LinkedIn Post Image Resizer

A link post and a photo post are different things

This is the distinction most guides get wrong, and it is why a single recommended size cannot be right for every LinkedIn image. A 1,200 by 627 image is LinkedIn recommendation for a **link post**, meaning the image sits beside a shared URL as its preview. A **photo post**, where the image is the content, accepts a much wider range of aspect ratios, from 3:1 down to 4:5, with at least 552 by 276 pixels and about 1,080 pixels wide recommended. Converting a square or portrait photo to 1.91 to 1 for a photo post is unnecessary, and converting a wide banner for a link post to 1.91 to 1 is usually right. The question is which kind of post you are making.

The file limits that also apply

Beyond dimensions there are three limits worth knowing, because they are enforced rather than advisory. Each photo upload is capped at 5 MB, so a large modern image needs compressing before it will be accepted. Images can be up to 36 megapixels, which is generous enough that no ordinary photo hits it. Supported formats include JPG, JPEG, PNG, and WebP, so a modern format is accepted rather than rejected. The 5 MB cap is the one that catches people, because a 12 megapixel phone photo straight from the camera will usually exceed it.

• Each photo upload is capped at 5 MB.
• Images up to 36 megapixels are accepted.
• JPG, JPEG, PNG, and WebP are all supported.
• A large phone photo usually exceeds 5 MB and needs compressing first.

NoteThe 5 MB cap is enforced. A 12 megapixel photo from a camera will usually exceed it.

What the feed does to a ratio it does not like

The feed crops rather than letterboxing, and the crop is usually central, which means a face or a logo near an edge is the first thing lost. A portrait photo forced into a wide frame loses a large part of its height. The reason to match the ratio is that it keeps the decision with you rather than with the platform, and since the target sizes are small, a correctly proportioned export is also a lighter file, which loads faster in a feed people scroll on a phone.

• LinkedIn crops rather than adding bars, usually toward the centre.
• A portrait image in a wide frame loses a lot of its height.
• Keep faces and logos in the horizontal centre.
• A correctly proportioned export is also a smaller file.

Fitting your image to the frame

A landscape photo is wider than 1.91 to 1, so filling the frame crops the top and bottom, which usually works because the excess is sky or foreground. A portrait photo or a screenshot is taller, so padding the sides preserves the whole subject and usually looks better. Where the subject position matters, crop it yourself first, where you can see what you are keeping, and then resize. The controls offer both fitting modes and the choice is worth making deliberately rather than accepting whatever the default does.

• Landscape photo: fill crops the top and bottom. Usually correct.
• Portrait photo: pad the sides rather than cropping the subject.
• Set the padding colour to match the design, or the bars look accidental.
• Crop yourself with the image cropper when placement matters.
