common questions
Are split.tools utilities really free?
Yes — every tool is free with no accounts, no watermarks, and no file-size tiers. Because files are processed on your own device, there are no per-file server costs to pass on.
Are my files uploaded to a server?
No. All splitting happens locally in your browser using standard web APIs. You can verify this in your browser's network inspector, or by using the tools with your internet connection turned off.
What can I split?
Images (into grids and tiles), PDFs (by picked pages, ranges, or fixed chunks), audio (into tracks at markers or silences), and video (into clips marked on a timeline).
Do the tools work offline?
Once a tool's page has loaded, the splitting itself runs without a connection — the clearest proof that nothing is uploaded.
why it's fast
The mat is your machine.
There is no server on the other end. Files are opened, cut and repacked by your own browser — which is why a 200-page contract or a full-resolution photo splits the moment you press the button, and why nothing sensitive ever needs to leave the room.
