Image sizes for every major platform, and how to use them

Why the exact size matters
Platforms crop and compress images that aren't the shape they expect. A photo that looks fine on your screen can lose a face or a headline when the feed trims it to fit. Uploading at the recommended size means you decide what's in the frame, not the platform.
Size also affects sharpness. An image smaller than the size you need gets enlarged and can look soft, so the resizer tells you when that happens.
Recommended image sizes by platform
Each size below comes from the platform's own help pages or ads guides, checked in October 2026.
- LinkedIn post image: 1200 × 627.
- LinkedIn Company Page cover: 1512 × 256.
- LinkedIn ads: 1200 × 628 landscape, 1200 × 1200 square, or 720 × 900 vertical.
- Instagram and Facebook feed post: 1440 × 1800 (4:5).
- Instagram and Facebook Story and Reels: 1440 × 2560 (9:16).
- Link preview image (og:image): 1200 × 630.
- X header: 1500 × 500.
- YouTube thumbnail: 3840 × 2160 recommended; any 16:9 size from 640 wide works.
- YouTube channel banner: 2560 × 1440 and 6 MB or smaller, with logos and text inside the center 1544 × 423.
- Pinterest pin: 1000 × 1500.
Crop to fill, or show the whole image
Crop to fill covers the whole frame and trims what doesn't fit. Drag the image to choose what stays, and zoom in to tighten the shot. It's the right choice for most photos.
Show whole image keeps everything and fills the leftover space with a blurred copy of your image or a color you pick. Use it for logos, screenshots, and charts, where cutting anything off would lose information.
JPG or PNG?
JPG makes smaller files and suits photos. PNG keeps text, logos, and screenshots crisp, and when you crop to fill, it keeps transparent areas transparent. YouTube thumbnails and channel banners are always saved as JPG, so they stay under YouTube's file size limits: 2 MB for thumbnails uploaded from the app, 6 MB for banners.
Frequently asked
Questions, answered.
What people ask before they use the Social media image resizer.
No. The resizer works entirely in your browser. Your image is opened, cropped, and saved on your device, and never sent to a server.
Making an image smaller keeps it sharp. Making it larger can't add detail, so an image smaller than the size you pick may look soft. The resizer warns you when your image or crop is enlarged more than 1.5 times.
YouTube recommends 3840 × 2160 and accepts any 16:9 image at least 640 pixels wide. The resizer saves the largest 16:9 size your image supports, up to 3840 × 2160, as a JPG under 2 MB so it uploads from the YouTube app too.
LinkedIn recommends 1200 × 627 for images in posts. For ads, it recommends 1200 × 628 for landscape, 1200 × 1200 for square, and 720 × 900 for vertical images.
For feed posts, use 1440 × 1800, a 4:5 portrait shape that fills more of the feed. Instagram shrinks feed photos wider than 1080 pixels to 1080, so a 1080 × 1350 image looks the same in a regular post. For Stories and Reels, use 1440 × 2560 (9:16).
JPG, PNG, WebP, and GIF files up to 50 MB. Other formats work if your browser can open them. For an animated GIF, the resizer uses the first frame.
