The instruction to resize image to 1200x628 comes from ad managers, sharing checklists and blog templates, because 1200 × 628 pixels is the 1.91:1 landscape frame that link cards and single image ads are drawn in. LinkedIn’s help centre gives exactly that figure for horizontal single image ads and at least 1200 by 627 for link images; Meta’s sharing documentation puts the same shape at 1200 × 630 or larger. The three heights are one proportion rounded three ways.
This page is preset to 1200 wide and 628 tall with Crop to fill switched on. A photo of any shape is scaled until it covers the frame, the overflow along the two long edges is cut away in equal amounts around the centre, and the file comes back as a JPG, PNG or WebP of exactly 753,600 pixels, in the format it arrived in.

The dashed frame on the left marks the part that fits the new shape. It was scaled to exactly 1200 × 628 px, and the top and bottom outside the frame were trimmed.
The file went from 464 KB to 163 KB.
The image on the right is the actual file the tool above produced.
How to use it
- Add the photo, screenshot or design export. Start from the largest copy you have; a picture already wider than 1200 pixels only shrinks.
- The resize runs on its own and the preview shows the 1200 × 628 result built around the centre of the original.
- Look at the two long edges. If a face, a logo or a line of text has been cut, open the crop tool, draw a free frame about 1.91 times wider than it is tall where you want it, and bring the result back here.
- Download. A JPG at this size usually weighs 150 to 400 KB, well under the 8 MB Meta allows for a link image and the 5 MB LinkedIn allows for an ad.
Why 628, 630 and 627 are the same frame
Divide 1200 by 1.91 and you get 628.27, which rounds to 628. Meta’s sharing documentation describes the ratio as 1.91:1 but quotes the example size as 1200 × 630, which is 1.905:1, and LinkedIn’s sharing module asks for a minimum of 1200 by 627, which is 1.914:1. The gap between the three is one or two rows of pixels, well inside the three per cent aspect-ratio tolerance that Meta’s feed ad guide allows.
So one 1200 × 628 file serves a Facebook link card, a LinkedIn post and a LinkedIn single image ad. If a template insists on 630, type 630 into the height box before adding the file; the crop is recomputed for the new frame. In whole numbers the ratio is 300:157.
What the crop removes from each kind of picture
A frame this wide keeps only a horizontal band of most pictures. A 4:3 landscape phone photo loses 30 per cent of its height, 15 from the top and 15 from the bottom. A 3:2 camera frame gives up about a fifth, and a 16:9 screenshot or video frame loses only seven per cent.
A square picture keeps 52 per cent of its height and loses 24 per cent at each end; a 1080 × 1080 export is also enlarged to 1200 wide first. A 3:4 portrait keeps under 40 per cent and a 9:16 story under 30 per cent: a narrow slice, enlarged, with the top and bottom gone. For those shapes Lock aspect ratio returns the whole picture at 628 × 628 or 471 × 628, below LinkedIn’s 640-pixel minimum ad width and Meta’s 600-pixel floor; the better route is to set the portrait on a 1200 × 628 background in an editor.
Safe zone, text and the ad guides as they stand today
Meta’s sharing documentation says a 1.91:1 image shows in full in the feed, so on a Facebook link card the whole frame is visible. Where the same picture is reused as a square, a centred 628 × 628 crop drops 286 pixels on each side. Keeping headlines, logos and faces inside the middle 628 pixels, about 40 pixels clear of the top and bottom edges, means the picture still reads whichever crop a placement applies.
The ad guides have moved on from this size for feed placements. Meta’s current Facebook feed image ad page recommends 4:5 at 1440 × 1800 pixels, JPG or PNG, with a 600-pixel minimum width, and no longer lists 1200 × 628. LinkedIn still gives 1200 × 628 as the recommended horizontal single image ad size, with 1200 × 1200 for square and 720 × 900 for vertical. A square or 4:5 version is worth preparing alongside the landscape file.
Frequently asked questions
- Is 1200 × 628 the same as 1200 × 630, and what ratio is it?
- In practice, yes. Both are the 1.91:1 landscape ratio rounded differently: 1200 ÷ 1.91 gives 628, and 1200 × 630 is 1.905:1. Two pixels of height are invisible on screen; type 630 into the height box if a template asks for it.
- What is 1200 × 628 in inches or centimetres?
- On its own, nothing: the size exists for screens, where only pixels count. If a layout program needs a document size, 1200 × 628 at 96 DPI is 12.5 × 6.54 inches, or 31.75 × 16.62 cm. The file from this page carries no DPI value because the preset works in pixels.
- Will my photo be stretched to fit?
- No. Crop to fill keeps the proportions and trims the overflow around the centre. Stretch is available, but it distorts faces and lettering.
- Can I use this for an Open Graph og:image?
- Yes. LinkedIn’s sharing module asks for at least 1200 by 627 pixels at 1.91:1 and under 5 MB, which a 1200 × 628 JPG meets. Meta’s sharing documentation asks for a ratio close to 1.91:1, a file under 8 MB and at least 1200 × 630 for high-resolution screens, so set the height to 630 if you want to match Meta’s number exactly.
- Does it keep PNG transparency and sharp text?
- A PNG stays PNG, so transparency and crisp lettering survive. A JPG stays JPG at quality 92; HEIC and other formats are written as JPG. For flat colours and logos keep PNG, and convert to JPG afterwards if a file-size cap bites.
