Tools that never see your files
Watermark an ID copy, black out a bank statement, strip the GPS tag from a photo, turn phone snaps into a tidy PDF. Every tool runs inside your browser — your document is never uploaded, never stored and never logged.

Why browser-only matters
Most free document tools work by uploading your file to a company's server, processing it there and sending it back. For a holiday photo that hardly matters. For a passport scan, a payslip or a bank statement it is a real decision: you are handing a complete, readable copy of a sensitive document to a business you know nothing about, along with your IP address and the time you did it.
CrispUtils is built the other way round. The processing code runs inside your browser tab, using the same technology that lets a web page draw a chart or play a game. Your file is read from your own disk into your own memory and the result is written straight back to your downloads folder. Nothing crosses the network, because there is no server to cross it to.
You can check this yourself. Open your browser's developer tools, switch to the Network tab and use any tool on this site. You will see the page load, along with the advertising script that pays for it — and then nothing more. The file you opened never appears in that list, because it is never sent. Load the page once and you can even turn off your internet connection and keep working.
