What Thumbnail Maker AI does
Describe it, get thumbnails
Write what your video is about, in any language, and tap Generate. You get thumbnail options to pick from.
Prompt enhancer
Have a rough idea? The enhancer turns it into a fuller prompt, and you can preview the result before you generate.
Your face in the thumbnail
Add reference photos and save your faces as avatars, so your channel looks like you every time.
Viral score and audit
Get a score with a breakdown of what helps, plus a plain-language critique of a thumbnail you already have.
Crop and filters
Crop to the right shape, zoom in, and try 7 colour filters such as Vivid, Cool, Warm and Drama. Then save it to your gallery.
Titles, descriptions, hashtags
Draft a video title, a description and hashtags in the same app, and connect your channel to see which videos need a new thumbnail.

Questions
Is Thumbnail Maker AI free?
It is free to download. Generating thumbnails uses credits, and a Pro membership adds things like no ads, no watermark and a higher-quality model.
Do I need to sign up?
No. The app signs you in anonymously when you open it, so you can start without an email or password.
What size are the thumbnails?
Use 16:9, at least 640 px wide, as a JPG or PNG. Uploads from a phone must be under 2 MB, so 1280x720 under 2 MB is the safe choice. Use the free size checker on this site to test any image, and the crop editor in the app to fit one.
Can I use my own face?
Yes. Add reference photos, or save a face as an avatar to reuse in later thumbnails.
Does it work for Shorts and podcasts?
You describe the video, so it works for any kind of channel: gaming, vlogs, education, podcasts and more.
Does it work on Android and iPhone?
Yes, both. It is free to download from Google Play and the App Store.
