About TabTasker
About TabTasker, a privacy-first utility platform that runs every tool inside your browser. No uploads, no file content tracking, no account.
TabTasker is a free, privacy-first collection of browser tools built by Vehicularis. Every PDF, image, audio and developer tool on the site runs entirely in your web browser using WebAssembly, WebGPU and the modern File and Web Audio APIs. Your files never travel to a server, so the tools work on confidential documents, sensitive recordings and proprietary code without exposing them to the cloud.
We started TabTasker because the default for everyday tasks like merging a PDF, removing a background or transcribing an interview had quietly become uploading those files to a stranger. Most online tool sites attach trackers, force sign-ups, watermark outputs and store uploads for analytics or training data. TabTasker takes the opposite stance: nothing leaves your device, there is no account, and there are no usage caps.
The platform now covers more than fifty tools spanning PDF editing, image conversion and AI enhancement, audio editing and on-device transcription, and developer utilities like JSON formatting, regex testing and password generation. We also ship browser-to-browser apps for file sharing and video calls over WebRTC, plus workflow templates that chain tools into one-click pipelines for common batch jobs.
TabTasker is made by Vehicularis. Read more about how we build privacy-first software on our blog, or get in touch through the contact page if you have feedback, found a bug or want to suggest a tool.
