Image Editing for Social Media: Resize, Crop, and Optimize for Every Platform

Every social media platform has different image requirements. Instagram wants square 1080×1080 images for posts and 1080×1920 for stories. LinkedIn prefers 1200×627 for shared images. Twitter crops differently on mobile and desktop. If you upload the wrong size, your images get cropped, stretched, or pixelated. This guide covers the exact dimensions for every major platform, plus the tools and workflows to resize, crop, and optimize images for social media.

By the end, you'll have a complete reference for social media image sizes and a workflow for preparing any image for any platform.

Instagram image sizes

Instagram has the most specific image requirements of any platform. Getting the size right means your image displays fully without cropping.

• Square posts — 1080×1080 pixels. The classic Instagram format.
• Portrait posts — 1080×1350 pixels. Takes up more screen space, gets more engagement.
• Landscape posts — 1080×566 pixels. Good for wide photos.
• Stories — 1080×1920 pixels. Full vertical 9:16 aspect ratio.
• Reels cover — 1080×1920 pixels. Same as stories.
• Profile photo — 320×320 pixels. Displays as a circle.
• Highlights cover — 1080×1920 pixels. Same as stories.

LinkedIn image sizes

LinkedIn images should be professional and high-quality. The platform favors larger images that take up more of the feed.

• Shared image post — 1200×627 pixels. The standard LinkedIn post image.
• LinkedIn article thumbnail — 1280×720 pixels. 16:9 aspect ratio.
• Cover photo — 1584×396 pixels. The banner at the top of your profile.
• Company logo — 300×300 pixels. Displays as a square.
• Life at company tab — 1128×376 pixels. For company page culture section.

Facebook image sizes

Facebook has different sizes for personal profiles, business pages, and ads.

How to resize images for social media

Resizing images for social media is about more than just changing dimensions. You need to consider aspect ratio, cropping, and quality.

The workflow:

• Start with the original high-resolution image — never resize from an already-compressed image.
• Determine the target dimensions for your platform.
• Crop to the correct aspect ratio first — this ensures the important content stays in frame.
• Resize to the exact pixel dimensions — this ensures the image displays at full quality.
• Compress to optimize file size — aim for under 300 KB for fast loading.
• Export in the right format — JPG for photos, PNG for graphics with text.

Cropping for different aspect ratios

Different platforms use different aspect ratios. A photo that looks great as a landscape image on Facebook might need to be cropped to a square for Instagram. The key is to crop intentionally, not let the platform crop automatically.

When cropping:

• Keep the subject in the center — platforms crop from the edges, so center content is preserved.
• Check the crop on mobile — most users view on phones, where cropping can be more aggressive.
• Avoid text near the edges — it may get cut off on different devices.
• Create multiple crops — one image can be cropped differently for each platform.

Batch processing for efficiency

If you're preparing multiple images for social media, batch processing saves significant time. Instead of resizing each image individually, process them all at once with the same settings.

For batch processing, create a folder with all your original images, set the target dimensions and quality, and process them all in one operation. This is especially useful for product photos, event coverage, or content series where all images need the same dimensions.

Optimizing for mobile

Most social media is viewed on mobile, where data and load times matter. Optimize your images for mobile by:

• Keeping file sizes under 300 KB — mobile users on data plans will thank you.
• Using the correct dimensions — don't make mobile users download a 4000px image displayed at 400px.
• Testing on a real phone — images look different on small screens.
• Considering portrait orientation — it takes up more screen space on mobile.

The bottom line

Every social platform has specific image requirements, and getting them right means your images display perfectly. Always start with a high-resolution original, crop to the correct aspect ratio, resize to the exact dimensions, and compress for fast loading. Create multiple crops from one image for different platforms, and always test on mobile. The tools on this page handle every aspect of social media image preparation — from resizing to cropping to batch processing.
