How it works

Complete the job in three clear steps

  1. Add an image and target dimensions to the local workspace.
  2. Choose the relevant settings and create a high-quality resized image.
  3. Review the result carefully, then copy or download it before leaving the page.

Important

Check the result before relying on it

Keep an untouched copy of important source files. Browser processing depends on available device memory, and you should inspect every downloaded result before deleting the original.
