Image Resizer
Resize an image to a target width and height, optionally keeping the aspect ratio, then export as PNG, JPEG, or WebP with an adjustable quality. Use percentage presets or enter exact pixel dimensions. The image is decoded and resampled entirely in your browser on a canvas — nothing is uploaded. Large images are downscaled with the browser's built-in smoothing; for upsizing, nearest/bilinear smoothing applies.

PNG, JPEG, WebP, GIF, BMP — processed locally.
Choose an image, set the target dimensions (or a scale percentage), pick a format, and click Resize & preview. The result is rendered on a canvas in memory; Download saves the resized file. Quality affects JPEG and WebP only (PNG is lossless). Everything runs locally in your browser.
