What is a .DIA file?
A DIA file is a flowchart, network map, UML, or similar diagram made with Dia, a free open-source diagram editor from the GNOME project. Open it with Dia (Windows/macOS/Linux) or import it into draw.io / diagrams.net. To share it, export to PDF, PNG, or SVG from inside Dia.

Can I open an .AI file without Illustrator?
Yes. Illustrator files saved with "Create PDF Compatible File" (the default since CS) contain a full PDF, which we render with pdf.js. Older PostScript-based AI files are rendered with Ghostscript. Layers and editable paths aren't shown; you get an accurate picture of the artwork.
Why does my EMF or WMF look slightly different?
Windows metafiles are drawn by our own renderer, which handles shapes, lines, fills, text and bitmaps, but not every rarely used GDI feature (clipping regions, raster operations, EMF+ effects). The file details list anything that was skipped.
Is my .DIA file uploaded anywhere?
No. Everything runs as WebAssembly and JavaScript. The first EPS or PS file downloads its renderer (about 16 MB) once; after that it's cached.
Can I convert EPS to PNG or PDF?
Yes. Pick a resolution (up to 600 dpi) and press PNG, or press PDF to get a vector PDF made by Ghostscript.
Does it play Flash (.SWF) files?
Yes, with Ruffle, an open-source Flash emulator. Most animations and many games work; complex ActionScript 3 content may not.
