What is this tool?

Facebook Post Resizer prepares images for link-style and feed-friendly Facebook post layouts using a 1200x630 preset. This wide format is useful for shared links, blog previews, promotions, announcements, and images that need to look clean in the feed.

A Facebook post image should communicate quickly. Keep the subject clear, avoid tiny text, and make sure important details are not too close to the edges. If the image will also be used on a website or in Open Graph previews, the wide 1.91:1 composition is especially useful.

This tool helps you create a predictable output before uploading or publishing. If your original image is vertical or square, decide whether cropping or adding canvas space makes the better post preview.

Limitations to know

Social platforms can crop, recompress, or display images differently across devices after upload.
Platform size recommendations can change, so preview important posts or profile images after uploading.
Very large images can require more device memory and may process more slowly on phones or older computers.
The exported file is a new browser-generated copy, so you should keep your original file if you may need to edit it again.
