How to Resize an Image for a LinkedIn Post
A LinkedIn post image needs the right frame, enough clarity for professional content, and a file size that does not invite ugly platform recompression.
LinkedIn dimensions and format
Landscape and square layouts are common starting points for LinkedIn feed posts. The key is to size for the post frame you expect instead of uploading a giant source and letting the platform decide. JPG for photo-heavy posts and PNG for text-heavy visuals where edge clarity matters is usually the safest format here — it balances compatibility, predictable rendering, and a reasonable file weight for the platform.
Workflow that works
Choose the feed frame first, crop if needed, resize to the real post dimensions, and then use moderate compression so text and faces remain clean.
Real examples
A thought-leadership post with a speaker photo usually works well as a clean JPG. A hiring graphic with large text may justify PNG or another sharper output if the labels need to remain crisp. A carousel cover image benefits from deliberate crop control so the focal point does not drift.
How it affects reach and distribution
The same LinkedIn image is often reused on blogs, landing pages, or case studies later, so sizing and format discipline still pays off on owned properties.
Developer and operations notes
Teams benefit from a defined LinkedIn preset so social assets stay consistent across contributors and campaigns.
Common mistakes to avoid
- Uploading oversized originals and trusting the platform to handle the resize gracefully.
- Using a wrong aspect ratio that crops out the main subject in feed preview.
- Over-compressing text-heavy graphics so professional polish is lost.
- Ignoring how the image will appear on mobile feed views.
Exact pixel dimensions for every LinkedIn surface
LinkedIn renders feed images inside a column roughly 552 px wide on desktop and full-width on mobile, then downsamples your upload to fit. Upload at the native dimensions below so the only resampling that happens is a clean reduction, never an upscale. The platform crops anything taller than 4:5 in the feed preview, so a 9:16 vertical graphic loses its top and bottom unless it lives in a document or video slot.
Use these exact dimensions and aspect ratios for each LinkedIn placement:
- Single-image feed post, landscape: 1200 x 628 px (1.91:1).
- Single-image feed post, square: 1200 x 1200 px (1:1).
- Single-image feed post, portrait: 1080 x 1350 px (4:5) — the tallest ratio shown uncropped in feed.
- Shared-link / article thumbnail (og:image): 1200 x 627 px (1.91:1); below 1200 px wide LinkedIn may fall back to a small square thumbnail.
- Document (PDF) post pages, the native carousel: 1080 x 1080 px (1:1) or 1080 x 1350 px (4:5), one ratio held across all pages.
- Profile photo: 400 x 400 px minimum, displayed as a circle; upload 600 x 600 px for retina sharpness.
- Profile background / cover banner: 1584 x 396 px (4:1).
- Company Page logo: 300 x 300 px; Company Page cover: 1128 x 191 px.
File-size ceilings and the quality settings that survive LinkedIn's re-encode
LinkedIn re-encodes nearly every inline image to its own JPEG, so your goal is to hand it a file that needs almost no further compression. Inline feed images have a hard 5 MB upload limit; stay well under it. For a 1200 x 1200 photo, target 300 to 600 KB, and for a 1200 x 628 landscape, 200 to 400 KB. At those weights LinkedIn's pass leaves edges and skin tones intact; arrive at 3 to 5 MB and its encoder crushes the file harder, smearing fine text and introducing visible 8x8 block artifacts around high-contrast type.
Export photographs as JPEG at 80 to 85 percent quality in the sRGB color space — LinkedIn assumes sRGB and will shift colors on Adobe RGB or P3 files. Use PNG-24 only for graphics with large flat areas, hard edges, or fine text such as hiring cards and quote graphics, where JPEG's chroma subsampling fuzzes lettering; a 1200 x 1200 PNG of that kind typically lands at 150 to 500 KB. Skip PNG for photos, where it can balloon past 3 MB for no visible gain. DPI tags are irrelevant here because LinkedIn renders by pixel count, not print resolution, so a 72-DPI and a 300-DPI file at identical pixel dimensions look the same and weigh the same. Document (PDF) posts allow up to 300 MB and 300 pages, but keep each exported page under about 1 MB so the carousel loads fast on mobile.
A sized export checklist before you hit Post
Run these steps in order with the site's Crop Image, Resize Image, and Compress Image tools to land within LinkedIn's tolerances on the first upload and avoid a second round-trip through its encoder:
- Pick the surface and its target ratio first: 1.91:1 for landscape, 1:1 for square, or 4:5 for portrait — decide before cropping so the focal point is never cut.
- Crop Image to that exact ratio, keeping faces and logos at least 80 px clear of every edge so LinkedIn's circular and rounded-corner masks never clip them.
- Resize Image to the native pixels for that surface — 1200 x 628, 1200 x 1200, or 1080 x 1350 — and never enlarge a source smaller than the target, which only adds soft, mushy pixels.
- Compress Image to JPEG at 80 to 85 percent (or PNG-24 for text-heavy graphics) and confirm the result sits in the 200 to 600 KB band; if a JPEG exceeds 1 MB, drop quality 5 points rather than letting LinkedIn do it for you.
- Verify the export is sRGB, then preview on a phone-width window, because the mobile feed is where most impressions land and a 12 px caption that reads fine on a 27-inch monitor can become unreadable at phone scale.
