Screenshot Mockup Generator — turn screenshots into device-frame mockups
The screenshot mockup generator drops your web or app screenshot into a clean device frame — iPhone, Android, a Mac laptop, or a browser window with an address bar — then sets it on a spotlit gradient or mesh background with a soft shadow, padding and an optional 3D tilt. Export a polished shot for your portfolio, Product Hunt, landing page or socials. Every frame is hand-drawn vector — pin-sharp at any size, with zero asset-licensing risk — and it's all composited locally in your browser. Your screenshot is never uploaded.
Screenshot Mockup Generator is a free online tool from MockCat that runs entirely in your browser — open it, do it, and download the result. Nothing is uploaded, there's no sign-up and no limits.

Device-frame vs photographic mockups: which one do you need?
"Mockups" really come in two flavors, and knowing the difference saves a lot of detours. The first is the "device / window frame" mockup: your web or app screenshot tucked into a clean iPhone, Android, Mac or browser frame with a background and shadow — the point is to be tidy, sharp and to show off the interface itself. It's what you want for portfolios, Product Hunt hero shots, landing-page heroes, docs and app intros. The second is the "real photographic scene" mockup: your design printed on a T-shirt, mug or storefront sign in an actual photo — here the point is the real-world vibe. MockCat's screenshot tool does the first kind: every frame is code-drawn, so it stays vector-sharp at any export size, depends on no image assets, and sidesteps the Apple Design Resources and Meta device rules that forbid repackaging their bezels as assets.
A few details make or break a usable device mockup: pick the right frame — a browser window with an address bar gives a website context, a phone frame suits mobile, a laptop suits desktop apps, and "plain" gives a clean crop; don't let the background shout — one coordinated gradient to lift the UI off dead white is plenty, with enough padding to breathe; keep the shadow soft for a gentle float rather than a hard black edge; and add a touch of 3D tilt if you want some depth. MockCat wires these into handy sliders and presets, so you drop the image, pick a frame, nudge a couple of controls and you're done — all composited locally, nothing uploaded.
When should you leave this tool? When you need the photo-real vibe of "the product in the real world" — a real model wearing your tee, a hand holding a printed mug, a poster on a café wall. Code frames can't do that; you need a dedicated photographic mockup library like Placeit, where you drag your design into a real photo. MockCat's lane is clear: for sharp, tidy interface and design previews, use us — free, local, vector-crisp; for real-world photographic vibes, use a dedicated library. They're complementary — make the lightweight version here, and upgrade when you need a whole litter of real scenes.
Screenshot mockup tools compared: MockCat vs Shotsnapp vs MockuPhone vs Placeit
Device mockups split into "free in-browser (interface display)" and "paid photographic (real world)". The table lists only verifiable facts (as of June 2026, per each vendor's site), without hype or knocking anyone; a one-line "which should you use" follows.
| Tool | Free | No login | Local (no upload) | Coverage |
|---|---|---|---|---|
| MockCat Screenshot Mockup | Yes | Yes | Yes (canvas, local) | iPhone/Android/Mac/browser + tee/mug/book/poster + App Store |
| Shotsnapp | Yes (device frames free) | Yes | Not stated | Device frames only, no apparel/print |
| MockuPhone | Yes | Yes | Not stated | Device bezel only, no background/text |
| Placeit | Preview only (download needs a sub) | Login required | Cloud | Thousands of photographic scenes |
"Not stated" means the vendor's site doesn't explicitly claim it, so we won't assert it. Placeit is a paid library for the photographic scenes code frames can't do.
Which should you use?
- Show a web / app interface cleanly (portfolio, landing page, docs): Use MockCat — free, local, vector-crisp frames, plus transparent export.
- Just want a phone bezel, no background: MockuPhone works, but MockCat is also free and adds backgrounds/shadows.
- Want "the product in the real world" (a model in your tee, a storefront): Code frames can't do it — use a photographic library like Placeit.
How to use screenshot mockup generator
- 1Drop or paste (Ctrl/⌘+V) a screenshot — a webpage, app, or product shot.
- 2Pick a frame: iPhone (dynamic island), Android, Mac laptop, browser window, or plain.
- 3Choose a background, then dial in padding, corner radius, shadow and a slight 3D tilt.
- 4Export at 1×/2× or with a transparent background — download or copy straight to clipboard.
Why use MockCat's Screenshot Mockup Generator?
- Hand-drawn vector frames: iPhone / Android / Mac / browser are all code-drawn — crisp at any scale, and free of Apple/Meta bezel licensing risk.
- Local compositing: your screenshot is never uploaded — screenshots often contain code, dashboards and chats that shouldn't leave your device.
- Transparent export: export a cut-out PNG to drop into slides, docs or a bigger scene.
- Ready to post: built-in 2× export and clipboard copy — paste straight into a tweet, doc or landing page.
Frequently asked questions
Which device frames are supported?
iPhone (modern flat edge + dynamic island), Android (generic flat frame), Mac laptop, a macOS/browser window (traffic-light dots + address bar), and plain (background/shadow only, no frame). All frames are hand-drawn vector, crisp at any scale.
Why not use Apple's official iPhone bezel?
Apple Design Resources' device bezels are licensed only for UI mockups of software that runs on Apple platforms, and may not be extracted, modified or repackaged as assets — using them to make sellable mockups violates the terms. Meta's device assets likewise can't be repackaged. MockCat draws everything as a generic shape, so there's zero licensing risk — which matters when you'll take the output to a store or sell it.
Can I export a transparent background?
Yes. Choose "transparent background" to export a cut-out PNG (device frame + screenshot, no background) for compositing into slides, docs or bigger scenes.
Is my screenshot uploaded?
No. Everything is composited locally with canvas; your screenshot never leaves your device — screenshots often contain code, dashboards, chats and errors that shouldn't go to a stranger's server.
How does it compare to Shotsnapp / Pika?
Same idea — backgrounds, padding, shadow, device frames. Shotsnapp focuses on device frames; Pika is dev-leaning and subscription. MockCat is broader — beyond device frames it does App Store screenshots and T-shirt / mug / book / poster mockups — and it's bilingual, local and free with no watermark.
