I was clearing space on my portable drive and found it full of huge PSD stationery mockups. I barely use them, but somehow I kept them. So I built Kertas (“paper” in Indonesian), a free tool that turns any image into a realistic paper mockup right in your browser. It’s there whenever you need it, so you don’t have to keep giant files around.

What it does:

No fixed templates. The mockup respects and follows the size of your image.
Real paper in 3D. Turn, bend and curl your image, with real light and shadow.
A transparent PNG becomes a die-cut sticker, with an optional holographic finish.
Exports. Save a hi-res PNG or an MP4 video.
Private. Nothing is uploaded, so your images never leave your device.
Free, no sign-up. There’s a tip button if you’d like to support it.

Try Kertas now, I’d love feedback, especially from designers:

Did anything break on your device or browser?
Would you use it for a Behance post or your portfolio site?
What’s missing? A feature, a preset, a paper type?
