You just took a screenshot of your app, now you need a nice image to post on Facebook, add to a slide, or use as a cover photo for an article. A flat screenshot looks boring, and opening Photoshop or Figma just to create a phone frame feels tedious.

Mockup Studio solves exactly that problem. Drag your image in, choose iPhone or Android, drag your mouse to rotate the device until you're satisfied with the angle, and click to download a PNG. Done. No installation, no account registration, no watermark.

The most important point: your images are never uploaded to a server. There’s no upload step because there is no server to upload to. The browser reads the file, builds the image on its own, and exports the picture. Closing the tab is all you need to do, and there’s no trace left.

MAIN FEATURES

1. Input Image — Fill or Fit

Not every image fits the aspect ratio of a phone screen. Images taken from a desktop are wide, or slightly mis-cropped images can be used:

- Fill: crops tightly without leaving any space

- Fit: shows the entire image with a neat padding border

No stretching or distortion, and no manual adjustments needed.

2. Rotate the Device as You Wish

Most mockup tools only provide a front-facing angle, which gets boring after a while. Here, you can directly pull on the device — yaw (horizontal), pitch (tilt forward and backward), roll (tilt left and right) across all three axes.

For precision, there are rotation rings and sliders for each axis. For speed, there are 5 preset angles for a simple click: Front, Left 30°, Left 45°, Right 30°, Right 45°.

3. Export the Image Exactly as You Need

No more exporting a square image with a tiny phone set against a sea of white space. The output image hugs the device frame closely, and the padding around the device can be adjusted in pixels.

- Turn off shadows when unnecessary

- Export PNG with a transparent background, ready to place anywhere

- File size automatically calculated based on the device frame

4. Small Features that Come in Handy

- Two types of devices: iPhone and Android, each with 4 frame colors

- Background: 6 preset colors, or choose any color you want to match your slide

- Interface available in 3 languages: Vietnamese, English, 日本語 — the entire interface is translated, not just the menu

SOME REAL-WORLD USE CASES

Creating a post cover: you just released a new feature, took a screenshot, tilted it 30° for depth, used a brand color background, and posted it on Facebook or LinkedIn. Takes about two minutes.

Funding slides or reports: export a PNG with a transparent background, drag it straight into Google Slides or Keynote. Works with any slide background color, no manual background removal needed.

Images on a landing page: need three mockups at the same angle for uniformity? Use the Left 30° preset, change the image three times, export three images. Angles exactly the same, no manual adjustments required.

Sending demos to clients: clients haven’t signed a contract, UI hasn’t been published, and you don’t want the images sitting on someone else’s server. This runs on your machine, so you can be confident.

Images for the App Store / Play Store: quickly create drafts for internal review before making the official version.

Internal training documents: take screenshots of the internal app, and add the device frame for clarity, without worrying about company data leaking out.

ABOUT PRIVACY

We want to clarify this section, as many online mockup tools require you to upload images to their servers.

- No uploads, ever: the file remains on your machine from the moment you open it to when you export

- Processing happens right in the browser: 3D rendering and PNG exporting all run on your machine

- Nothing saved: no accounts, no image history, no leftover copies

- Safe for sensitive matters: internal dashboards, unreleased UIs, client screens — all of it never leaves your laptop
