Free AI Thumbnail Maker for YouTube

Describe your video, upload a reference image, or paste a YouTube link. Kollab opens a task where you can compare and refine distinct thumbnail directions instead of facing a blank canvas.

Choose a thumbnail direction that fits your content

Start with a tutorial, podcast, travel video, or product review, then replace it with your topic, people, and brand assets.

Refine the first concept into a publish-ready thumbnail

Compare different compositions and focal points, then adjust the headline, subject, colors, and channel style through conversation.

Compare distinct directions for the same topic

Review headline-led, presenter-led, and scene-led concepts together without deciding every detail in the first pass.

Frequently asked questions

Can I start the thumbnail maker for free?+

Yes. You can shape the request on this public page and continue in a Kollab task. Available models, credits, and export capabilities depend on your current workspace plan.

Can I make a thumbnail from a YouTube link?+

Yes. A valid YouTube URL and your thumbnail request are handed to the task together. Make sure you have permission to use the video and any related source material.

Can I upload my own face or product image?+

Yes. Add one JPG, PNG, or WebP reference and explain which person, product, brand color, or composition cue should be preserved.

What thumbnail ratio should I use?+

This page focuses on the landscape 16:9 format commonly used on YouTube. Confirm the final pixel dimensions and file size in the task for your publishing destination.

Can I create several versions to compare?+

Yes. Ask for face-led, product-led, text-led, or curiosity-led directions with meaningful differences so you can select or test them later.

Will the AI copy another creator’s thumbnail?+

Do not ask it to copy a specific creator. Use source material you are allowed to use and describe your channel, subject, and broad visual direction instead.
