About Free Image Resizer — Resize Your Image Online Instantly
WeLuvTools Image Resizer is a free browser-based tool for changing the pixel dimensions of JPG, PNG, and WebP images.

Keep the aspect ratio locked to prevent stretching, preview the target proportions, choose JPEG or PNG, adjust JPEG quality, and download the finished image.
