Pourquoi choisir Ai2Done ?
Converting Visio .vsd files to PNG is the most common first step when you need to embed diagrams into wikis, status reports, change requests, or vendor documentation that the reader will open without Microsoft Visio installed. PNG wins over JPEG for diagrams because connector lines, callouts, swimlane labels, and small annotations stay razor-sharp—JPEG's lossy DCT smears one-pixel strokes into a fuzzy halo that auditors notice and reviewers complain about. The Ai2Done pipeline first renders the .vsd to PDF inside a sandboxed conversion service (LibreOffice headless + visio import filter), then rasterizes each page through Ghostscript at a resolution you choose (default 144 DPI for retina-quality wiki embedding). The legacy .vsd binary format is fragile—pre-2013 saves with custom stencils sometimes drop external master shapes, so we surface a clear "missing master" warning when the document references shapes we cannot resolve, instead of silently producing a half-rendered diagram. This canonical page covers the standard upload-render-download flow for any .vsd file; if you have specific scenarios (process flowcharts, network topologies, BPMN), the related SEO variants drill into render presets that prevent label clipping for those shapes.
Comment utiliser
- Upload your .vsd file (≤50 MB recommended; larger files split poorly across our render workers). Confirm the page count Ai2Done detects matches what you see in Visio—if a custom template is missing, the count may be off and you should re-save the .vsd in a newer Visio version first.
- Pick render DPI: 96 for general wiki / Confluence embedding, 144 for retina screens, 300 for print-bound diagrams. Choose "transparent background" if you'll place the PNG on a colored slide. The preview shows page 1 within ~5 seconds so you can verify text legibility before committing the full export.
- Download the PNG (single page) or ZIP (multi-page diagram). Open each PNG at 100% in your browser to confirm connector arrows, labels, and dashed lines look correct. If a specific page rendered with missing shapes, re-export that page only after fixing the source .vsd's external master references.
