Aura by ZepheniaLabs

Aura is a media conversion app for iPhone, iPad, and Mac that does everything on your device. No uploads, no accounts, no tracking — your files never leave your hands. Every conversion is a real conversion. Aura fully decodes each file and re-encodes it in the format and settings you choose. Nothing is renamed, skipped, or faked. Aura is built around four Spaces: SOUND — Convert audio between MP3, AAC, ALAC, FLAC, WAV, AIFF, Ogg Vorbis, Opus, APE, and WavPack. Set bitrate, bit depth, and quality, and convert whole batches at once. TAGS — Read and edit audio metadata: title, artist, album, genre, year, track, composer, comment, and artwork. Tags embed straight into the file wherever the format allows. Tags is completely free. VISUAL — Convert images between JPEG, PNG, HEIF, TIFF, and BMP, with quality and resize controls. WebP, JPEG XL, GIF, and more are accepted as inputs. MOTION — Convert video to MP4 or QuickTime with hardware-accelerated H.264 and HEVC, plus the full Apple ProRes family on supported devices. Set resolution up to 4K, cap the frame rate, and choose how audio is handled — with live progress as it runs. Pay only for what you use. Unlock the Sound, Visual, or Motion Space on its own with a single one-time purchase, or get the Aura Pass to unlock every Space, now and in the future. Each paid Space includes free conversions to try first. There are no subscriptions. Private by design. Aura runs every conversion locally using Apple's native frameworks. No telemetry, no analytics, and no network activity beyond the App Store itself. Built for Apple. A native interface across iOS, iPadOS, and macOS, designed to feel at home on every device.
