Biz Tray is a Windows document utility belt that brings every essential file tool into one lightweight desktop app — without the upload. Where most document tools push your files to a cloud server, Biz Tray does the opposite: it converts, splits, merges, organizes, and signs your Office and PDF files right on your own PC. Nothing leaves your machine, so your contracts, statements, and sensitive paperwork stay private by default.
The app packs seven core tools into a single clean interface. You can convert Office documents to PDF, turn PDFs into other formats, convert images to PDF, switch between Office formats, organize and edit PDFs, apply finishing touches, and fill and sign forms. Because everything runs locally, there are no upload limits, no file-size caps, no quotas, and no watermarks. Batch processing lets you handle an entire folder in a single pass rather than one file at a time, and the whole app works fully offline.
Biz Tray is built to be genuinely user-friendly: there's no account to create, no email to hand over, and no ads cluttering your workflow. Rather than charging subscription fees or monetizing your attention, Biz Tray uses a transparent funding model that shares spare bandwidth to keep the tools free for everyone.
