About Image Resizer

Informational only, not professional advice. Report an error.

Need an image at exact pixel dimensions for a blog hero, Open Graph card, app store screenshot, or thumbnail? This image resizer scales photos to the width and height you specify while optionally preserving aspect ratio so nothing looks stretched.

Common workflows include resizing down for web performance (smaller dimensions usually mean faster page loads), generating social preview images at 1200×630, or preparing square assets for profile avatars and app icons.

Processing happens entirely in your browser. Combine with the Image Compressor after resizing to minimize file size before uploading to your site or CMS.

Common use cases

  • Shrink photos before uploading to a CMS, form, or email attachment.
  • Resize or crop assets for social previews, thumbnails, and app store screenshots.
  • Convert between JPG, PNG, WebP, and other formats when a platform requires a specific type.
  • Extract or preview text from screenshots when you need a quick copy-paste starting point.
  • Pair with Photo Filters when you need both dimension changes and smaller file size.
