Most "free online tools" share a dirty secret: you upload your PDF, image, or text to their server. For a contract, an ID scan, or a private spreadsheet, that's a real privacy problem — your file now lives on someone else's machine.
So I built Tooljar — 50+ everyday utilities that do all their work inside your browser. No uploads, no accounts, no ads, and it keeps working offline. If a tool processes a file, that file never leaves your device.
What's in it
50 tools across PDF, image, text, developer, design and security categories. A few I lean on daily:
PDF Compressor and Merger/Splitter — re-compress and reorganize PDFs locally with pdf-lib + PDF.js.
