File Peek

I started FilePeek because I wanted a simple way to inspect files without having to open a different application for every file type. What started as a basic image metadata viewer turned into a much bigger tool for inspecting, comparing, previewing, converting, sanitizing, and editing files.The biggest challenge was making all these different file types work together in one interface. I had to deal with everything from EXIF data and PDF previews to ZIP archives, hex data, media files, and binary formats.I’m most proud of how far the project grew from the original idea. FilePeek now has hundreds of features packed into a single browser-based tool, while keeping the main idea simple: drop in a file and see what’s inside.Everything is processed locally in the browser, so you can inspect files without uploading them to a server.
