Screenshot Mockup Generator

About / How to Use

The Screenshot Mockup Generator wraps a plain screenshot in a presentation-ready frame directly in your browser using the Canvas API. Upload an image, then adjust the controls on the left and watch the live preview update instantly.

• Frame style — choose "Browser Window" to draw a rounded chrome bar above your screenshot with three small traffic-light circles and a pill-shaped fake address bar, making it instantly read as "a website." Choose "None" to skip the chrome bar entirely and just apply the background, padding, radius, and shadow around the raw screenshot.
• Background — pick a flat solid color, or switch to a two-color linear gradient with an adjustable angle from 0–360°. If you want to explore color combinations before settling on one, the Color Gradient Generator is a good place to experiment with palettes first.
• Padding — controls how much background shows around the framed screenshot, from a tight 20px border up to a generous 160px of breathing room.
• Corner radius — rounds the corners of the screenshot (and the chrome bar, when the Browser Window style is active) so the whole composition reads as one continuous rounded shape rather than a frame glued onto a sharp-edged image.
• Drop shadow — enable the checkbox to reveal blur, vertical offset, and opacity sliders for a soft shadow cast behind the framed screenshot onto the background.

Since screenshots come in wildly different native resolutions, this tool doesn't use fixed size presets. Instead, the output canvas is always sized to your screenshot's own native pixel dimensions plus the padding and chrome bar you've configured — the exact final width and height are shown as read-only text right above the download button, so you always know what you're getting before you download.

Common use cases include portfolio project screenshots, landing page hero images, app store and product listing images, README screenshots for a GitHub project, and social media previews of a web app. If your screenshot has extra window chrome, browser tabs, or unrelated content around the edges that you'd like to trim first, run it through the Image Cropper before uploading it here.

Browser Window vs. None: Which Should You Use?

Use Browser Window when the screenshot is of a website or web app and you want viewers to immediately understand "this is a page in a browser" at a glance — it's a great fit for a web app portfolio piece, a SaaS landing page hero shot, or a marketing image for a web product. Use None for screenshots of native desktop apps, mobile app UI, or anything that isn't a browser page, since adding a fake browser chrome bar to a phone screenshot or a desktop application window would be visually misleading. The padding, corner radius, background, and shadow controls all still work great with "None" selected — you just get a clean, elevated version of the screenshot without the browser framing.

Frequently Asked Questions

Is my screenshot uploaded anywhere?

No. The entire mockup is composed locally in your browser using the HTML Canvas API. Your image never leaves your device or gets sent to any server.

Can I use this for a mobile app screenshot?

Yes — select the "None" frame style since a fake browser chrome bar wouldn't make sense on a mobile app or native app screenshot. The padding, background, corner radius, and drop shadow controls all still apply and work well for mobile screenshots. Note that this tool doesn't include a dedicated phone-bezel mockup (an outline of an actual phone body around the screen) — it focuses on background, padding, and shadow presentation instead.

What image formats are supported for upload and download?

You can upload PNG, JPG, or WebP screenshots. For download, choose between PNG (best for crisp UI screenshots with text, and supports full quality) or JPG (a smaller file size, useful when file size matters more than pixel-perfect sharpness).

Why is my output image larger than my original screenshot?

The padding you add around the screenshot, plus the browser chrome bar height if you've selected that frame style, are added on top of your screenshot's native dimensions — that's what increases the final canvas size. This is by design: the output always matches your screenshot's own resolution plus whatever framing you've configured, rather than scaling your image down to fit a fixed template size.

Can I make the browser address bar show real text?

Not in this version. The address bar in the Browser Window frame is a decorative placeholder pill shape, not editable or real text — it's there purely to help the mockup read visually as a browser window, not to display an actual URL. If you need a different kind of marketing image, such as a video thumbnail rather than a screenshot mockup, take a look at the YouTube Thumbnail Maker.
