Image Resizer

It changes the pixel dimensions of an image while keeping it sharp. You drop an image, type a target width or height, and download a resized copy as JPG, PNG, or WebP. The aspect ratio lock keeps your image from looking stretched.

Most images on the web are far larger than the space they fill, which wastes bandwidth and slows pages. A hero banner often needs only 1600 pixels wide, not 4000. Resizing once before upload is one of the fastest wins for site speed.

1. Drop your image into the upload area.
2. Type the new width. The height updates automatically when aspect ratio is locked.
3. Click Resize, choose a format, and the file downloads instantly.

Resize when you want the same composition at a smaller pixel size. Crop when you want only part of the original image. For square thumbnails on a rectangular photo, you usually need both, first crop to square, then resize to thumbnail size.
