LinkedIn 图片尺寸调整器 - 横幅、头像、帖子与文章尺寸

目前 LinkedIn 个人主页横幅尺寸为 1584 × 396 像素（4:1 比例）。公司主页封面为 1128 × 191 像素。两者都应导出为小于 8 MB 的 JPEG 或 PNG，以确保在各类设备上都能正常显示。

上传图片，选择 LinkedIn 个人横幅（1584 × 396）或公司主页封面（1128 × 191）预设，将焦点拖到安全区域内进行定位，然后下载。安全区域标记可确保 LinkedIn 头像不会遮挡重要文字。

让左下角区域（约 250 × 250 像素）保持空白，桌面端的头像圆圈就位于此处。编辑器会显示一个半透明遮罩，方便你将焦点放在右上角，使其始终清晰可见。

JPEG 最适合包含人物、办公场景或背景的照片类横幅——文件更小，在慢速连接下加载更快。对于包含清晰文字、徽标和渐变、压缩瑕疵会显现的横幅，PNG 更合适。

LinkedIn 在移动端和桌面端对横幅的裁剪方式不同。编辑器会同时预览两种视图，方便你确认关键文字和人脸都处于两端的安全区域内，避免移动应用中常见的「横幅被切成两半」的失误。

Yes. Your image is uploaded over HTTPS, resized on our secure servers, and deleted automatically once processing finishes — we never store, share, or sell it, so unreleased campaign visuals, executive headshots and confidential brand assets stay protected. If your policy requires images to never leave your device, use an offline desktop image editor instead.

Cover fills the target frame completely, cropping any excess — best for banners you want edge-to-edge. Contain fits the whole photo inside the frame without cropping, filling any empty space with your chosen background color. Stretch forces the image to exactly match the target size, which can distort people or logos if the aspect ratio is very different from your source photo.

Switch Fit to Contain, then use the Background color picker to fill the letterbox area — it defaults to LinkedIn blue (#0a66c2) so a logo on a transparent or plain background blends in, but you can pick any hex color to match your own brand instead.

Personal banner (1584x396), company banner (1128x191), profile picture (400x400), company logo (300x300), square logo (60x60), post image (1200x627), article cover (1280x720) and event cover (1776x444) — pick the preset for the placement you're uploading to and the exact pixel dimensions are applied automatically.

Yes — the Format selector includes JPEG, PNG, WebP and AVIF. WebP and AVIF typically produce smaller files at the same visual quality, which helps if you're hosting the image yourself rather than uploading straight to LinkedIn, which still expects JPEG or PNG on upload.

The Quality slider (40-100%, shown for JPEG/WebP/AVIF) controls compression — 85-92% is a good default that keeps text and logos crisp while staying well under LinkedIn's upload limits. PNG output ignores the slider since PNG compression is always lossless.

LinkedIn displays profile pictures as a circle, so the square corners of any photo you upload get cropped away. When you pick the Profile picture (400×400) preset, a 'Show safe zone' button appears over the preview — turning it on dims the four corners LinkedIn will cut and outlines the circle it will actually show, so you can confirm your face or logo stays fully inside before downloading. Toggle it off any time to see the untouched square image.

Select the Profile picture preset, keep Fit set to Cover so the photo fills the circular frame without empty space, then switch on the safe zone overlay to see exactly which corners LinkedIn will cut away. Reposition or re-crop your source photo so your face sits inside the dashed circle before downloading — this catches the classic 'top of head cut off' mistake before it goes live on your profile.
