Research groups deal in file formats that nobody outside the group has software for: a schematic in SVG, a workflow in Visio, an instrument export nobody can open on a laptop. Doconut.app opens 70+ of those extensions in a browser, free, with no account and nothing installed, and deletes the file when you close the tab.
One exclusion to state up front, because it matters in a lab: DICOM is not supported. .dcm and .ima are deliberately left off the free viewers, since a DICOM file carries patient identifiers alongside the image and a public upload endpoint is the wrong place for it.
Designed for Research Needs
At Doconut.app, we understand the challenges of visualizing diverse document formats in research settings. Whether you're analyzing data, preparing reports, or collaborating on experiments, our platform has you covered:
- SVG, up to 25 MB: vector graphics that stay sharp at any zoom — molecular structures, equipment schematics, technical diagrams. The same viewer takes EPS, TIFF, DNG and CDR, applies embedded ICC profiles, and shows a photograph's EXIF beside it.
- Visio, up to 25 MB: VSD, VSDX and the stencil and template variants, for experiment planning and workflow diagrams. You read them; you do not edit them.
- PDF up to 25 MB, Word up to 15 MB, Excel up to 20 MB for the papers, protocols and data tables around the work.

With Doconut.app, you don’t have to take our word for it—experience it yourself! Our online document viewer lets you explore all the features designed to make your research workflow smoother and more efficient.
Why Choose Doconut.app?
- Nothing to install: Useful on a managed lab machine where you do not have admin rights.
- Works on any device: Rendering happens on our servers, so an old workstation opens a heavy file as readily as a new one. There is no shared workspace and no collaboration here — each person opens their own copy.
- Nothing kept: HTTPS on the way in, deleted when the session ends. We hold no certifications, so unpublished or sensitive research should stay on your own systems.
How to start
- Go to Doconut.app.
- Drop your file on the page.
- Read it.
There is no step involving an account. Doconut.app has no sign-up, no trial and no paid tier — it is free, permanently, because it is a shop window for the SDK rather than a product with a price list.
If your own lab software needs to display these formats to its users, that is the other product: the Doconut SDK, a licensed .NET component that runs on your servers — and the one place DICOM is available, through its separately licensed plugin.
