Share a link on Facebook with the wrong image shape and the preview collapses into a small thumbnail nobody clicks. The size Facebook itself recommends for link posts is 1200 × 630 pixels, and this free tool opens with exactly that preset loaded. Upload the image from your article, product or event, pick how it fits, and download a post-ready file in seconds.
Square (1080×1080) and portrait (1080×1350) feed presets are built in too, because photo posts and link posts obey different shapes. Everything runs in your browser — no upload to our servers, no watermark, no sign-up, no fee.
Why 1200×630 is the Facebook link-post size
When you paste a URL into Facebook, the platform builds a preview card from the page’s Open Graph image. Facebook’s guidance for that image is a 1.91:1 ratio at 1200×630 pixels: large enough to render as the full-width card on desktop and mobile, sharp enough to survive the feed. Smaller images risk being demoted to the cramped side-thumbnail layout; odd ratios get cropped unpredictably. If you control the image — your own article’s featured image, a product shot, an event graphic — resizing it to exactly 1200×630 before you publish removes the guesswork. The same 1200×630 file doubles as the Open Graph and X/Twitter card image on your own website, which is why our website resizer carries it as a preset too.
Photo posts are a different animal
When the image is the post (no link), the feed rewards vertical real estate. A 1080×1080 square is the reliable all-rounder — it renders identically on phones and desktops and suits product shots, quotes and before-and-afters. A 1080×1350 portrait (4:5) takes noticeably more screen as people scroll, which is why photographers and coaches favour it. Both presets are one click in this tool. What about cover photos? They are a separate size again (820×312 on desktop, 640×360 on mobile) — you can type those numbers straight into the width and height fields here and use the same Fill/Fit controls.
Fill, fit, and the text question
For photographs, Fill centre-crops to the target shape with zero distortion — the safe default. For infographics, menus and anything with edges that matter, Fit keeps every pixel visible and pads the sides with your chosen background colour. And a persistent myth, retired: Facebook’s old “20% text rule” for ad images was abolished years ago — text-heavy images are no longer throttled for containing text. Legibility still matters for humans, though: at feed size, keep headline text big, high-contrast and well inside the frame, because mobile crops can nibble the edges of a 1200×630 card on some placements.
Pages, groups and events
The same sizes apply whether you post as a Page, in a group, or on an event — the feed renders them identically, and event cover images accept the 1200×630 family happily. Resize once here, post everywhere, and your announcement looks designed instead of improvised. If the post also goes to LinkedIn, note that its recommended shape is a near-twin (1200×627) — our LinkedIn resizer is preset to exactly that.
Marketplace and ads run on the same files
Two more Facebook surfaces reward the same discipline. Marketplace listings display photos in square frames, and listings shot and sized as clean 1080×1080 squares — Fit mode on white for products — consistently look more trustworthy than random phone crops. Ads built in Ads Manager reuse the feed placements, so the 1200×630 link image and the 1080×1080 square you export here drop straight into ad creative without a second design pass. Build the two files once, at publish time, and the organic post, the listing and the ad all carry the same sharp, deliberate image instead of three different compromises.
