How to create glowing device outline mockups
This neon device mockup generator helps teams ship futuristic 3D product visuals quickly: dual-layer halos, adjustable strength, angle presets, screen fit modes, and separate preview versus export backgrounds. It is ideal for dark UI launches, gaming apps, AI tools, and high-contrast creative.
- 1
Upload your app screenshot
Drop a PNG or JPG from your app, dashboard, or game interface—or load the neon demo to preview the scene first. Processing stays local with no server upload.
- 2
Tune body and neon outline
Pick chassis presets and a glow color that matches your brand. Adjust glow strength to balance a soft outer halo against a brighter inner rim.
- 3
Frame with angles and screen fit
Choose studio, hero, or dramatic presets—or orbit freely and reset the camera. Use cover or contain so tall phone captures map cleanly to the display.
- 4
Match preview and export backgrounds
Work on midnight fog, navy, light slate, white, or a checkerboard stand-in for transparency. Export with the same look or a different one, including alpha PNG for compositing.
- 5
Export high-resolution PNG
Download a sharp PNG with long edge up to 3840 px for App Store visuals, launch pages, social campaigns, and decks.
Why glowing outline mockups stand out
Neon edge treatments increase visual separation between device and background, creating stronger depth cues than flat screenshots. This makes your product creative more scroll-stopping in social feeds and app listing previews.

Creative direction tips for neon mockups
Keep one dominant glow color with one accent to avoid visual noise. Match CTA and typography accents to your glow hue so the composition feels intentionally designed.
Export multiple glow colors from the same screenshot and A/B test in paid social placements for the best click-through performance.
Frequently asked questions
What is a glowing device outline mockup?
It is a 3D phone presentation with additive neon halos around the hardware—stronger separation from the background than a flat screenshot.
Is this glowing mockup generator free?
Yes. You can generate and export glowing device mockups for free.
Do you store uploaded screenshots?
No. Screenshot files remain local to your browser and are not uploaded.
Which image formats can I use?
PNG, JPG, JPEG, WebP, GIF, BMP, and TIFF are supported. Convert HEIC before upload.
Can I export with a transparent background?
Yes. Set export background to Transparent for an alpha-channel PNG so you can place the device on any backdrop.
What does glow strength control?
It scales the dual halo layers: a wide soft bloom plus a tighter bright rim, both driven by your neon color.
Can exported mockups be used commercially?
Yes, for your own app and client campaigns, as long as you own rights to the source UI assets.
