tips & examples

Getting the best results

Three to five words

Thumbnails are often seen at phone size. A short, large headline that complements your title reads better than a full sentence.

Contrast first

Light text with a dark outline (or the reverse) stays readable on any photo. Use “Darken image” when the background is busy.

Keep the bottom-right clear

YouTube overlays the video length in the bottom-right corner, so avoid placing important text there.

Thumbnail Maker questions

Do I need to sign up or log in?

No. The thumbnail maker works without an account, and your images stay on your device.

What size is a YouTube thumbnail?

Use a 16:9 image at least 640 pixels wide, in JPG or PNG. 1280 × 720 is the long-standing standard and looks sharp on phones and laptops; YouTube now also accepts 4K (3840 × 2160) for big TV screens. Files can be up to 50 MB when you upload from a computer, but only 2 MB from the YouTube mobile app. This editor exports either size.

Is there a watermark?

No. Exports contain only your design.

Can I edit text after adding it?

Yes. Text stays editable until you export: select a layer to change its words, font, size, color, outline, shadow or position.

Which fonts can I use?

Anton, Bebas Neue, Montserrat, Oswald and Permanent Marker are included (all free, open-licensed fonts), plus Inter Tight and common system fonts. Impact depends on your operating system.

Why is my PNG over 2 MB, and does it matter?

Detailed photos produce large PNG files. It only matters if you set thumbnails from the YouTube mobile app, which caps them at 2 MB; YouTube Studio on a computer accepts up to 50 MB. If you upload from your phone, export as JPG instead. The editor warns you when a file is over 2 MB.
