Why this job: picked by hand
What it does
- A donut at the cursor. hold a key, drag files and drop them on a format.
- Straight from the browser. drag a picture, a link to a file or a download out of Chrome, Edge, Firefox or Safari the same way.
- Two sides to every donut. press Tab or turn the mouse wheel while it is open to flip it over to less common formats and tools.
- Crop before converting. the Crop slice opens pictures one by one.
