resizing only loses quality and sometimes makes the file bigger. The tool tells you how many it left alone. Everything happens on your own machine. The images never leave the browser, there is no upload, no queue and no account, and you can take the results one at a time or as a single ZIP.
