How it works

Files stay on
your device.
Always.

ALL IN ONE CONVERTER is a set of professional file utilities that runs entirely in your web browser. When you drop a file into any tool, it is loaded into memory locally — nothing is uploaded, nothing is logged, nothing is stored.

We use the same open-source libraries trusted by production teams worldwide: Mozilla's pdfjs for PDF parsing, pdf-lib for PDF generation, docx for Word output, and SheetJS for spreadsheets. Image work uses the native Canvas API.

Because nothing leaves your machine, there are no rate limits, no queues, and no privacy trade-offs. Close the tab and it's gone.
