❓ Frequently Asked Questions

X (Twitter) Image Sizing FAQs

For standard feed images, 1600 × 900 px (16:9) or 1200 × 675 px are optimal for full horizontal visibility without cropping. For profile header banners, use 1500 × 500 px (3:1 ratio). For profile avatars, upload 400 × 400 px.

X automatically crops images that exceed standard aspect ratios between 4:5 and 16:9 in timeline previews. X also applies lossy compression to large images. Pre-sizing your image to 1600 × 900 px or 1080 × 1080 px in sRGB color format guarantees crisp 100% display without cropping.

On X profile banners (1500 × 500 px), the profile avatar covers the bottom-left corner, and browser viewport resizing can trim up to 60px from the top and bottom. Keep all important text, slogans, and logos centered within the 1400 × 380 px middle safe area.

X supports image uploads up to 5MB on mobile devices and up to 15MB on web browsers. Our tool optimizes your files into high-speed WebP, PNG, or JPEG formats that load instantaneously on slow connections.
