WALTR HEIC Converter
WALTR HEIC Converter is a free offline image conversion utility for macOS that transforms HEIC files (the HEIF format Apple uses on iOS and newer macOS devices) into more universally compatible JPEG or PNG formats. The app features a simple drag-and-drop interface, supports batch conversion of multiple files, preserves EXIF metadata including GPS coordinates and capture dates, and keeps all processing local on your computer without requiring internet access. It is designed for users who need to share or use HEIC photos across systems or applications that do not yet support Apple's newer image standard.
AI Recommendation
1 suggestionWALTR HEIC Converter has not received meaningful updates since its initial release in 2018 — the latest version on record is 1.1.4, and there is no evidence of a native Apple Silicon build being available or planned. The app continues to run under Rosetta 2 on M-series Macs, but Apple is removing Rosetta 2 in macOS 28 (late 2027), and this app will stop launching entirely on that release. Since the developer does not appear to be actively maintaining the project, we recommend considering a native alternative. If you only occasionally need to convert HEIC files, macOS itself now includes native support for HEIC — you can open HEIC files in the built-in Preview app and export them as JPEG or PNG by selecting File → Export and choosing your desired format. For batch processing or automation, look at imazing or a command-line tool like ImageMagick (available via Homebrew with native Apple Silicon support), which can convert HEIC files in bulk. Both of these alternatives run natively on M-series Macs and will continue to work after macOS 28 ships.
