Facebook Image Resizer
Resize
1.91:1, link & feed cards.
Saves the edited image at its current dimensions. JPG, PNG, and WebP keep their format; other supported inputs download as JPG. Check the downloaded file for final quality.
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.
Facebook is notoriously heavy-handed with images: it re-encodes almost everything to a small JPEG, and its automatic cropping treats a feed photo, a link card, and a cover as three different shapes. Feeding it a file already at the right dimensions gives that recompression the cleanest possible input, which is the single biggest lever you have over how sharp your image looks once it is live.
How to use the facebook image resizer
- Upload your image.
- Pick the preset matching where it will appear: post, cover, or profile.
- For covers, remember mobile crops the sides: keep the subject centered.
- Download and upload to Facebook.
Match the size to the placement
For ordinary posts and shared links, 1200×630 (1.91:1) is the workhorse: it fills the link-preview card and sits correctly in the timeline. A 1080×1080 square is a strong alternative for a standalone photo, since it occupies more height in the feed as people scroll.
Covers and avatars follow their own rules. The page cover is 851×315 on desktop but is cropped to the central strip on phones, so keep logos and text centered. The profile picture is a small circle, best served by a tightly-framed, centered subject. When in doubt, resize to the exact preset and keep anything important away from the edges.
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.
