macOS
Mediasmith
Convert video, photos and audio by the folder — without opening a single file.
Drag a folder in, pick what each kind of file should become, and press Process. Conversions run in parallel with a progress bar and a time estimate per file, and a file that already exists gets a numbered name rather than being overwritten.
Three queues, one window
Drop in a mixed folder and video, images and audio each land in their own queue with their own output format. No switching apps, no converting one kind of file at a time.
Video, properly
H.264, HEVC, ProRes 422 and 4444, HEVC with transparency, animated GIF, and ready-made targets for Apple TV, iPhone and iPad. Hardware encoding is used by default on Apple silicon.
Audio, including MP3
MP3, AAC, Apple Lossless, FLAC, Opus, WAV, AIFF, and 30-second iPhone ringtones. Extract the audio track straight out of a video, or downmix to mono to halve the size of a voice recording.
Images with a real pipeline
Resize, crop, rotate, watermark, border and adjust — in the order you choose, with a live preview of the result. HEIC, JPEG, PNG and TIFF out; WebP, BMP and GIF in.
Nothing is offered that cannot be produced
Every format in the list is checked against what your Mac can genuinely write before it appears. You will not pick an output and discover afterwards that it fails on every file.
Private by construction
The app ships without the network entitlement, so it cannot send anything anywhere even if it wanted to. No account, no analytics, no telemetry.
Pay once
Buy it once on the Mac App Store and it is yours. No subscription, no in-app purchases, no account, and nothing that expires. Every feature is included from the first launch.
Requirements
Available only on the Mac App Store. macOS 14.0 (Sonoma) or later, on Apple silicon or Intel. Available formats depend on what your Mac supports — the app shows you the ones it can actually write. See the terms for detail.
Open source acknowledgement
MP3 encoding uses LAME, licensed under the GNU Lesser General Public License 2.1. It is used unmodified and linked dynamically, so it can be replaced with your own build. The full licence text is included in the app, under Settings → About.
