Does OmniConvert genuinely work without internet once added to home screen?

Yes! Service Worker caching and WebAssembly decoding libraries are stored on your local device. You can convert files without Wi-Fi or cellular service.

Will batch converting iPhone HEIC photos degrade visual sharpness?

Not at all. OmniConvert performs pixel-level canvas rasterization, retaining 100% of native Apple camera dynamic range while stripping invasive GPS metadata.

How can I remove it later if desired?

Just like any native smartphone app: touch and hold the OmniConvert icon on your home screen, then tap 'Delete App' / 'Remove Bookmark'.
