Does my screenshot get uploaded anywhere?
No. Plinth runs entirely in your browser: your screenshot is placed, rendered and exported on your own device and never sent to a server. That makes it safe for unreleased work and client projects.
Is it really free?
Yes. Every mockup and every export size is free, with no account and no watermark.
Do I need an account?
No. There's nothing to sign up for. Open the page, add your design and export. Nothing about you or your work is stored anywhere but your own device.
What size screenshot works best?
Use the screen's own shape: website shots around 1440 × 900 for laptops and displays, full-height app screens around 1179 × 2556 for phones, 2048 × 1536 for tablets and 410 × 502 for watches. Anything close is shown whole; otherwise choose Fit inside.
Why am I only seeing some mockups?
After you add your design, Plinth shows the mockups whose screens match your screenshot's shape, so nothing gets awkwardly cropped. Turn off "Only scenes that fit" in the editor to see them all.
Which devices are included?
MacBook Pro, iPhone, Galaxy, iPad Pro, Studio Display and Apple Watch.
What can I export?
JPG, PNG or WebP in three sizes: Web (1600 px on the long edge), Large, and Full, the sharpest each mockup allows (about 3000 px on most, 4000 px on Apple Watch). Choose the mockup's own shape or a social crop, and, if you like, export 16:9, 1:1 and 4:5 crops together in one zip.
Is my design saved anywhere?
Only in this browser. Plinth keeps your last screenshot and settings on this device, so a reload doesn't lose your work. Nothing is sent anywhere. Clear it any time from "On this device" in the editor.
Can I use the mockups commercially?
Yes. The images you export are yours to use anywhere, including client work, app stores, ads and social posts, with no credit needed. Please don't resell or redistribute the blank mockup scenes themselves.
