Disk Space Visualizer
See exactly what's filling a folder — broken down by file type and top subfolders, with proportional bars. Runs entirely in your browser.
🔒 Runs entirely in your browser · nothing is uploaded or stored
🔒 Private by design
Only file paths and sizes are read, all in-browser. No file contents are accessed and nothing is uploaded.
🎯 Find the hog
The bars show proportion instantly. Big media or cache/build folders usually dominate — target those first.
Frequently Asked Questions
Is this like WinDirStat or TreeSize?
Same idea — a visual breakdown of where space goes — but it runs in your browser with zero install and never uploads your files.
Why can't it show my whole C: drive?
Browsers can only read a folder you explicitly pick, for security. Point it at large folders like Downloads, Videos or a project directory.
