Many devices cannot natively open MPP or Visio diagrams, and installing heavy desktop software is not always possible or necessary.
DoconutApp solves this by offering a free, browser-based viewer that instantly renders:
- Microsoft Project files: MPP and MPX, up to 20 MB
- Visio diagram files: VSD, VSDX, VSDM, plus the stencil and template variants VSS, VSSX, VST, VSTX, VDX and VSX, up to 25 MB
Upload the file and read it in the browser — no setup, no add-ons, no installation and no account. Your file is deleted when you close the tab.
Почему стоит использовать DoconutApp для файлов проектов и диаграмм?
Both formats have the same underlying problem: the file is useless to anyone without an expensive licence for the application that wrote it, and that is usually most of the people who need to read it.
- No installation and no Microsoft Project or Visio licence
- Zoom, pan and move between sheets or pages; in a project plan you can also search for a task or a person by name
- Responsive interface on desktops, tablets and phones
- HTTPS upload, and the file deleted when the viewing session ends — there is no account and nothing kept
- Reading only: nothing you do here changes the plan or the diagram, and there is nothing to save back
This makes it ideal for professionals, students, and anyone who needs a quick way to inspect project data or diagrams across different devices.
Поддерживаемые форматы — фокус на проектах и диаграммах {#supported-formats}
| Категория | Форматы | Ограничение |
|---|---|---|
| Project | MPP, MPX | 20 МБ |
| Visio | VSD, VSDX, VSDM, VSS, VSSX, VST, VSTX, VDX, VSX | 25 МБ |
Two things not on the list: .mpt, the Project template, is not accepted, and a Project plan exported as XML is not a Project file as far as the viewer is concerned. Doconut.app covers 70+ extensions in total, so the rest of what lands in your inbox has a page too.
Производительность — оптимизировано для больших диаграмм и планов проектов {#performance}
Rendering happens on our servers rather than in your browser, which is what makes these formats practical on an ordinary laptop or a phone — your device only has to display pages that arrive ready to draw.
What you actually wait for:
- The upload, usually. On a slow connection a 20 MB plan takes as long to send as anything else that size.
- The document's complexity, not its page count. A diagram dense with shapes and connectors costs more to draw than a long, simple one.
We are not going to publish a stopwatch figure measured on a machine that is not yours. Test it with your own worst file — that number is the only one that matters.
Встраивание DoconutApp в ваше .NET‑приложение {#embedding-doconutapp}
Everything above describes Doconut.app, our free public site. It has no API and nothing to install — it is a page you visit.
If you need the same MPP and Visio rendering inside your own product, that is a separate, licensed product: the Doconut SDK, a .NET component installed in your environment, which renders on your servers and makes no calls back to us. Branding, permissions and retention belong there, because they only mean anything when you control the application around the viewer.
For now, if you just have a plan or a diagram to read: open the Просмотр проектов or the Просмотр Visio and drop it in.
