Free, private file tools in your browser

More soon Stay tuned

More coming soon

We're adding new tools every week.

How it works

WebAssembly Initialization

Selecting a tool loads and instantiates its WebAssembly module within the browser runtime.

File Loading

Files are accessed through the File API and read into memory buffers. Your maximum file size is determined purely by your system's available RAM.

Background Processing

Processing runs on background Web Workers. This prevents the main UI thread from blocking during intensive compression or encoding tasks.

Output Delivery

Processed data is written to a Blob object and downloaded locally without network transmission.

Client Side Execution

All processing occurs in the browser using standard Web APIs. We don't have external servers.

Bypass Cloud Limits

Performance and maximum file size depend on the power of your device, not constrained by upload limits.

Native Libraries

We compile industry-standard tools like ImageMagick and FFmpeg into WebAssembly for native execution speeds.

Memory Lifecycle

Your data evaporates the moment you close the tab. No "delete from server" required, because it never left your device.
