Preview almost any file, no install needed
Poka opens 1,390+ file formats right in your browser — drop a file or paste a link and see it instantly.
How to preview a file
Open Poka
Go to the Poka homepage. There's nothing to download or install — it runs in your browser.
Drop your file
Drag any file onto the page, or click Open file to browse your computer. All major formats work: images, PDFs, CAD drawings, 3D models, documents, spreadsheets, audio, video and more.
See it instantly
Your file opens in a viewer tuned to its format — interactive 3D, zoomable CAD, or plain preview. No waiting, no conversion.
Preview a file from the web
You can also preview a file hosted online:
- Copy a public link to a file (PDF, image, model, etc.)
- Paste it into the URL box on the homepage and press Enter
- Poka fetches it and shows the preview
Note: URL previews work best with public files. If a site blocks cross-origin fetching, just download the file and drop it here instead.
