Turn any URL or text into a scannable QR code. Customise size and colours, then download as PNG — no watermarks, no account.
Instantly see your LAN IP, public IP, ISP, location, browser, OS, and connection type — detected in-browser via WebRTC and public APIs.

Reveal the EXIF, GPS, camera, and IPTC/XMP data hidden inside your photos — then strip it out and download a clean copy. Nothing ever leaves your browser.
Add text, cover up content with whiteout, draw shapes, or sign with a freehand pen — works on regular PDFs and scanned/non-text ones alike. Nothing is uploaded.
No tools match that search.
No heavy frameworks or unnecessary dependencies. Fast by default, not as an afterthought.
Processing happens client-side wherever possible. Your data stays on your machine — it doesn't need to go anywhere else.
Open a URL and the tool works. No downloads, no extensions, no setup steps. The browser is the platform.
Release notes, how-to guides, and articles covering the tools we publish and the technology behind them.
