321 Action - Professional Screenshots

Capture pixel-perfect screenshots at common social and web dimensions.

321 Action — Professional Screenshots The professional screenshot tool built into your browser. Exact pixel dimensions, multiple capture shapes, rotation, live resize controls, and every major platform size built in — everything you need to produce polished, publish-ready assets straight from the page. No design app. No resizing after the fact. Stop cropping after the shot. 321 Action puts a live, fully editable capture frame on top of any webpage. Pick your target size, shape the frame, and fire — the PNG lands in your Downloads folder at the exact pixel dimensions you need, ready to post. Position the frame, hit Action, and a cinematic 3·2·1 countdown fires the shot. The overlay disappears for a clean capture, then comes straight back if you need another. 📐 BUILT-IN PRESETS Every common social and web size, one click away: • Instagram — Square (1080×1080), Portrait (1080×1350), Story (1080×1920) • X / Twitter Post — 1600×900 • Facebook Post — 1200×630 • LinkedIn Post — 1200×627 • YouTube Thumbnail — 1280×720 • Open Graph Image — 1200×630 • Pinterest Pin — 1000×1500 • Wallpaper FHD — 1920×1080 🔷 SEVEN CAPTURE SHAPES Rectangle, Square, Circle, Ellipse, Triangle, Diamond, Hexagon. Switch between them live on the page — right from the bottom toolbar — without closing the overlay or reopening the popup. The dark mask and capture boundary update instantly. Rounded corners are available for every polygon shape. Toggle them on with one click and scrub the radius with a slider to see the effect in real time. Circle and ellipse outputs are mask-clipped with clean edges, perfect for avatars and profile photos. 🎛️ IN-CAPTURE CONTROLS The on-page frame is a full mini editor, no design app required: • Drag the frame anywhere to reposition. • Drag corner handles to resize freely; drag the center-of-edge pill handles to adjust a single dimension. • Hold ⌘ (Cmd) while dragging a corner to resize proportionally — aspect ratio stays locked. • Hold ⌥ (Option) while dragging a corner to resize symmetrically from the center — both sides move equally. • Drag the rotate handle above the frame to tilt the selection to any angle. The export is automatically de-rotated. • Switch shapes live from the toolbar at the bottom. • Toggle rounded corners and scrub the radius slider in real time. 📖 HOW IT WORKS 1. Click the 321 Action icon in your toolbar. 2. Pick a preset or enter custom dimensions and a shape. 3. An on-page frame appears. Drag it, resize it, rotate it, or change the shape — all without leaving the page. 4. Hit Action (or press Enter). A 3·2·1 countdown plays, the overlay disappears for a clean shot, and the screenshot is captured at full target resolution — no upscaling, no blur. 5. The PNG saves automatically to your Downloads folder, named with size and timestamp. Press Esc at any time to cancel. ✨ WHY IT'S DIFFERENT • Exact target dimensions, not "close enough." Upload directly without resizing in another tool. • DPI-aware. Works correctly on Retina and HiDPI displays — what you frame is what you get. • Seven shapes, switchable live. Change from rectangle to circle to triangle without reopening the popup. • Rotation with clean output. Tilt the frame, get a straight PNG — de-rotation runs on the captured bitmap. • Canva-style resize handles. ⌘ for proportional, ⌥ for symmetric from center, edge handles for single-axis. • Rounded corners, built in. Dial a radius on any polygon shape — no Photoshop round-trip needed. • Cinematic capture flow. The 3·2·1 countdown gives you a beat to clear hover states before the shot fires. • Zero friction. No login, no account, no cloud upload. Nothing to sign up for.
