Fortnite Thumbnail Preview Tool

qptr.io is a free Fortnite thumbnail previewer. Upload your island thumbnail, type in your island name, and see exactly how it renders on the Fortnite Discover page — sitting in a six-tile row next to realistic neighbouring islands — before you publish. No sign-up, no download, no watermark: everything runs instantly in your browser.

Why preview before you publish

Epic gives you a real A/B test once your island is live: two thumbnails, a 50/50 traffic split, up to 90 days of click data. That is the right tool for settling a close call — and a slow, expensive one for discovering that your text is unreadable at tile size. qptr.io is the step before it. Drop each candidate into the Discover page, look at it next to its neighbours, and throw out the ones that disappear. Spend your live test slot on the two that survive.

How to preview a Fortnite thumbnail

1. Upload your 16:9 island thumbnail (1920×1080 or larger, JPG, under 5 MB).
2. Enter your island’s name.
3. See it rendered in place on a simulated Discover page, next to realistic neighbouring islands.
4. Reshuffle the neighbours and compare candidates until yours is the one your eye lands on first.

Frequently asked questions

What size is a Fortnite island thumbnail?

Fortnite Discover thumbnails are 16:9, at least 1920×1080 pixels, uploaded as a JPG under 5 MB. The old square 1024×1024 tiles were fully retired in June 2025, so design for 16:9 only. Full guide: Fortnite thumbnail size

How do I preview a Fortnite thumbnail before publishing?

Upload your thumbnail to qptr.io and type your island's name. The tool renders it on a simulated Fortnite Discover page, surrounded by realistic neighbouring islands, so you can judge how it reads in a 6-tile row before you publish anything.

Isn't Epic's built-in A/B test enough?

Epic's A/B test runs after you publish: two thumbnails, a 50/50 split, up to 90 days of real click data. It's the right way to settle a close call between two strong candidates. qptr.io covers the step before that — turning ten rough ideas into two strong candidates in a few minutes, without spending a live test slot on art you could have rejected on sight.

Does qptr.io store or upload my images?

No. Everything runs client-side in your browser. Your thumbnail never leaves your device — it's held only as a temporary in-browser preview.

Is the Fortnite previewer free?

Yes — completely free. No account, no download, no watermark. Upload a thumbnail and preview it instantly.
