About Image Ranker
Image Ranker is a lightweight tool that helps you rank images by directly comparing them against each other.
How it works
- Upload images from your device (nothing is uploaded anywhere).
- Choose a ranking method:
- Full Ranking — exact ordering via comparisons (more matchups).
- Elo System — faster, approximate ranking using ratings (fewer matchups).
- Pick which image is better (or tie).
- Export the final ranking as JSON or PNG.
Privacy
All images stay in your browser. No servers, no tracking, no uploads. Closing the tab clears everything.
Great for
- Tier lists and “favorites” rankings
- Design and UI comparisons
- Art/photography selection
- Any “which one is better?” decision
Frequently Asked Questions
What’s the difference between Full Ranking and Elo?
Full Ranking creates a consistent total order but typically needs more comparisons. Elo asks fewer questions and estimates a ranking by updating ratings after each matchup.
What does “K” mean in Elo?
K controls how fast ratings change. Higher K reacts faster but can be noisier. Lower K is steadier but needs more matches to settle.
Are my images uploaded anywhere?
No. Everything runs locally in your browser. The app never sends your images to a server.
What does “Tie / Equal” do?
A tie tells the system you consider both images equal for that matchup. In Full Ranking, ties keep both items without forcing a strict preference. In Elo, ties award half-points to both sides (0.5 / 0.5), adjusting ratings more gently.
Can I export the results?
Yes — use “Download Ranking (JSON)” for a data file, or “Download Ranking (PNG)” for a shareable image.
Why do I see the same image multiple times in Elo?
Elo improves by repeatedly sampling matchups. Seeing an item multiple times helps its rating become more accurate.
