Free AI thumbnail generator, 3 thumbnails, no card
Free AI Thumbnail Maker
This free AI thumbnail maker gives every new account 3 thumbnails, full size and without a watermark, with no card. Paste your video's link: the brief is written for you, and each thumbnail comes back with its words read back and checked at feed size.



Free here means 3 finished thumbnails, not a preview. ThumbnailMaker gives each new account 30 credits, which are 3 thumbnails, with no card. They are full size, carry no watermark, don't expire and work on everything the Starter plan does: a video's link, a sentence, Shorts covers, banners, 4K, uploads and the API. They are given once per person, and to at most 300 new accounts in 31 days. After them, plans start at $12 a month.
What's free, what takes a plan
Your 3 free thumbnails next to a paid plan, row for row. A plan's thumbnails are 10 credits each.

How the free thumbnails work
Step 1
Paste your video's link
Use the field at the top of this page and sign up with Google, Discord or an email. The link comes with you into Create. With an email, confirm the address first: the free thumbnails are added on your first dashboard page after that.
Step 2
Read the score and the brief
Your current thumbnail is graded the way the feed shows it, each problem with its fix. The brief proposes three angles, each with a scene, the words and a style. Neither uses a free thumbnail.
Step 3
Click Generate
Each image uses one free thumbnail. The words are read back and redrawn once if a letter is wrong, then checked at the 336 px the feed shows, with the duration-badge corner kept clear. A run that returns nothing gives the thumbnail back.
Step 4
Download, or correct it
The file is full size with no watermark. If one thing is off, type it under the image: a correction uses one free thumbnail and keeps the rest.

Made by the same generator
Real outputs, each from a one-sentence brief. A free thumbnail goes through the same model and the same checks as a paid one.






What isn't free
The 3 free thumbnails cover what Starter does. These stay with a plan.
A fourth thumbnail
After the 3, every thumbnail, correction and 4K image takes a plan, from $12 a month for about 40. There is no free plan and no trial.
Pro
Three to test
Three concepts for YouTube's own Test & Compare, made in one go. Starter gets one free pack.
Pro
Auto-Polish
One click that reviews a thumbnail at feed size and fixes its weakest point. Starter gets one free run.
Pro
Brand kits and Recreate
Your channel's look saved and applied, and a new thumbnail in the composition and colours of an image or a video you point to.
Studio
Batch
Thumbnails for up to ten videos in one run, with a brand kit for each channel.
More than 10 image calls a day
Without a plan, an account makes up to 10 image calls in 24 hours, retries and uploads included. That covers the 3 and their corrections.
