Will people click your thumbnail?
Check a YouTube thumbnail, a Shorts or Reels cover, or an Instagram post the way a designer would. See it at real phone size, find text that is too small or hard to read, things hidden under YouTube's buttons, dark or blurry spots and clutter. Then fix it in one click and compare before and after. The checks run in your browser.
How it looks on a phone
This is the real size people see it at, next to other videos. If you can't read it here, they can't either.

A designer's opinion (AI)
An AI looks at the picture like a thumbnail designer: the idea, the emotion, the story, Urdu and Hindi text, and what to change. Your thumbnail is sent to the AI for this step only.
- Size and shape: 1280×720 for YouTube, 1080×1920 for Shorts and Reels, 1080×1350 for Instagram, and the 2 MB YouTube limit.
- Phone-size text: every word is measured at the size YouTube shows suggested videos (168 pixels wide).
- Text readability: the contrast between each word and what is behind it.
- Hidden areas: YouTube's video length badge, the Shorts and Reels buttons and title, and Instagram's profile grid crop.
- Faces: whether there is a face and whether it is big enough to see on a phone.
- Light, contrast, colour, sharpness and clutter, measured on the pixels.
Is this free?
Yes. The checks and the fixes run in your browser for free. You only sign in with a free account to download the fixed picture.
Does a better score mean more views?
Not by itself. A clear, readable thumbnail helps people understand and click your video, but the title, the topic and the video itself matter too. Use the score as a designer's checklist, not a promise.
Can it read Urdu and Hindi text?
The quick checks read English letters. For Urdu and Hindi text, press "Ask the AI designer", which looks at the whole picture.
