What it does
RedKetchup is a browser image utility suite with batch resize, compression, conversion, GIF editing and Windows icon or favicon tools.
RedKetchup’s bulk resizer accepts files, folders and unencrypted ZIP archives. Choose the resize rule and export format, process the batch, inspect the previews and download the results together as a ZIP. The practical limit is the browser’s memory: its help says the ZIP download can need three to four times the images’ combined size in RAM. The site says image files are processed locally and are not transferred to its servers, but its policy allows anonymous file metadata for statistics. The icon editor also stores its workspace and images in the browser’s IndexedDB, so local processing does not mean nothing is retained. Basic tools are free, with an optional ad-free upgrade.
