Resize and optimise an image on your device. Your original stays unchanged, and this tool does not upload your image to Roled or another service.

What to expect
Resizing can reduce large images to the dimensions you need. JPEG and WebP quality controls trade detail for file size. Results depend on your image and browser.
Output keeps the detected input format. PNG and supported WebP output retain transparent areas. JPEG is opaque. This tool does not convert between formats.
Visible orientation is applied using your browser's image decoder. Re-encoding can change colours and metadata; original metadata and ICC profiles are not guaranteed to survive. This is not a metadata-removal or privacy-sanitisation tool.
Image contents are processed in browser memory without upload or browser storage. Reset clears this tool's references and download link. Very slow browser operations must finish before another image can be processed.
