Upload one image or a whole batch, and AlienSync's AI intelligently sequences, crops, and enhances your images into a smooth, optimized animated GIF — or adds subtle AI-generated motion to a single still photo.
Drop in any video and let AlienSync find the best moment automatically, or trim it yourself. Our AI handles frame sampling, color optimization, and compression so your GIF looks sharp at a fraction of the file size.
Both AlienSync tools follow the same simple flow — built to be fast enough for a quick social post and precise enough for a professional campaign.
Drag and drop an image, image set, or video — or paste a link. Files stay private and are processed securely.
AlienSync analyzes your content, selects the best frames, and optimizes color and size automatically.
Preview your GIF, fine-tune it if needed, then export and share directly to social, Slack, or email.
AlienSync is built specifically for GIF conversion — so every feature exists to make your GIFs faster, smaller, and better looking.
Most conversions finish in under 10 seconds, even for larger videos and multi-image batches.
AI-driven color palette reduction cuts file size by up to 98% without visible quality loss.
AlienSync detects the subject and frames it automatically, so you rarely need to crop by hand.
Convert dozens of images or several clips in one pass on Pro and Business plans.
Automate conversions from your own app or workflow with the AlienSync REST API.
Uploaded files are encrypted in transit and automatically deleted from our servers after processing.

"The AI auto-crop on the image tool is scary good. It picks the right frame almost every time without me touching anything."
"File sizes are dramatically smaller than any converter we tried before, and the quality still holds up on retina screens."
Start free. Upgrade only when you need batch processing, HD exports, or API access.
