About Us & Contact

ChenXi Tools is a completely free collection of 26 online tools across five categories: PDF processing, image editing, video processing, peer-to-peer file transfer, and text & developer utilities.

We believe good tools should have no barriers: open the page and start using them — no account, no usage limits, and no watermarks on your output.

Every tool on this site runs locally in your browser. Thanks to modern browser capabilities such as PDF rendering, Canvas image processing, WebCodecs video encoding and WebRTC peer-to-peer transfer, your files never need to be uploaded to any server.

File transfers use encrypted browser-to-browser connections; our server only relays the handshake needed to establish them. See the Privacy Policy for full details on data handling.

ChenXi Tools is independently developed and maintained by an individual. To cover hosting and domain costs, pages may display modest third-party ads (such as Google AdSense), but we will never charge users or lock features behind a paywall.

The tools themselves stay truly free, sign-up-free and watermark-free.
