What is an image resizer?

An image resizer changes photo width and height in pixels for web, social, or print. Resize locally in your browser and download the scaled image.

Resize photo for web when full-resolution camera files slow your site. Scale to display width, then compress for faster LCP and lower bandwidth.

Match image width to CSS max-width—oversized assets are the top cause of slow LCP.

Use 2× sizes only for retina hero images, not every inline photo.

How to use this tool

Upload the photo, set width to your layout max (often 1200–1600 px), download, then compress if still large.

Worked example

Example: resize a banner from 2400×800 to 1200×400 for faster email newsletter load times.

When to use this

  • Blog posts with camera JPEGs.
  • Marketing landing pages.
  • Newsletter hero images.

Common examples

  • 4000×3000 phone photo → 1200×900 for a blog content column at 2× retina width.
  • LinkedIn headshot 2000×2000 → 800×800 avatar export.
  • Banner 2400×800 → 1200×400 for faster email newsletter load times.
  • 3000×2000 blog hero → 1600×1067 for faster LCP while keeping 3:2 ratio.
  • Square logo 1024×1024 → 256×256 favicon source before Favicon Generator.

How it works

Upload a JPG, PNG, WebP, or GIF image, choose new dimensions or a scale percentage, and download the resized file. Aspect ratio can be locked, and you can keep the original format or export as JPG, PNG, or WebP. Resizing works on your device—files are not uploaded or stored.

Limitations

Upscaling cannot recover detail that was not in the original image. Extreme aspect-ratio changes may crop or distort if not constrained.

Privacy and file handling
