Frequently Asked Questions
How does it process my images internally?
ImageTool uses modern web APIs (like HTML5 Canvas and WebAssembly) allowing your browser to read, render, compress, and re-encode images purely using your device's local CPU power.
Can I use the app offline?
Yes! Once you have loaded the webpage on your device, the processing engine runs purely in the client. You can safely disconnect from Wi-Fi and still crop or compress your images perfectly.
Are my photos uploaded or saved on a server?
Absolutely not. Zero bits of your images ever leave your device. The entire process is strictly confidential by design.
What file formats do you support?
You can load almost any standard image (JPEG, PNG, WEBP, GIF, HEIC on supported devices). You can then export and seamlessly convert it to highly-optimized JPEG, PNG, or WEBP files.
Does compression ruin my image quality?
Not necessarily. We use highly calibrated compression heuristics. By letting you set a specific output size (KB), the algorithm attempts to preserve the absolute maximum visual fidelity while hitting your storage constraints.
