LinkedIn Banner Size: Making the 1584 × 396 Cover From a Photo

The short answer

LinkedIn recommends 1584 × 396 pixels for the banner on a personal profile. Its help pages call it the cover image, and in places the background photo. The file has to be a JPG or a PNG under 8 MB. The shape is a strip four times as wide as it is tall: 4:1.

A phone photo gets there in one step or in two. In one, YouTube Thumbnail Maker at a custom size of 1584 × 396 fills the strip from the middle of the photo. In two, Crop Image at 4:1 lets you choose the strip, and Resize Image scales it to 1584 pixels wide.

All three are free, need no sign-up and run in the browser tab; the photo is not sent to our server. We tried both ways on October 21, 2026, with two 12-megapixel photos. Every profile banner came out at exactly 1584 × 396 pixels and under 350 kB.

What LinkedIn asks for

The quotes come from LinkedIn Help, checked on October 21, 2026. The page “Add or change the cover image on your profile” lists the specifications: “JPG or PNG file”, “Lesser than 8MB” and “1584 (w) x 396 (h) pixels (recommended)”.

The help page on photos that won't upload calls the same slot the background photo: “Recommended pixel dimensions are 1584 (w) x 396 (h) pixels.” It adds “File type must be PNG or JPG”, “Maximum file size is 8MB” and “We don't support GIFs.”

Two notes matter for the design. “Your cover image appears behind your profile photo in the introduction section on your profile.” And “How your image appears may change based on the size of your web browser window and screen resolution.” Once the banner is up, look at your profile in a wide window and on a phone.

One step: Thumbnail Maker at a custom size

The tool is named for YouTube, but its Custom size takes any width and height from 320 to 4096 pixels. Drop the photo, choose Custom size under “For which platform” and type 1584 in Width and 396 in Height. Under “How the photo fills the frame”, keep Cover. Leave Title empty unless you want words on the banner.

Our landscape test was a 4032 × 3024 phone photo of a mountain lake, 5,328,211 bytes. The strip was ready about half a second after we typed the height. Download JPG gave a 1584 × 396 file of 282,593 bytes.

Cover scales the photo until it fills the strip and trims the rest evenly from both sides. The crop always sits in the middle, and nothing on this page moves it. From our 4:3 photo, it kept the middle third of the height: the lake and the hillsides around it, without the sky.

Thumbnail Maker always writes a JPG, at quality 88, whatever comes in. A PNG or WebP photo leaves as a JPG, one of the two formats LinkedIn takes.

Two steps: Crop Image picks the strip, Resize Image sets the size

Drop the photo, choose Custom under “Aspect ratio” and type 4:1 in “Custom ratio (N:M)”, which starts at 5:4. Type 4:1 rather than 1584:396, since the field takes up to three digits a side. On October 21, 2026, a four-digit ratio left the frame free, with no message.

The first 4:1 frame spans 80 percent of the width, 10 percent in from the top and left. On our lake photo, that meant 3226 × 806 pixels of sky and distant mountains. Drag the frame, or type exact numbers under “More settings”: X position, Y position, Width and Height.

We typed 0, 1008, 4032 and 1008: the middle strip Thumbnail Maker took, across the full width. Result file, under the photo, showed the exact size: 4032 × 1008. The row under Download JPG takes the crop on without a download. Choose Resize Image, and the page says “Continuing with the file from your last step”.

It opens on Percentage. Under “Set size by”, choose Exact pixels and type 1584 in Width. Leave Lock aspect ratio on and Height empty: the size above the picture should read 1584 × 396. Download JPG gave exactly that, 344,762 bytes, about a fifth heavier than the one-step file. Resize Image saves JPG at quality 90.

Each result was ready within about one and a half seconds, in Chromium on a Mac. Crop Image and Resize Image keep JPG, PNG and WebP in their own format, so a WebP stays a WebP, which LinkedIn does not list.

What is left of an upright photo

A 4:1 strip holds little of a tall photo. Across the full width of an upright 3024 × 4032 photo, it is 3024 × 756 pixels: 18.75 percent of the height. Our test was a tree in autumn color, 5,587,059 bytes.

Thumbnail Maker kept the middle 756 rows, 1638 to 2394: leaves and branches, without the top of the crown or the foot of the trunk. The file weighed 254,148 bytes.

Crop Image started its 4:1 frame near the top instead: 2419 × 605 pixels, from Y 403. Dragged down, it kept its size, and the numbers under “More settings” followed it. Typed as the full-width middle strip, 3024 × 756, it came out of Resize Image at 330,089 bytes.

To keep the whole tree, switch Thumbnail Maker to Contain. The photo shrinks to about 300 pixels wide in the middle, and the sides fill with black, a color you can change under “More settings”. That file weighed 70,693 bytes.

Final checks, and the size for a company Page

Check three things: JPG or PNG, under 8 MB, 1584 × 396 pixels. Ours were all JPG; the heaviest, 344,762 bytes, used under 5 percent of the limit. None of the three tools opens HEIC, so an iPhone photo in HEIC goes through HEIC to JPG first.

Start from the full-size photo, not a screenshot of it. Thumbnail Maker enlarges a smaller picture to fill the strip, and an enlarged picture looks soft. Resize Image keeps a smaller picture at its own size instead.

Neither way sends the photo to our server. Our lake photo carried its capture date, GPS position and camera model; none of the banners did.

A company Page is a different slot. LinkedIn's help on Page images gives 1512 (w) x 256 (h) pixels as both the minimum and the recommended cover size, PNG or JPEG, at most 3 MB. Thumbnail Maker's sides start at 320 pixels, so it cannot make that strip. In Crop Image, type 189:32, which is 1512:256 in smaller numbers, then resize to 1512 wide. We got 1512 × 256 pixels and 44,922 bytes.
