Been using Canva but the text always looked too small on my phone. This has fonts that actually work at thumbnail size. Finally my thumbnails are readable.

I just needed to add text to my thumbnails without paying $13/month. This does exactly that. Free tier covers like 10 thumbnails a month. Perfect for small channels.

The effects are stupid easy to use. Click outline, boom it has an outline. Click shadow, boom it pops off the background. Takes me 2 minutes to add text now.

Used to use Photoshop for text. Way too slow. This has the same effects but you just click instead of messing with layers. Saves me like 20 minutes per thumbnail.

Best Practices
Tips for Making Great Thumbnails
Keep it to 3-5 words maximum. More text means smaller font size which means nobody can read it on mobile. Your thumbnail is a teaser, not a paragraph.
Use high contrast always. White text with black outline works on any background. Low contrast text disappears on busy images.
Go bigger than feels right. Text that looks huge in the editor looks normal in the YouTube feed. Make it uncomfortably large.
Add shadows or outlines to every text layer. Plain text without effects disappears on complex backgrounds. Effects make words pop.
Test at mobile size before exporting. If you have to squint or zoom to read it, viewers will scroll past it. Check the preview.
Common Mistakes
What to Avoid
Using thin or decorative fonts. They look cool on desktop but turn into unreadable blurs on mobile. Stick to bold sans-serif fonts.
Writing full sentences on the thumbnail. Your title already has the sentence. Thumbnail text should be 3-5 words max that create curiosity.
Matching text color to the background. You want contrast, not color coordination. Make the text stand out, not blend in.
Skipping the mobile preview. Desktop view lies to you. Always check what your text looks like at small sizes before exporting.
Placing text over important parts of the image. If you're covering someone's face or the main subject, move the text to empty space.
