Always.
CONVERTERPRO is a set of professional file and calculation 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, SheetJS for spreadsheets, and ffmpeg.wasm for video and audio. Charts are rendered with recharts.
Because nothing leaves your machine, there are no rate limits, no queues, and no privacy trade-offs. Close the tab and it's gone.
