LinkedIn バナーの画像のサイズを変更する
LinkedIn banner images must be exactly 1584×396 pixels. Upload an image with the wrong size and LinkedIn crops it automatically — often cutting off your headline, logo, or key visual.

Your LinkedIn banner is the first thing visitors see on your profile. A poorly cropped banner looks unprofessional and damages your personal brand. The exact requirement is 1584 pixels wide by 396 pixels tall, in JPG, PNG, or GIF format. Our Image Resizer has a built-in LinkedIn preset that crops and resizes your photo to these exact dimensions. Everything processes locally in your browser — your professional headshots and brand visuals never leave your device.
仕組み
1. Upload your photo — any size, any format (JPG, PNG, WebP).
2. Select the LinkedIn Banner preset — automatic resize to 1584×396.
3. Download and upload to LinkedIn — perfectly sized, no awkward cropping.
オンラインで共有する前に画像を最適化する理由は何ですか?
High-resolution photos from modern smartphones can easily exceed 5-10 MB per image. These large files slow down email delivery, exceed social media upload limits, and consume excessive bandwidth. Our image optimization tools compress, resize, and convert your photos directly in the browser.
Image files also contain EXIF metadata including GPS coordinates, camera model, and timestamps. Our tools strip this sensitive information while preserving image quality, ensuring your privacy when sharing photos online.
サポートされている画像形式
We support all major image formats: JPG, JPEG, PNG, WebP, HEIC, and TIFF. Whether you need to compress photos for email, resize images for social media, convert HEIC to JPG for Windows compatibility, or embed images as Base64 in HTML — everything happens locally in your browser.

画質に影響はありますか?
Our compression algorithms use intelligent quality optimization. You can choose between lossy compression (smaller files, minimal quality loss) for web sharing, or lossless compression (preserves 100% quality) for archival purposes. The choice is yours, and everything stays private.
