What is an Image Resizer?
This image resizer is a free online tool with two output modes. Padding mode scales your image to fit target dimensions and fills any extra space with a background color you choose—ideal for fixed-size layouts (ads, social, thumbnails). Fit mode outputs the full image at its natural aspect ratio, shrink-only, with no padding. Export as PNG, JPG, or WebP. All processing runs in your browser.
Why Choose Our Image Resizer?
Our image resizer is 100% client-side—your images never leave your device. The image resizer interface is grouped for clarity: choose Output Mode (Padding or Fit), set Dimensions (width × height, optional background or force exact size), pick Output Format (PNG/JPG/WebP), then use More Options for Retina 2x and compression. Fast, free, and private.
Struggling to Fit Images into Fixed Dimensions?
Specs often require exact sizes like 800×600. Cropping loses content; stretching distorts. Use this image resizer in Padding mode to scale proportionally and fill with your chosen background—exact size, no crop. Or use Fit mode for full-image output. Perfect for creatives, social posts, and thumbnails.
