What is this image size generator?
Upload one image and generate website favicon files plus ready-to-post social media assets in one browser-only workflow. The tool exports classic favicon sizes from 16x16 to 1024x1024, favicon.ico, Apple and Android icon files, Instagram post/story/reel cover, Facebook post/cover, YouTube thumbnail/banner, TikTok cover, LinkedIn post/banner, and X/Twitter post/header. Smart focal point cropping estimates the main subject and keeps it framed when aspect ratios change.
How to use
- Choose one PNG, JPG, WebP, or SVG-compatible browser image.
- Review the planned favicon and social media sizes before or after upload.
- After conversion, download a single PNG or use Download ZIP to get every output, favicon.ico, and site.webmanifest.
- Use square or high-resolution images for best favicon sharpness, and images with safe central space for social covers and banners.
