The .png is written in the browser and saved straight to your downloads folder. No queue, no email, no watermark.
What survives the conversion
A file conversion is a translation, and formats do not carry the same things. Here is exactly what moves from SCAD into PNG, and what does not.
| Geometry | Dropped | The output is an image of the view, not geometry. Nothing in it can be measured or edited afterwards. |
|---|---|---|
| Colors and materials | Kept | PNG carries full color, which is at least what SCAD stores, so the colors come across. |
| Layers and structure | Dropped | The export is flat: one image, one set of pixels. Layers you switched off in the Layers panel are simply not drawn, so the output matches what you see. |
What the PNG writer emits: The current view, captured at whatever resolution you set in the export dialog. For a picture the dialog opens at the source image’s own pixel size, so a 1x export is a faithful re-save; for a model or a drawing it opens at twice the on-screen size, up to 8192 pixels wide.
The source: OpenSCAD (.scad) (.scad)
The OpenSCAD program run as OpenSCAD runs it: modules, functions, loops and every built-in solid, transform, boolean, extrusion, offset, hull and minkowski, with OpenSCAD’s exact facet counts from $fn, $fa and $fs, color() colours, and text in OpenSCAD’s own default font. include<> and use<> files are read from the same ZIP.
The target: PNG Image (.png)
A lossless image of the view, at the resolution you choose, with an optional transparent background.
Opens in: Anything.
Your file never leaves your computer
Both the SCAD parser and the PNG writer are JavaScript and WebAssembly running in your own browser tab. There is no upload step, no server-side conversion queue, and no copy of your file anywhere but your machine. That matters for drawings under NDA, for client work, and for anything you would not email to a stranger.

Frequently asked questions
▶Is this SCAD to PNG converter free?
Yes. No signup, no watermark, no per-file limit and no paid tier. Innerscene.
▶Is my SCAD file uploaded anywhere?
No. The file is read with the browser file API and converted in the same tab. Nothing is sent to a server unless you explicitly click Share, which is a separate, opt-in feature.
▶Will my colors and materials survive the PNG export?
PNG carries full color, which is at least what SCAD stores, so the colors come across.
▶Do layers and named parts carry into the PNG file?
The export is flat: one image, one set of pixels. Layers you switched off in the Layers panel are simply not drawn, so the output matches what you see.
▶How large an SCAD file can I convert?
Up to 200 MB, and the ceiling adapts to how much memory your device reports. The conversion runs on your own hardware, so a desktop with plenty of RAM will handle more than a phone.
▶Can I convert PNG back to SCAD?
Not here. We read SCAD and write PNG, but not the reverse. the universal 3D viewer
▶Which browsers does it work in?
Chrome, Edge, Firefox and Safari, on Windows, macOS, Linux, iOS and Android. No plugin and no extension.
