Image conversion, processed locally in your browser — Private, Free & Powerful
widantoo is a fully client-side image format converter — your images are never uploaded to any server. Free, no watermark, no sign-up, no usage limits.
widantoo handles image format conversion, camera RAW developing, compression, and cropping entirely within your browser. Nothing is uploaded, stored, or transmitted. We differentiate ourselves through local RAW conversion — a genuine hard-to-fill need — and a comprehensive image format knowledge base, setting us apart from thin, upload-based tools.
Our Four Commitments
Privacy & Security
All processing happens locally on your device. Your images are never uploaded, stored, or transmitted.
RAW Conversion Done Right
Develop camera RAW files to JPG directly in your browser — a real need that very few tools handle well.
A Real Format Knowledge Base
In-depth format explanations and comparisons to help you truly understand how to choose the right format.
Completely Free, Zero Friction
No account, no limits, no watermark, no sign-up. Just open and use.
What We Don't Do
We don't upload your images to any server. We don't integrate third-party analytics or ads. We don't build account systems, and we don't pursue monetization. We focus on one thing: getting image processing done cleanly, quickly, and trustworthily — on your own device.
