A file arrives in a format your machine does not know, and installing the program that made it is either impossible or not worth it for one document. Doconut.app is a free online viewer for that situation — from PDFs to CAD drawings, opened in the browser you already have.

Wide Format Support
Seventeen viewers cover 73 file extensions between them — PDF, DOC, XLS, PPT, PSD, DWG, SVG and the rest — with nothing to install.
The size limit belongs to the format rather than to the site, which is worth knowing before you upload: 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.
Privacy Assurance
With increasing concerns about data security, Doconut.app goes the extra mile to ensure user privacy. The platform guarantees that no documents are stored; files are immediately deleted upon viewing. This approach provides users with peace of mind, knowing that their sensitive information will not be retained unnecessarily.
User-Friendly Interface
For a document viewer to be effective, it must be intuitive and easy to navigate. Doconut.app offers a user-friendly interface that allows users to effortlessly zoom, scroll, and manage their documents directly in their browser. The layout is designed to enhance productivity, making it simple for anyone to use, regardless of their technical skills.
Cross-Device Compatibility
The viewer adjusts to the screen it is on, so a document is readable on a phone as well as a desktop. Since it is a web page rather than an app, it also works on machines where you are not allowed to install anything — which is often exactly where the problem started.
No Installation Required
Doconut.app operates directly in the browser, meaning there's no need for software downloads or installations. This feature not only saves users time but also ensures that they can access their documents instantly, promoting efficiency and productivity.
Fast and Effective Performance
Speed is crucial when it comes to document viewing. Doconut.app is designed for fast processing and quick document loading, allowing users to view their files almost instantly. This performance feature is especially beneficial for professionals who are working under tight deadlines and require immediate access to their documents.
Regular Updates and Security Features
To keep pace with ever-changing technological needs, Doconut.app releases regular updates that introduce new features and improvements. Additionally, the platform employs SSL encryption to protect data during transmission, ensuring that user information remains secure throughout the viewing process.
Conclusion
Doconut.app is a viewer, and being clear about that is the most useful thing this article can do: it opens files and it deletes them afterwards. It does not convert, edit or batch them, and there is no account, no tier and nothing to buy.
