Learn how to resize images for social media platforms. Get the exact dimensions for Facebook, Instagram, Twitter, and LinkedIn — free browser-based tool.

Your Images Never Fit Social Media Size Requirements?

Facebook, Instagram, Twitter, LinkedIn, and TikTok all have specific image dimension requirements for profile pictures, cover photos, post images, and story content. Uploading images with wrong dimensions results in awkward cropping, stretching, or low resolution. You need a quick way to resize images to platform specifications without uploading your photos to a third-party service.

Common frustrations:

  • Each social platform has different image size requirements
  • Uploading wrong-sized images results in poor cropping quality
  • You do not want to upload personal photos to online resizers
  • Mobile photo editors lack precise pixel dimension controls

Frequently Asked Questions

What are the standard social media image sizes?
Facebook post: 1200x630px, Instagram square: 1080x1080px, Twitter header: 1500x500px, LinkedIn cover: 1584x396px, YouTube thumbnail: 1280x720px.
Will resizing affect image quality on social media?
Resizing to the platform's recommended dimensions gives the best quality. Most platforms compress images further, so starting with the right size minimizes additional quality loss.
Can I use the same image for different platforms?
Yes. Resize the original image to each platform's dimensions separately. Keep the original file and create platform-specific versions as needed.
Is my photo uploaded to a server?
No. Your photo is processed entirely in your browser. It never leaves your device and is never uploaded to any server.
