Social Media Image Resizer

Upload any image and resize it to the exact pixel dimensions required by major social media platforms. Includes presets for Instagram (post 1080×1080, story 1080×1920, landscape 1080×566), Facebook (post 1200×630, cover 820×312), X/Twitter (post 1200×675, header 1500×500), LinkedIn (post 1200×627, cover 1584×396), YouTube thumbnails (1280×720), TikTok (1080×1920), and Pinterest pins (1000×1500).

The resizer uses a center-crop strategy: the image is scaled to completely fill the target dimensions, then excess is cropped equally from the edges. This ensures no letterboxing or distortion — the output is always the exact size the platform requires.

Custom dimensions are supported if your platform or use case is not in the presets. Upload JPEG, PNG, or WebP files. The output is always a PNG. All processing uses the HTML5 Canvas API entirely in your browser — images are never uploaded to any server.

Every social media platform has specific image dimension requirements, and uploading images that do not match these requirements results in unexpected cropping, blurriness, or compression artifacts. This tool eliminates those issues by producing pixel-perfect output for every platform.

Instagram has three main image formats: square posts (1080×1080, 1:1 ratio), portrait posts (1080×1350, 4:5 ratio), and landscape posts (1080×566, 1.91:1 ratio). Instagram Stories and Reels both use 1080×1920 (9:16). The platform compresses images larger than these dimensions, so uploading at exactly the recommended size gives you the best quality.

Facebook supports several image types. Link preview images and shared posts use 1200×630 (1.91:1), which is the same ratio as Open Graph images. Facebook cover photos are 820×312 on desktop but are cropped differently on mobile, so keep important content centered and away from the edges. Facebook event images use 1920×1080 (16:9).

X/Twitter post images display at 1200×675 (16:9) in the timeline. Header images are 1500×500 (3:1) but are cropped on mobile, so design with safe zones. Twitter card images for shared links use 1200×628 for summary cards with large images.

LinkedIn post images use 1200×627 (approximately 1.91:1). LinkedIn cover photos (the banner at the top of a personal or company page) are 1584×396 (4:1). LinkedIn article banners use 1280×720 (16:9).

YouTube thumbnails are always 1280×720 (16:9). Custom thumbnails are one of the most important factors in click-through rate, so creating a properly sized, visually compelling thumbnail is worth the effort. YouTube channel banners are 2560×1440 but display differently across devices.

TikTok videos and profile photos both use the vertical 1080×1920 (9:16) format. Pinterest pins perform best at 1000×1500 (2:3), which is taller than most other social media formats and optimized for the Pinterest grid layout.

Tips for best results: Start with the highest resolution source image you have. The center-crop algorithm preserves the most detail from your original. Avoid uploading screenshots or already-compressed images as source material, as each platform applies its own compression on top of whatever quality you provide.
