截图美化器
Drop a screenshot, pick a gradient, download a polished image. Perfect for Twitter, LinkedIn, blog posts and pitch decks. No upload, no sign-up.
Drop a screenshot here, click to browse, or Ctrl/Cmd + V to paste
PNG, JPG, WebP — anything your browser can decode
Make screenshots look like a designer made them
Plain screenshots feel raw and unfinished. Add a gradient background, a soft drop shadow, rounded corners and some breathing room, and the same screenshot becomes ready for a tweet, a blog header, a product launch page, or a pitch deck. That's all this tool does — but it does it instantly, in your browser, with no watermark and no sign-up.
三种导入图片的方式
- Click and pick. The drop zone opens a file picker.
- Drag and drop. Drop any image file directly on the page.
- Paste from clipboard. Take a screenshot (Cmd+Shift+4 on Mac, Win+Shift+S on Windows) and just press Ctrl/Cmd + V here. We catch the paste event and load the image.
可以调整的内容
- Background. Eight curated gradients (Sunset, Ocean, Forest, Fire, Night, Candy, Mint, Graphite), pure white, transparent, or any custom solid color from the color picker.
- Padding. 0 to 200 px of empty space around the screenshot.
- Corner radius. Round the screenshot itself for a softer look — 0 to 32 px.
- Shadow. None, Soft (subtle and tasteful) or Dramatic (deep, modern, dark-mode-friendly).
- Aspect ratio. Auto (just adds padding), 16:9 (YouTube / blog headers), 4:3 (classic decks), 1:1 (Instagram), 9:16 (Stories, TikTok). The screenshot stays centered; we add extra background to fill.
输出
Always PNG, to preserve transparency when selected and avoid JPEG artifacts on flat-color gradients. Download always works. Copy to clipboard works on modern Chromium, Edge and Firefox; Safari requires user gesture timing that sometimes fails. If copy fails, just download.
隐私
Every step happens locally with the Canvas API. We don't upload, we don't fingerprint, we don't ship analytics. No external image library either — the rendering is hand-rolled, which keeps the page lightweight and predictable.
常见使用场景
- Product launch tweets — a single hero image with the new feature behind a gradient.
- Documentation hero — wrap a UI screenshot with consistent branding.
- Blog post headers — match the post's mood with a color and shadow combo.
- Pitch decks — turn raw app captures into polished slides without leaving the browser.
- Tutorial threads — frame each step the same way for visual consistency.
