When should I resize?

  • You know the exact space an image should fill (e.g., 1200×630 cover).
  • A huge photo slows your page; downsizing saves bandwidth.
  • You want a uniform gallery where all images match sizes.

Quick tour of the screen

Resizer overview The Resizer screen with the upload area, size inputs, fit mode, and action button.

  • Upload area: drop or pick images to resize.
  • Width/Height: your target size. You can fill one or both.
  • Fit mode (cover/contain):
    • Cover: fills the box completely (may crop edges).
    • Contain: fits the whole image inside (may leave empty margins if different shape).
  • Output format: choose file type (e.g., WebP, JPG, PNG).
  • Resize/Download: the action to produce the new file.

Step-by-step: Resize an image

  1. Open: Image Resizer
  2. Add your image(s) with “Choose Files” or drop them in.
  3. Enter a Width (e.g., 1600). Height is optional — the tool can keep proportions if you leave it empty.
  4. Choose Fit mode:
    • Use Cover for banners/hero images when you want a precise crop.
    • Use Contain for product images you don’t want cropped.
  5. Pick the output format (WebP is a great default for the web).
  6. Click Resize, then Download your new image.

Enter size Enter width/height and adjust Fit mode.

Result Preview and download your resized image.

Tips

  • For web banners, 1600–1920px width is often enough.
  • Don’t upload a 6000px image if it will be shown at 800px — you’ll save a lot by resizing first.
  • Choose WebP for smaller files without obvious quality loss.

Troubleshooting

  • If the image looks cropped unexpectedly, switch Fit mode to Contain.
  • If you need a transparent background, stick to PNG or WebP.
