How this tool works
JPEG, PNG, and WebP images are resized locally in your browser with proportional scaling and high-quality browser smoothing.
- Choose one or more JPEG, PNG, or WebP images.
- Enter the target width and height, keeping the aspect ratio locked by default.
- Process the queue and download files named with their actual dimensions.
Processing stays inside a disposable browser worker. Canceling or leaving the page terminates that worker and releases its memory.

- When both dimensions are supplied with the aspect ratio locked, width drives the derived height.
- Upscaling is allowed but does not add image detail.
- Target dimensions above 40 megapixels are rejected and no server fallback is used.
