NDT Snap — Screenshot Pro

Precision screenshots for developers & creators: viewport, selection, element, full page + inline editor & watermark.

NDT Snap Pro is a focused, fast screenshot tool for product folks, QA, designers, and marketers. Core features: Capture modes - Viewport: Capture what you see. - Selection / Custom: Drag to capture any region — overlay auto-hides before export so it won’t appear in the result. - Full Page: Auto-scrolls and stitches the whole page. A smart heuristic temporarily hides common fixed/sticky headers and cookie banners during the capture. Smart tools - Auto-hide sticky/ads/cookie banners while capturing (heuristic + MutationObserver). - Restricted-page notice on chrome://, Web Store, DevTools, etc. (Chrome doesn’t allow screenshots there). Built-in editor - Format + Quality + Scale (1×/2×/3×) directly on the top bar next to Save. - Export PNG/JPEG/WEBP (filenames add @2x/@3x automatically when scaled). - Copy to Clipboard right from the editor. - Watermark support (presets retained from 0.4.x). - Responsive top bar that wraps neatly on smaller windows. Mini History - Slide-out Recent panel with the last 8 screenshots for quick access. Notes & limitations - Chrome blocks screenshots on internal pages like chrome://*, Web Store, DevTools, etc. NDT Snap Pro will show a friendly notice instead of failing. - Some sites use unusual overlays or animated sticky bars. The built-in heuristic hides most of them; edge cases may still show elements. What’s new (Change log) v0.5.0 Viewport: fixed non-responsive behavior by adding a dedicated background route (captureAndOpen). Selection/Custom: overlay no longer appears in captures (double-RAF + short delay before capture). Full Page: temporarily hides common fixed/sticky headers + cookie banners while stitching. Editor: Moved Format + Quality to the top bar, added Scale (1×/2×/3×). Responsive top bar; stability fixes in export (exportWithWM, Save/Copy). Popup: Slide-out Recent panel (1/2 popup width) without horizontal overflow; Ready status always visible. Clear notice on restricted pages instead of error. Accessibility: Added accessible labels for selection inputs; replaced decorative label with an aria-hidden span to satisfy Lighthouse. Stability: Rebuilt background service worker with proper async responses and a last-8 history. Contact Tony Nguyen Email: admin@ndtan.net Telegram: @nguyenduytan Website: https://nguyenduytan.com
