Frequently Asked Questions

Yes. Every tool on CanvasConvert Pro runs entirely on your local machine using WebAssembly. Because server compute costs are eliminated, all 130+ tools are 100% free with no paywalls, file size limits, or watermarks.

You can verify client-side processing at any time by opening your browser's Developer Tools (Network Tab). During conversion or compression, 0 bytes of payload data are sent over HTTP/HTTPS to external servers. All binary manipulation occurs inside in-memory WebAssembly routines.

WebAssembly (WASM) is a low-level binary code format that runs at near-native speed directly inside modern browser engines. It allows compiled image & document codecs to run locally on your GPU/CPU without network transmission overhead.
