X (formerly Twitter) displays single-image posts as 16:9 crops in the feed. While X accepts up to 4096px wide, anything above 1600 wide is downsampled and re-encoded with mediocre quality.
Resizing to exactly 1600×900 before upload gives you the maximum visual quality X will show, with no surprise cropping. ImageMint handles the resize locally in your browser.

FAQ
Does X support PNG?
Yes, but X re-encodes PNG to JPEG for photos. Use PNG only for graphics with text or sharp edges.
What's the max file size on X?
5MB for photos, 15MB for GIFs, 512MB for videos.
Why does X blur my images?
X downsamples anything larger than 1600px wide. Pre-resizing avoids the worst of it.
