About FilePeek
Open Any File. Anywhere. No Installation Required.
The Vision Behind FilePeek
In today's digital workflow, users frequently receive files in specialized formats—such as Adobe PDFs, Microsoft Office documents, proprietary .DAT flat files, JSON/XML code payloads, or ZIP archives—on machines that lack expensive software licenses or dedicated desktop viewer applications.
Historically, the only alternatives were downloading untrusted freeware software full of adware, or uploading private documents to mysterious online "cloud converter" websites. Both approaches compromise personal device security and expose confidential intellectual property.
FilePeek changes this equation entirely. By orchestrating cutting-edge browser standards—including WebAssembly, Web Workers, Canvas 2D, and the HTML5 File API—FilePeek empowers anyone to preview files directly inside their browser with instantaneous response times and uncompromising privacy.
100% Privacy by Design
File processing is confined exclusively to your browser's local sandbox memory. We do not have a backend storage database, and our server rejects all upload requests.
Zero Installation
No heavy desktop software suites, no browser extensions, and no system administrative privileges required. Works identically on laptops, Chromebooks, tablets, and phones.
Free for Everyone
FilePeek does not lock advanced features behind paywalls or require account signups. It is a clean, accessible public utility for knowledge workers, developers, and students.
Supported Platforms & Standards
FilePeek is thoroughly tested across modern evergreen web browsers including Google Chrome, Mozilla Firefox, Apple Safari, and Microsoft Edge. Our codebase is crafted in modern Angular with strict TypeScript safety, meeting WCAG AA accessibility standards.
