Ernzi Tools is a free collection of online tools for everyday tasks: compress and convert images, merge and split PDFs, trim videos, remove image backgrounds, generate QR codes, count words, and more. Every tool runs entirely in your browser — your files are processed on your own device and never uploaded to a server.
The site is run by the Ernzi Tools team. We build and maintain this collection because we believe useful utilities should be free, fast, and private, with no accounts, no installs, and no watermarks.
Ernzi Tools is built on the open-source Omni Tools project, released under the GNU General Public License (GPL-3.0). We are grateful to its contributors and to the wider open-source community. The site itself is hosted on Cloudflare Pages.
We take privacy seriously. Tools process your files locally in your browser, and we do not see, store, or share them. The site shows ads through Google AdSense; you can read the details in our Privacy Policy. If you have a question, a suggestion for a new tool, or found a bug, please reach out via our Contact page — we read every message.
