3

Download

Export a JPG or PNG at 1280×720, square or story size.

Why use it

Any frame

Scrub through the video or pick from six automatic key frames.

Readable titles

Bar, block, outline and clean styles keep text legible over busy footage.

Right size

16:9 for YouTube, square for feeds, 9:16 for stories — or the source size.

Private

Your footage never leaves your device.

What makes a thumbnail work

A thumbnail has a fraction of a second to explain what a video is about. Use a clear frame, a face or a single focal point, and a title of three to six words. If the title repeats the video title word for word, it wastes the space.

Choosing the frame

Drag through the video and look for a moment with strong expression, motion or a clear subject. Avoid frames that are blurry or half-blinked. The six key frames are a quick way to see the range before you scrub.

Styles

Bar adds a dark gradient behind the text, which is the safest choice over busy footage. Block puts the text on a solid colored strip. Outline draws a dark edge around bold letters. Clean uses a soft shadow only, best for calm images.

Sizes

1280×720 (16:9) is the usual YouTube size. Square is better for feeds, and 9:16 for stories and vertical covers. Source keeps your original proportions. Keep important text away from the edges, because the platform puts its own labels and timestamps there.

PNG or JPG

JPG is smaller and usually enough for thumbnails; PNG is lossless and larger. Platforms often have file size limits, so check them before you upload.

FAQ

Frequently asked questions

Is the thumbnail generator free?
Yes — completely free, with no account and no watermarks. Part of Mokivo.
Is my video uploaded to a server?
No. The frame is drawn in your browser. Nothing is sent anywhere.
What size should a YouTube thumbnail be?
The common size is 1280×720 (16:9), which is the default here. Check the platform for its current file size limit before you upload.
Can I use an image instead of a video?
Yes. Drop a photo or screenshot and add the title on top.
Which video formats work?
Whatever your browser can play — usually MP4 and WebM. If a file will not play in a normal browser tab, it will not load here.
