What size is a Twitter/X Header image?

The recommended export size is 1500 × 500 px. This tool targets those pixels automatically when you upload a photo.

Is my image uploaded to ShoutingNow servers?

No. Seam carving runs in your browser with WebAssembly. Your file never leaves your device.

Can I resize to other social formats from the same photo?

Yes. Use batch export on this page for related sizes, or open the main Content-Aware Scale tool to pick any platform preset.

Should I use Fill Frame or Smart Crop?

The tool picks the correct mode from your source and target dimensions. Fill Frame adds space; Smart Crop removes low-energy pixels when your source is already larger than the target frame.

Does face protection work on this preset?

Yes. Face detection is enabled by default so detected faces are pinned during seam carving — especially important for profile banners and thumbnails with people.

Which file format should I download?

Use JPEG for photos and smaller file sizes. Choose PNG when you need crisp text or logos. WebP offers a modern balance of quality and compression.

Twitter/X headers display at 1500×500 pixels (3:1) — one of the widest social formats. Content-aware fill extends horizontal background instead of zooming out your subject.

Batch export post (1200×675) and avatar (400×400) sizes after your header preview is ready. Center important visuals — the profile avatar overlaps the bottom-left on desktop.
