A file arrives, and the machine in front of you refuses to open it. Doconut.app exists for that moment: upload the file, read it in the browser, and it is deleted when you close the tab. No download, no install, no account.

Key Features of Doconut.app

Wide Format Support: Doconut.app supports a broad spectrum of file types including:
- PDFs
- Word documents (DOC, DOCX)
- Excel spreadsheets (XLS, XLSX)
- PowerPoint presentations (PPT, PPTX)
- Images (PSD, TIFF, SVG, JPG, PNG, GIF, BMP, WebP)
- CAD drawings (DWG, DXF, DGN)
- Emails (EML, MSG, EMLX)
Seventeen viewers cover 73 extensions in total. The size limit belongs to the format rather than to the site: 25 MB for PDF, PSD, TIFF, Visio, EPUB and images; 20 MB for Excel, PowerPoint and Project; 15 MB for Word and RTF; 10 MB for CAD and email; 5 MB for text, XML and HTML.
User-Friendly Interface: The platform features an intuitive design that enables users to upload and view documents directly from their browser. Reliability and accessibility are at the forefront of Doconut.app’s user experience, making it ideal for professionals, students, and casual users alike.
No Installation Required: With Doconut.app, users can access documents instantly without the hassle of software installations or creating accounts. This feature not only saves time but also ensures a smooth user journey.
Cross-Device Compatibility: Whether you're using a smartphone, tablet, or desktop, Doconut.app is optimized for all devices, delivering a consistent and responsive document viewing experience.
Nothing is kept: your document is deleted after viewing. It is not stored, indexed or shared, and since there is no sign-up, there is no account for it to be attached to. That absence is the strongest privacy property the site has — no retained copy is a thing that cannot leak later.
HTTPS throughout: uploads travel encrypted, so the file cannot be read in transit. What we do not have is a certification: no ISO 27001, no SOC 2. For a regulated document, use a system your own organisation controls.
Ease of Navigation: Users can easily navigate through pages, zoom in and out, and utilize other features to enhance their viewing experience, all within a simple and effective interface.

Why Choose Doconut.app?

Doconut.app stands out in the crowded landscape of document viewers due to its unique combination of features:

It views, and only views. There is no conversion, no editing and no batch upload — one file at a time. Knowing what a tool does not do saves more time than any feature list.
Free with no tier. No account, no subscription, and nothing that expires. There is also no paid plan that raises the size limit, because there is no paid plan.

The Catalogue Does Grow

Formats get added. September 2026 brought AVIF, JP2, EMF, WMF, JPE, EMLX, MPX and MHT, along with the macro-enabled and template variants of the Office formats — which had been refused on the theory that a public upload endpoint should decline macros, until somebody noticed the viewer renders files rather than running them.
