04 · Images in, new formats and smaller files out
Convert
Convert images between formats, resize them, and shrink their file size.
When to reach for it
Use for any image file-format change (HEIC or TIFF to PNG, PNG to WebP, anything to PDF), to make images smaller for the web, or to cap their dimensions. Reads PNG, JPEG, WebP, GIF, BMP, ICO, AVIF and SVG everywhere, plus HEIC, TIFF and PSD on macOS. Not for logo deliverable packages; use Lockup for those.
What lands on disk
One converted file per source per format. With several formats, each gets its own subfolder (PNG/, WebP/, …).

Without the window
The same tool from a terminal or an agent. Identical output either way, because the app and the command line run the same code.
