Scale image online free when you need exact pixel dimensions for web, social, or print prep. Upload, set width and height, and download—no desktop editor required.

Scaling down preserves quality; scaling up beyond original pixels adds blur—start with the largest source available.

Upload your image, enter target width and height (or lock aspect ratio), then download the scaled file.

How it works

Upload a JPG, PNG, WebP, or GIF image, choose new dimensions or a scale percentage, and download the resized file. Aspect ratio can be locked, and you can keep the original format or export as JPG, PNG, or WebP. Resizing works on your device—files are not uploaded or stored.

Limitations

Upscaling cannot recover detail that was not in the original image. Extreme aspect-ratio changes may crop or distort if not constrained.

Privacy and file handling

Your data stays on your device and is not uploaded.
