What size should my Instagram post image be?
Square posts perform best at 1080×1080 px. Portrait posts (slightly taller) use 1080×1350 px, and landscape posts use 1080×566 px. For Stories and Reels, use 1080×1920 px.
What is the correct Twitter/X image size?
In-stream tweet images display at 1200×675 px (16:9 ratio). Profile headers are 1500×500 px. Profile photos are cropped to a circle, so keep important elements centered.
What LinkedIn image dimensions should I use?
Post images: 1200×627 px. Company page cover: 1584×396 px. Personal profile cover: 1584×396 px. Post thumbnails and article covers: 1200×627 px.
Does resizing happen in my browser?
Yes. All processing uses the browser's Canvas API. Your image is never uploaded to any server — it stays entirely on your device, making it safe for sensitive or personal photos.
Will quality be lost when resizing?
Downscaling from a high-resolution original produces minimal quality loss. The tool uses bilinear interpolation via the Canvas API. For best results, always start from the highest resolution source you have.
Can I use these social media tools on mobile?
Yes. Every tool runs directly in your mobile browser — no app download needed. Upload your image from your camera roll and download the resized result instantly.
Social Media Image Size Guide
Instagram & Facebook
Instagram posts perform best at 1080×1080 px (square) or 1080×1350 px (portrait). Stories and Reels should be 1080×1920 px. Facebook post images are ideal at 1200×630 px for link shares.
Always export at the highest resolution you have — both platforms will downsample automatically, but starting too small results in visible compression artifacts.
Twitter/X & LinkedIn
Twitter/X in-stream images display at 1200×675 px (16:9). Header banners are 1500×500 px. LinkedIn post images work best at 1200×627 px, and cover photos at 1584×396 px.
Keeping text and logos away from the edges avoids cropping on mobile, where platforms apply tighter safe zones.
Pinterest & YouTube
Pinterest Pins perform best in portrait orientation at 1000×1500 px (2:3). Taller Pins (1:2.1) are allowed but can be clipped in some views.
YouTube thumbnails should be 1280×720 px (16:9) at a minimum. Channel art renders across devices at 2560×1440 px — keep critical content in the central 1546×423 px safe zone.
