Wrong format? Fixed where the file is.
A HEIC that will not open, a MOV that has to be an MP4, a Word file that should be a PDF. In Nemi you convert the file where it already is, across more than 100 formats, and the result lands next to the original. No upload to a website you have never heard of.
What it replaces.
- CloudConvert
- Handbrake
- a dozen tabs
It is built into Nemi and works with what is already in your account, so it is never one more thing to sign up for.
What it does.
Convert images, video, audio, documents, spreadsheets and subtitles without leaving your files.
Convert
One file in, three formats out, next to the original.
Our own Rust engine
Conversion runs on an engine we wrote, on our own hardware in the Netherlands, not on a third party service with your files passing through it. A batch of several hundred images is one action.
It lands in the folder
No download, no re-upload, no file called final_v2 (1).mov in a downloads folder.
