Image Resizer

When locked, changing the width or height dynamically calculates the other dimension based on original proportions, avoiding any distortion.

Yes. All computations are sandboxed client-side in your local browser memory. Files are never uploaded.

Upload the image, enter the target width and height (or a percentage), optionally lock the aspect ratio, and download the resampled result.

Not if aspect-ratio locking stays enabled — changing one dimension scales the other proportionally, preventing distortion.

Resize to the largest display size actually needed, then convert the result to an efficient format like WebP with the WebP Converter — the combination yields far smaller files than resizing alone.
