What it is
TaskNinja is a free website of tools for everyday work that run inside your browser. It helps you open files you don't have software for, such as CAD drawings (STEP, DWG, DGN, STAAD), engineering files (GraphPad Prism, JMP, Mathcad), and design files (Sketch, OneNote), without purchasing licenses. The site also offers PDF tools to compress, merge, split and unlock PDFs, photo resizing to specific file sizes, and calculators for loans, deposits and taxes. Every tool processes files on your device using WebAssembly and Web Workers, so files and text never leave your computer. There is no sign-up, no watermark and no paid plan.
What it is built with
- DWG and DXF viewer for AutoCAD drawings with layer toggling and distance measurement
- DGN file viewer for MicroStation V7 and V8 with level toggling and export to PNG, PDF or DXF

Questions from the bench
- How can I open a DWG file without AutoCAD?
- Open the TaskNinja DWG viewer and choose your file. It reads DWG and DXF in your browser with LibreDWG, allowing you to pan, zoom, switch layers and save a PNG or PDF without installing AutoCAD.
- Are my files uploaded to TaskNinja's server?
- No. All viewer, PDF, photo and calculator tools process files in your browser using WebAssembly and Web Workers, so files stay on your device and never leave it. Google Analytics and AdSense set cookies but never receive your files or text.
- Is TaskNinja really free?
- Yes. There is no sign-up, no watermark and no paid plan. Browser tools have no usage limits, and ads help keep the site running.
- How do I compress a PDF to under 1 MB or 200 KB?
- Open Compress PDF, add the file and choose a target such as 100 KB, 200 KB, 500 KB or 1 MB, or pick a quality preset. The file is compressed in your browser and never uploaded.
- Does TaskNinja work on a phone?
- Yes. Every tool works in a mobile browser on Android and iPhone. Very large CAD drawings open faster on a computer with more memory.
