Dinky vs Permute
Permute converts video, audio, and images with polish. Dinky chases smaller bytes and real PDF workflows—with audio cross-converts—in a free MIT app.
Choose Permute for broad format conversion
When you routinely convert between many container and codec combinations and want a dedicated converter app for that breadth.
Choose Dinky for shrink-first images, video, audio, and PDFs
When the priority is smaller files—and audio conversions alongside visuals—plus open source, watch folders, and PDF flatten/preserve—not every possible conversion matrix.
| Dinky | Permute | |
|---|---|---|
| Focus | Compression (images, MP4 with optional FPS cap, audio, PDF) | General media conversion (video, audio, images) |
| Audio | AAC (M4A), ALAC, WAV, AIFF, FLAC, MP3 — presets in the same drop zone | Yes — audio conversions (see Permute) |
| Flatten, preserve, target size, optional OCR | Not Dinky’s comparison axis | |
| License / price | Free (MIT) | Paid (see developer) |
| Source code | Open on GitHub | Proprietary |
| Watch folders | Yes | Varies by version; check Permute |
| Processing | Local on your Mac | Local on your Mac |
Shrink-first workflow
Less catalog, more smaller files
When you are optimizing size instead of exploring every conversion format, Dinky keeps PDF flatten or preserve paths beside open-source still, FPS-capped video, and audio presets.
