A tiny studio for big hooks

No watermarks. No uploads. No design skills needed. Just the tools Shorts creators actually use.

Text that pops

Bold display fonts, thick outlines, glows and shadows — the exact style that survives the Shorts feed at 200px tall.

Image filters

Brightness, contrast, saturation, blur and grayscale. Darken photos so your text always wins the contrast war.

Niche templates

Fifteen ready-made layouts for gaming, finance, tech, fitness, podcasts, reaction, cooking, horror and more. One tap to apply.

Shapes & emojis

Arrows, badges, stars, YouTube-style icons, sketch doodles and 60+ emojis to point, highlight and hype up your hook.

Shorts safe-zone guides

See exactly where YouTube overlays its UI. Keep your title readable and your CTA out of the caption zone.

True 1080×1920 export

PNG or JPEG rendered at full resolution in your browser — plus one-tap clipboard copy straight into YouTube Studio.

Templates for your niche

Every preview below is live and clickable — tap one and it opens ready-to-edit.

Hook-ready in three moves

01

Pick a template

Choose your niche or start from a blank vertical canvas. Templates come pre-loaded with layout, fonts and colors.

02

Make it yours

Drop in your photo, rewrite the hook, crank the outline. Safe-zone guides keep text clear of YouTube's UI.

03

Export & upload

Download a crisp 1080×1920 PNG or copy it to your clipboard and paste it straight into YouTube Studio.

Frequently asked

Is ShortThumbs really free?

Yes. The free plan covers the full editor and unlimited 1080p exports — no watermark, no trial clock. An optional Pro upgrade adds 2K/4K export and premium effects.

Do my images get uploaded anywhere?

No. Everything is processed on your device — your photos never leave your computer. Close the tab and nothing remains except an autosave in your own browser storage.

What size should a YouTube Shorts thumbnail be?

Shorts use a vertical 9:16 frame, so we design and export at 1080×1920 — the same resolution as your video.

How do I set the thumbnail on my Short?

Export your design as a PNG, then upload it in YouTube Studio. You can also copy it to your clipboard and paste it directly where YouTube asks for the image.

Will my work survive a refresh?

Yes — every change autosaves locally. Come back later (same browser) and your draft will be waiting on the editor page.
