Somebody sends you a file and your computer refuses it. It happens with a PSD if you have no Photoshop, a DWG if you have no AutoCAD, and a DOCX on a machine without Office — three different problems with the same shape.
Doconut.app is a free online viewer for exactly that moment. It opens 73 file extensions across seventeen viewers, including DOCX, PDF, PSD and DWG, in the browser you already have. This post covers what it opens, how large a file can be, and what happens to it afterwards.

🌍 Benefits of Using Doconut.app
🌐 Accessibility
Access your documents from anywhere, anytime. Whether you're on your computer, tablet, or smartphone, Doconut.app provides consistent performance and accessibility.
🔒 Security
Your upload travels over HTTPS, and your file is deleted once you have viewed it. Nothing is stored, and there is no account for a document to be attached to.
That last point is the substance of it: because no copy is kept, there is no archive of your documents that could be breached later. It is a real protection and also a limited one — the file is on our server while it is being rendered, and we hold no ISO 27001 or SOC 2 certification. For a regulated document, the right answer is a system your own organisation controls.
💸 Cost-Effective
Doconut.app is free to use, making it a cost-effective solution for individuals and businesses alike. Save money on expensive software subscriptions and enjoy a powerful document viewer at no cost.
🚀 Additional Features
🔀 Cross-Platform Compatibility
Doconut.app works across all major browsers and operating systems, ensuring you can access your files regardless of the device you're using.
🖼️ High-Quality Rendering
View your documents in high resolution, with accurate formatting and clear visuals. Doconut.app ensures that all elements of your documents are displayed correctly, from complex spreadsheets to detailed graphic files.
🤔 Why Choose Doconut.app Over Other Tools?
🔄 Range
Most online viewers do one family of formats. This one does seventeen — PDF, Word, Excel, PowerPoint, CAD, PSD, Visio, Project, email, TIFF, EPUB, RTF, XML, HTML, text and two image viewers — which is what makes it useful as the page you return to rather than the page you find once.
👍 Ease of Use
There is no learning curve, because there is nothing to learn. Upload the document and read it.
💯 Reliability
With Doconut.app, you can trust that your documents will be displayed accurately and promptly. Our platform is designed to deliver reliable performance every time.
📋 FAQs
What file formats does Doconut.app support? Doconut.app supports a wide variety of file formats including DOC/DOCX, XLS/XLSX, PPT/PPTX, DWG/DXF, PDF, TIFF, RTF, PSD, XML, HTML, TXT, and many others.
Is Doconut.app free to use? Yes, Doconut.app is completely free to use for all supported file formats.
Can I access Doconut.app from any device? Absolutely! Doconut.app is accessible from any device with an internet connection, including computers, tablets, and smartphones.
How secure is Doconut.app? Your file travels over HTTPS and is deleted when you finish viewing it. There is no account and no stored copy. What we do not have is a certification: no ISO 27001, no SOC 2, no HIPAA. If the document is regulated, use a system your organisation controls.
Do I need to install any software to use Doconut.app? No installation is required. Simply visit Doconut.app in your web browser and start viewing your documents instantly.
Does Doconut.app support large files? Up to a point, and the point depends on the format. Each viewer sets its own limit: 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. Over the limit the upload is refused rather than failing slowly, and there is no paid tier that raises it.
Does it convert files? No. It is a viewer. You can read a document and print it — including printing to PDF through your browser — but there is no format menu, and no conversion.
🔚 Conclusion
If a file will not open on your machine, this is a reasonable next thing to try: it is free, there is nothing to install, no sign-up, and your copy is deleted when you are finished.
