Why people switch to a local converter
Online converters upload your private files to a stranger's server, stamp watermarks, throttle your size, and make you wait. This one doesn't.
Truly private
Your photos, contracts and videos never touch the internet. Conversion runs entirely on your Mac — even in airplane mode.
Instantly fast
No upload, no download, no queue. Files are processed at the speed of your SSD, accelerated for Apple Silicon.
No limits, ever
Convert 4K videos, RAW photos and huge PDFs as many times as you want. No size caps, no daily quota, no watermark.
One app for all of it
Stop hunting for a different website per format. Video, audio, images, documents, ebooks and archives — all in one place.
On-device superpowers
Heavy features that usually cost a subscription — running locally on your Mac, free of the cloud.
Background remover
Cut out the background of any photo with an on-device AI model (U²-Net). No subscription, no upload.
Speech to text

Text to speech

Questions, answered
Is it really 100% offline?
Yes. Every conversion runs on your Mac with bundled engines (FFmpeg, Sharp, and on-device AI models). You can disconnect from the internet and everything still works. Your files are never uploaded.
Will my files have a watermark?
Never. There are no watermarks, no quality throttling and no hidden limits on the output.
Does it run on Apple Silicon?
Yes — it's built natively for Apple Silicon (M1, M2, M3, M4). macOS 11 Big Sur or newer is recommended.
Can I batch-convert a whole folder?
Absolutely. Drop in as many files as you like and convert them in one pass. You can even set up watch folders for automatic conversion.
How is this different from an online converter?
Online converters upload your private files to a remote server, add watermarks, cap file sizes and need a connection. This is a native Mac app — faster, private, unlimited, and it works on a plane.
Convert everything on your Mac. Keep it all private.
One app for every format. No cloud, no limits, no nonsense.
