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.

How to use

Upload an image by clicking or dragging into the drop zone.
Set your desired width and height in pixels, or choose a common preset (e.g., passport photo, social media).
Toggle aspect ratio lock on/off depending on your needs.
Download the resized image.

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.
