Facebook Image Resizer

Your images are processed locally in your browser and never uploaded to any server.

Facebook favors 1200×630 for feed images and link cards, 851×315 for page covers, 320×320 for avatars. Wrong sizes get cropped or blurred by Facebook's own resampling. This tool hits the exact dimensions first, locally in your browser.

How to use the facebook image resizer

  1. Upload your image.
  2. Pick the preset matching where it will appear: post, cover, or profile.
  3. For covers, remember mobile crops the sides: keep the subject centered.
  4. Download and upload to Facebook.

Frequently asked questions

What is the best size for Facebook posts?

1200×630 (1.91:1) is the universal feed image. It fills link cards and looks right in the timeline. Square 1080×1080 also performs well for direct photo posts.

Why does my cover photo look different on mobile?

The 851×315 cover is desktop-shaped; the mobile app crops the sides to roughly the central 640px. Design for the center, or upload and check on both before announcing anything important.

Does Facebook compress images?

Aggressively. It re-encodes to JPEG around 100–200KB for feed images. Starting from an exact-size, high-quality source gives the recompression the best possible input, which is the main lever you control.
