LinkedIn profile photos and post photos have different upload requirements

A headshot and a feed graphic do different jobs. Choose the destination first so you do not shrink a post to avatar dimensions or apply the wrong file limit.

Two uploads, two sets of numbers

For a profile photo, LinkedIn’s troubleshooting page gives a maximum of 8 MB, PNG or JPG, and pixel sizes between 400 × 400 and 7680 × 4320. It does not support GIF profile photos. The 400 × 400 figure is the lower end of that published range, not a requirement to reduce every headshot to exactly that size.

For photos shared in posts, the separate photo-sharing page gives a 5 MB upload limit, a minimum of 552 pixels wide by 276 high, a recommended width of 1080 pixels, and aspect ratios from 3:1 to 4:5. It also allows up to 20 photos in a multi-photo post. These are organic photo-post instructions, not advertising or article-cover specifications.

Prepare a profile picture around the face

Start with a clear portrait and leave some space around the head. Preview the circular profile display on LinkedIn before saving; useful parts of a square image can still fall outside the circle. Compression changes the bytes, not the position of your face.

Crop in your image editor if needed. The current CompressImageTo manual resize does not offer an interactive crop. Use the profile preset for a square source if its working size suits you, or keep a larger suitable portrait and use the custom compressor. Do not enlarge a tiny image and expect to recover missing facial detail.

Choose JPEG for an ordinary opaque photograph or PNG where that suits the source. If the original already uploads and looks clear, a smaller file is optional. There is no need to adopt a tiny government-form target for a professional headshot.

Prepare a post around the information

A feed graphic may contain a chart, product detail or text. Judge it at a realistic reading size before export. Thin lettering and cramped labels can become hard to read long before the file reaches the upload ceiling.

A square canvas is a practical option; so is a portrait canvas within the published ratio range. For example, 1080 × 1350 is a calculated 4:5 layout using LinkedIn’s recommended width. It is an editorial example, not a single mandatory post size. Keep important text away from edges and inspect the composer’s preview.

Use manual Resize and compress for a post, rather than the profile picture preset. Enter a width appropriate to your design and leave Keep aspect ratio on. If you only enter width, height follows proportionally. Crop in an editor first when you need a different shape; do not stretch a chart to fill a new rectangle.

Choose compression settings for the destination

The compressor’s Target size field is in KB using 1,024 bytes per unit. As practical safety targets, 7500 KB for a profile copy is 7,680,000 bytes, while 4500 KB for a post copy is 4,608,000 bytes. Both leave space below the respective decimal MB limits. They are suggested ceilings for preparation, not promises about the size your source will produce.

Set Output format deliberately, process the image, and read the result dimensions and format as well as Target status. For a text-heavy design, compare a PNG export with a JPEG export visually rather than assuming the smaller one is better. Return to the master file for another attempt.

The cited post-sharing page does not provide a complete format list. Do not copy the profile page’s PNG/JPG restriction over to posts as though it were the same specification. JPEG and PNG are practical export choices here, while the live composer remains the place to confirm what your upload accepts.

Review before you publish

Download and open the prepared file, then inspect it in LinkedIn’s composer. For multi-photo posts, check the arrangement as well as individual files: LinkedIn says the first photo influences the layout. Add useful alternative text before posting.

LinkedIn’s sharing guidance says uploaded photos cannot be edited or resized after posting. Inspect the image, crop and text first. A successful local result verifies the selected file settings; it does not guarantee how every LinkedIn surface will crop or recompress the picture.
