Welcome to Doconut.app. Whether you are a professional, a student or someone who was just sent a file they cannot open, this is a free viewer that opens it in your browser. This FAQ answers the questions people actually send us: what it opens, how big a file can be, and what happens to it afterwards.
What is Doconut.app?
Doconut.app is an free online document viewer designed to support various file types. It allows users to upload and view documents without the need for registration or payment. Our platform is built with user convenience in mind, providing an intuitive interface and a secure environment for handling documents.
Is Doconut.app Free to Use? 💸
Yes, our website is completely free to use! We believe in providing easy access to document viewing without any cost. You can upload and view various documents without the need for registration or payment. We also prioritize your privacy, ensuring that no personal information is collected or shared.
Supported Document Formats 📂
At Doconut.app, we understand the need for versatility in document viewing. That's why we support a broad range of formats:
Text Documents 📝
Our free online document viewer handles popular text formats, including DOC, DOCX, and PDF. Whether you're reading a report, a thesis, or an e-book, Doconut.app makes it easy to access your text documents.
Spreadsheets 📊
For spreadsheet enthusiasts, we support XLS, XLSX, and CSV formats. This ensures that you can view and analyze data, financial records, or any other spreadsheet-based information effortlessly.
Presentations 📈
Need to review a presentation? Doconut.app supports PPT and PPTX files, allowing you to view slideshows and presentations with ease.
Images 🖼️
Image files like JPG, PNG, and TIFF are also supported. Whether it's a photograph or a scanned document, you can view images in high quality.
Specialized Formats 🧩
We also handle more specialised formats, such as VSDX (Visio diagrams), DWG (CAD drawings) and EML (email files).
Altogether the site accepts 73 file extensions across seventeen viewers. The one notable absence is DICOM: .dcm and .ima are deliberately left out of the free viewers, because medical imaging belongs to a separately licensed plugin of the .NET SDK.
Privacy and Security Policies 🔒
The short version: your file is deleted after you view it, and there is no account for it to be attached to.
Data Storage and Sharing 🚫
When you upload a document to Doconut.app, it is processed in real-time and not stored on our servers. After viewing, the file is immediately deleted. We do not access, read, or share your files with any third parties, ensuring that your data remains completely private and secure.
Security Measures 🛡️
Your upload travels over HTTPS, so it cannot be read in transit, and the file is deleted when you finish viewing it.
The strongest thing we can tell you is what is absent rather than what is present: because nothing is retained, there is no archive of your documents to be breached, and no account history to be exposed. That is a real protection, and it is also not the same as a certification. Doconut holds no ISO 27001 certificate and no SOC 2 report. If your document is regulated, the right answer is to keep it inside a system your own organisation controls.

Occasionally, users may encounter issues when viewing documents on Doconut.app. This section provides guidance on resolving common problems.

File Size Limits 📏
There is no single limit for the site. Each viewer sets its own, so the number that matters is the one for the format you are opening:
| Limit | Formats |
|---|---|
| 25 MB | PDF, PSD, TIFF, Visio, EPUB, and both image viewers |
| 20 MB | Excel, PowerPoint, Project |
| 15 MB | Word, RTF |
| 10 MB | CAD (DWG, DXF, DGN), email |
| 5 MB | Text, XML, HTML |
Over the limit, the upload is refused rather than left to fail slowly. There is no paid tier that lifts it and no way to request an exception, so if your file is larger, the practical options are to reduce it or to open it in an application that runs on your own machine.

Conclusion 🎉
That is the whole product: pick a file, read it, and it is gone when you close the tab. No account, no cost, and a size limit that depends on the format.
If what you actually need is this rendering inside your own application rather than in a browser tab, the same engine is sold as a .NET SDK on Doconut.com.
