HEIFree helps reclaim iPhone and iPad storage by converting existing JPG/PNG photos to HEIF and H.264 videos to HEVC, saving 40-60% storage in many cases while preserving visual quality. Unlike ordinary photo compressors that simply lower JPEG quality, HEIFree uses Apple's HEIF and HEVC support to re-encode media into more efficient formats. KEY FEATURES - Batch scan photos and videos in your library - Convert JPG/PNG photos to HEIF - Convert H.264 videos to HEVC - A/B preview comparison so you can check quality before converting - Adjustable quality slider for photo conversion - Optimized copies are saved separately by default - Optional original deletion only after your confirmation - Deleted originals go to Recently Deleted, where they can be recovered for 30 days - All photo and video processing happens on your device FREE TO TRY Your first 50 conversions are free. Unlock unlimited conversions with a one-time purchase - no subscription. PRIVACY FIRST HEIFree processes photos and videos locally on your device. Your photos and videos are not uploaded. No tracking. WHY HEIF? HEIF (High Efficiency Image Format) uses the same compression family as HEVC video. It can produce files 40-60% smaller than JPEG at similar visual quality. iPhones have used HEIF for new photos since 2017, but older photos, screenshots, and images saved from other apps may still be JPG and take more space than necessary.
