Looping GIF From Static Image

I have a single high-resolution photo that I’d like transformed into an eye-catching, endlessly looping GIF for a social media post. The animation should focus solely on bringing the main subject to life while the background remains static. Think subtle motion—parallax, a gentle sway, or another smooth effect that cycles seamlessly without a visible start or end.

Deliverables
• Optimised GIF: 1080×1080 px (or original aspect ratio), <3 MB, ready for Instagram, Facebook, and X
• Two loop lengths to test: roughly 3 s and 5 s
• Source file from your chosen tool (Photoshop timeline, After Effects, or similar) so future tweaks are straightforward

No extra text, overlays, or background effects—just a clean loop that makes viewers stop scrolling. Let me know which software you prefer and any details you need before getting started so we can move quickly.
