- Upload one or more JPG/PNG/WebP images (drag-and-drop or browse).
- Set new width/height (or keep aspect ratio and change just one).
- Choose output format and quality (JPEG/WebP use quality; PNG is lossless).
- Process all images in one click, then download individually or as a batch.
- Everything runs locally in your browser - nothing is uploaded to any server.
