Pro Tips

Frequently Asked Questions

Is this really private?
Yes, 100%. The tool uses HTML5 Canvas API in your browser. Open browser DevTools (F12) → Network tab and verify zero image data is transmitted.
Does it work offline?
Yes. Load the page once, then disconnect from internet. The tool continues to work because all processing is client-side JavaScript.
Why should I care about uploading?
Many "free" image tools upload your files to their servers for processing. Those files may be stored, analyzed, or used for training AI models. Our tool avoids this entirely.
