Straight answer: upload a square image at 800 by 800 pixels for the sharpest result on every device, though LinkedIn’s stated minimum is 400 by 400 pixels and its maximum is 20,000 by 20,000 pixels. The file needs to be a JPG, PNG or non-animated GIF under 8MB. Get the pixels right and your photo still won’t work if you ignore the circle crop, which is the part almost everyone gets wrong.
The exact numbers, straight from a spec sheet
Here’s what LinkedIn asks for, because the platform’s own help pages bury this across three different articles:
- Minimum size: 400 x 400 pixels
- Maximum size: 20,000 x 20,000 pixels
- Maximum file size: 8MB
- Accepted formats: JPG, PNG, GIF (static, not animated)
- Aspect ratio: 1:1, meaning a perfect square
If you take one number away from this post, take 800 by 800. It’s large enough to look crisp on a high-resolution phone screen, small enough not to slow down upload, and it gives you enough padding to crop without losing quality. I’ve tested 400 by 400 uploads next to 800 by 800 uploads on the same device and the smaller one goes slightly soft the moment someone taps to view it full screen. Nobody consciously notices “this photo is 400 pixels,” but people do notice “this photo looks a bit blurry,” and that reads as unprofessional even when the person in it is perfectly polished.
Why the “minimum” spec is the wrong target
Most guides on this topic stop at “LinkedIn’s minimum is 400×400, so use that.” That’s technically true and a bad idea. LinkedIn displays your photo at wildly different sizes depending on where someone sees it: a tiny 20-pixel circle next to a comment, a medium thumbnail in the search results, and a much larger version on your profile page itself. A 400 by 400 image gets stretched to fill some of those spaces, and stretched images pixelate. An 800 by 800 image gets compressed instead, which photos handle far better than expansion does.
There’s also a practical reason to go bigger than the minimum: you will crop this photo again. People change profile pictures every twelve to eighteen months on average in my experience working with clients, and every time you do, you’ll want room to recentre or reframe without starting from scratch. A bigger original file gives you that flexibility. A 400 by 400 file gives you nothing to work with.
The circle crop is where most photos fail
This is the bit that gets skipped in almost every “LinkedIn photo size” article, and it’s the reason perfectly good photos still look wrong once uploaded. LinkedIn displays your profile picture inside a circle, not a square. Your uploaded file is square, so the platform crops the corners off automatically, and it does this differently on desktop versus the mobile app.
I had a client, a management consultant based in Manchester, who sent me a beautifully shot headshot for his LinkedIn profile. Sharp, good lighting, professional photographer, the works. On his desktop preview it looked exactly right. On the mobile app, the crop had shaved off the top of his head and one shoulder, because the photographer had framed him close to the edges of the square and left almost no breathing room. He hadn’t noticed for four months because he was checking his own profile on desktop and never thought to check it on his phone, where the vast majority of his connections were seeing him.
The fix is simple and it’s the step almost nobody mentions: keep your face and shoulders inside the middle 70 to 80 percent of the square, with equal space around all four edges. Treat the outer edge of your square like a border you’re never allowed to use. If you’re framing your own photo in Canva or Photoshop before upload, position your eyes roughly a third of the way down from the top of the frame and leave visible space on both sides of your head. That space is what saves you when the circle crop clips in.
Step by step: getting the size right before you upload
- Start with the highest-resolution photo you have, ideally straight from a camera or phone, not a screenshot or a photo pulled off another website.
- Crop it to a perfect square using Canva, Photoshop, or even the built-in cropping tool in your phone’s photo app. Set the crop dimensions to a 1:1 ratio.
- Resize the square to 800 by 800 pixels. In Canva this is under “resize,” in Photoshop it’s Image, Image Size, with the chain link locked so it stays square.
- Leave a visible margin around your head and shoulders, roughly 10 to 15 percent of the frame on each side, so the circle crop doesn’t clip your hairline or your shoulder.
- Save as a JPG at high quality, ideally under 2MB even though LinkedIn allows up to 8MB, because a leaner file uploads faster and there’s no visible quality gain past that point for a headshot.
- Upload it, then check it in three places before you consider the job done: your profile on desktop, your profile on the mobile app, and the small comment-thumbnail version that shows when you post something.
That last step is the one people skip. If you’re posting regularly (and if you’re weighing up how often you should post on LinkedIn each week, that photo shows up next to every single one of those posts), your profile picture is doing far more visual work than most people realise. It’s not just sitting on your profile page waiting to be admired. It’s a tiny recurring stamp of credibility next to every comment, every post, every message you send.
File format and quality: what matters
JPG is the right choice for almost everyone. It compresses photographs well without visible quality loss at the file sizes LinkedIn is working with. PNG is only worth using if your image has sharp edges or text, which a headshot doesn’t, and PNG files are unnecessarily large for a photo, which slows your upload for no benefit. Skip GIF entirely for a profile picture; LinkedIn only accepts static GIFs anyway, so there’s no advantage over a JPG and the file format has a reputation problem that doesn’t help you look professional.
On resolution: don’t upload a photo pulled from an old website bio or a Facebook album from 2015. Those files are frequently compressed down to something like 200 by 200 pixels already, and no amount of resizing after the fact will add detail back in that was thrown away the first time. If your only available photo is low resolution, it’s worth spending the money on a new one rather than fighting a losing battle with an image that was never good enough to begin with.
The uncomfortable part nobody wants to say out loud
Here’s the bit that has nothing to do with pixels and everything to do with why people care about this topic in the first place. I’ve reviewed hundreds of LinkedIn profiles for clients over the years, and the profile picture that gets the most trust isn’t the most technically perfect one. It’s the most current one. I regularly see senior, credible, experienced people using a photo that is eight, ten, sometimes fifteen years old. Nobody tells them. Their connections just quietly notice the gap between the photo and the person on a video call, and it costs a sliver of trust every single time, even when nobody says anything about it.
A sharp, perfectly cropped, exactly 800 by 800 photo of you from a decade ago is still a photo of someone who no longer exists in that form. If you’ve changed your hair, put on weight, lost weight, gone grey, aged in any of the ordinary ways humans age, and your photo hasn’t kept pace, the size and quality of that image is the least of your problems. Update the photo itself before you worry about the pixel count. I say this as a 53-year-old woman who has updated her own profile picture more times than I can count over the years precisely because the version of me from five years ago isn’t who shows up to the client call.
Common mistakes I see on client profiles
- Group photos cropped down to a headshot, where you can still see someone else’s arm or shoulder at the edge of the frame.
- Photos taken at an angle where the person is off-centre, which the circle crop then chops in a way that looks accidental rather than intentional.
- Busy, cluttered backgrounds that compete with the face, especially at the small thumbnail sizes where a busy background just reads as visual noise.
- Heavy filters or beauty apps that make the photo look noticeably different from how the person looks in a video call, which undermines trust the moment you meet.
- Uploading a rectangular photo and letting LinkedIn’s automatic square crop decide the framing for you, rather than cropping it yourself first.
That last one matters more than people think. LinkedIn’s automatic crop tends to centre the image, which sounds fine until you remember most portrait photos aren’t shot with the subject dead centre. Do the cropping yourself before upload and you keep control of the framing instead of leaving it to an algorithm.
Why this connects to more than your profile page
Your profile picture isn’t a one-off task you finish and forget. It travels with everything else you do on the platform. If you’re building a case for whether posting on LinkedIn is worth it for your business, remember that every post, comment, and connection request carries this same small circular photo, and it’s often the first visual impression someone gets before they’ve read a word you’ve written. The same goes if you’re trying to grow a newsletter audience through LinkedIn: people subscribe to people, and the tiny photo next to your name is doing quiet work on every touchpoint along the way.
If you’re still deciding whether you should be posting on LinkedIn at all, get this piece sorted regardless of your answer. A correctly sized, well-cropped, current photo costs you twenty minutes and it’s one of the few things on your profile that’s entirely within your control, unlike engagement numbers or algorithm changes.
A quick real-world test
Before you consider your photo finished, do this: shrink your browser window or look at your profile on your phone, then squint at the thumbnail size, roughly the size of a comment avatar. If you can still tell it’s clearly you, with your face readable and not swallowed by background clutter, it passes. If you have to think about it, it’s too busy, too small a headshot within the frame, or too poorly cropped. This thirty-second test catches more problems than checking the full-size version ever will, because the full-size version is not where most people encounter your photo.
Frequently asked questions
What size should my LinkedIn profile picture be in pixels?
Upload a square image at 800 by 800 pixels. LinkedIn’s stated minimum is 400 by 400 pixels and its maximum is 20,000 by 20,000 pixels, but 800 by 800 gives you the sharpest result across desktop, mobile, and thumbnail views without an unnecessarily large file.
Does LinkedIn crop profile pictures into a circle?
Yes. Even though you upload a square image, LinkedIn displays it inside a circle everywhere on the platform, which means the corners of your square are always cut off. Keep your face and shoulders within the middle 70 to 80 percent of the frame so nothing important gets clipped.
What file format does LinkedIn accept for profile pictures?
LinkedIn accepts JPG, PNG, and static GIF files up to 8MB. JPG is the best practical choice for a photograph because it keeps quality high while keeping the file size reasonable for fast uploading.
Can a LinkedIn photo be too high resolution?
Not in terms of quality, but LinkedIn caps file size at 8MB, so an extremely high-resolution file may need compressing before it will upload. A well-compressed 800 by 800 JPG under 2MB gives you full quality without hitting any size limits.
