썸네일만들기 카드뉴스 - 블로그 디자인 섬네일메이커

썸네일만들기 카드뉴스 is an Android app that lets you create click-worthy YouTube thumbnails and scroll-through card news on your phone in about one minute. Simply edit the text on the pre-filled example screen, and you get a polished, eye-catching image even if you have no design experience.

The app supports five formats: YouTube thumbnails (16:9), card news (4:5, up to 10 pages), Instagram feeds (1:1), Shorts and Reels covers (9:16), and blog or cafe representative images (4:3). Wrap words in [brackets] to highlight them in an accent color, and add stickers such as "Great Tip", "Must Read", and "NEW". You can also use a frame from a video, or a photo from your gallery or camera, as the background, with four darkness levels to keep text readable. Choose from 8 design styles, including Bold Outline, Breaking News Banner, Gradient, and Dark Neon, plus 12 accent colors and various Korean fonts.

Manage multiple card news pages at once, save them all to your gallery, and share them together via Instagram or KakaoTalk. Your creations are stored in an archive for later editing, and Backup and Restore lets you move content to a new phone. Images are created on your device, and your photos and videos are never sent externally.
