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.
Quick tips
- Use 1200×630 for Open Graph and Twitter card images.
- Enable maintain aspect ratio to avoid distorted faces or logos.
- Start from the highest-resolution source when enlarging images.
