Frequently Asked Questions

HEIC (High Efficiency Image Container) is the default photo format on iPhones and iPads since iOS 11. It produces smaller file sizes than JPG while maintaining the same image quality, but many websites and applications don't support it — which is why conversion to PNG is often needed.

With ModernPDF, your files never leave your browser. The HEIC to PNG conversion happens entirely on your device using JavaScript. No files are uploaded to any server.

No. PNG is a lossless format, so the conversion preserves full image quality from the original HEIC file. The PNG output may be larger in file size since it doesn't use HEIC's advanced compression.
