Why use this tool?
Use this free browser utility when you need a focused result without installing desktop software or creating an account. The workspace is designed for a single task, with the input, controls and output kept together.
Privacy, compatibility and limitations
This browser tool processes the input locally and does not send it to a remote validation service.
Before you download: Check the output visually or technically before replacing an original file. Browser support, device memory and source-file structure can affect results.
