Dinky
Dinky vs fre:ac
fre:ac is a free, open-source audio converter and ripper with wide codec coverage on macOS and Windows. Dinky keeps a tighter audio preset line inside a compression-first Mac app for stills, MP4, and PDFs too.
Choose fre:ac for audio library conversions
When you need many output formats, tagging, and rip-oriented workflows—and are fine with an audio-first app surface.
Choose Dinky for shrink-first mixed media
When the day mixes WebP/AVIF/HEIC stills, optional FPS-capped MP4, flatten or preserve PDF paths, and practical audio exports—with watch folders and inspectable MIT source in ~35 MB.

Same Mac, fewer apps
Audio next to images and PDFs
fre:ac is hard to beat for batch audio jobs; Dinky fits when those exports sit beside still encodes, MP4 presets, and PDF routes you already batch in one window.
