A walkthrough, end to end.
- 1
Drag a screenshot onto the canvas, paste from clipboard with ⌘V (Ctrl+V on Windows), or click upload — the editor opens with the image already framed.
- 2
Pick a preset to start, then dial in the look: backgrounds, window chrome (macOS / Browser / plain), padding, rounding, drop shadow, border, image filters, 3D tilt, and text overlays.
- 3
Set your canvas size — Twitter cards, Instagram squares, full-HD wallpapers, App Store screenshots — or punch in a custom width and height.
- 4
Export as PNG, JPEG or SVG at 1×, 2× or 3× pixel density, or copy directly to clipboard with ⌘⇧C.
What you can do with this.
Twitter / X screenshot mockup
Drop a UI screenshot, pick a 1600×900 canvas and a vivid gradient background — perfect for product launches and threads. Glare and 3D tilt give the post a premium feel without going to Photoshop.
Instagram and LinkedIn product posts
Use the 1080×1080 (square) or 1080×1350 (portrait) presets to make scroll-stopping product shots. Add a headline and a one-line subtitle as text overlays — exported PNGs upload at Retina quality.
App Store screenshots and marketing assets
Pick the macOS or browser window chrome, frame your app screenshot, and export at 2× / 3× scale. Pair with a colored background to differentiate the asset from competitor listings.
Hero images for landing pages
Drop a screenshot of your product, set a transparent background and export an SVG — then drop it directly into your marketing site for a sharp, scalable hero shot at any DPR.
Documentation and tutorial screenshots
Add an arrow + label as a text overlay to walk readers through a UI step-by-step. Browser chrome makes it instantly clear this is a web app screenshot, not a random crop.
Open-graph images for blog posts
1200×630 OG-card preset is built in. Drop a screenshot, add the article title as a text layer, and export — share previews go from plain to professional in under a minute.
Frequently asked.
No. Everything runs entirely in your browser using the Canvas API and the html-to-image library. Your screenshot never leaves your device.
PNG (default, transparent background), JPEG (smaller file, white background) and SVG (vector). Each can be exported at 1×, 2× or 3× scale.
Yes. Use the size dropdown to pick a phone or tablet preset, or enter your store's exact required dimensions. Export at 2× or 3× for retina-quality.
Snap Studio is desktop-only — the editor needs the screen real estate to expose every control. On phones you'll see a polite redirect.
No watermark, no signup, no premium tier. Use the output anywhere, including commercially.
Yes — the Text Overlays section lets you add any number of text layers with custom font, size, weight, alignment, color and shadow. Drag them around the canvas.
