As answered by people managing QuokkaPix and Opalstack.
QuokkaPix's answer
Pipeline scenarios — you can chain multiple tools (resize → compress → convert → watermark) into one automated workflow and apply it to dozens of files at once. Everything runs locally in your browser, no files ever leave your device.
QuokkaPix's answer
Most image tools do one thing. QuokkaPix does everything in one place — resize, crop, rotate, compress, convert, watermark, rename, apply effects — with batch processing and pipeline scenarios. No registration, no uploads, no watermarks, completely free.
