Privacy & Security
All file processing for HEIC to JPG on iPhone happens exclusively inside your browser tab. utool uses WebAssembly (WASM) compiled from open-source libraries to perform operations locally on your device. At no point during the process is any data transmitted over the network. You can verify this yourself by opening your browser's Network Inspector (F12 → Network) and observing that no file upload requests are made.
Common Mistakes to Avoid
- 1Not checking the output file before closing the browser tab — always preview or save the result first.
- 2Using an outdated browser — utool requires modern WebAssembly support. Update to the latest version of Chrome, Firefox, or Safari.
- 3Trying to convert HEIC to JPG a password-protected file directly — remove protection first using the utool Unlock PDF tool.
