Turn your stream clip into a thumbnail that gets clicked
Grab the frame from your Twitch or gameplay clip, drop a bold headline, and the contrast scrim + image punch handle the rest. High-CTR thumbnails for your clips on YouTube, Twitch and Shorts — in seconds.
This free clip thumbnail maker is built for streamers: turn a frame from your Twitch or gameplay clip into a thumbnail that actually gets clicked. Grab the clutch, the reaction, the rage moment, add a short bold headline, and the tool layers an automatic contrast scrim and an image punch (brightness, contrast, saturation) so your text stays readable and the gameplay pops — the two things that move click-through. Export at 1280×720 for YouTube and Twitch clips, or 1:1 and 9:16 for Shorts. No login, nothing uploaded.

What makes a gaming thumbnail get clicked
Three things, in order: a readable headline (2–4 big words you can read on a phone), high contrast so your gameplay and text pop against everything else in the feed, and a clear moment — a clutch, a multi-kill, a reaction face, a rage quit. This tool bakes the first two in: text gets a heavy stroke and an automatic dark scrim, and the image punch boosts contrast and saturation so the frame never looks flat. Keep the words short and the action big and you're most of the way there.
Sizes for every platform you post to
1280×720 (16:9) is the standard for YouTube and Twitch clips. 1:1 suits some social posts, and 9:16 works as a cover for Shorts, Reels and TikTok. Export the one your platform needs — the layout and text scale to each.
Where the best clips come from
The best thumbnails start with the best moments — and as a streamer, those are buried in hours of VOD. Eklipse's AI clips your streams automatically, so you always have fresh, high-emotion frames to turn into thumbnails — and ready-to-post Shorts while you're at it.

How do I make a thumbnail from a clip?
Upload the clip (or paste a Twitch clip link), scrub to the best frame, add a short bold headline, then export. The tool auto-adds a contrast scrim and image punch so it reads well at small sizes. Export at 1280×720, 1:1 or 9:16.
What size should a thumbnail be?
1280×720 (16:9) is standard for YouTube and Twitch. For Shorts, Reels and TikTok covers use 9:16. The tool exports all three.
Is it free? Any watermark?
It's 100% free, needs no account, and adds no watermark. Everything is generated in your browser — nothing is uploaded.
Can I use a YouTube or Twitch link?
Twitch clip links work. YouTube, Reels and TikTok can't be read by a browser, so download the clip first with our VOD Downloader and upload it — or generate an AI background instead.
How do I write a high-CTR headline?
Keep it to 2–4 big words that create curiosity or emotion ("INSANE", "1V5?!", "HOW?!"). Hit Suggest for ideas. Shorter and bolder almost always beats a full sentence at thumbnail scale.
