How it works
Resize any image to exact pixel dimensions. Lock the aspect ratio to prevent distortion, or unlock it for custom proportions. All processing is done in your browser — no uploads needed.
Frequently asked questions
Upscaling (making an image larger) will reduce apparent quality since new pixels are interpolated. Downscaling generally maintains quality.
When locked, changing width automatically adjusts height (and vice versa) to maintain the original proportions, preventing stretching or squishing.
