Dinky
Dinky vs Adobe Acrobat
Acrobat is the everything-PDF subscription. Dinky is shrink-first next to images and video, in a small open-source download.
Choose Acrobat for full PDF authoring
When you need editing, redaction, e-sign, compliance tooling, or org-wide Acrobat workflows—not only bytes shaved off an export.
Choose Dinky for straight shrink jobs on disk
When the task is mainly smaller PDFs (and often batches of images or MP4s too) without installing a large suite or paying a subscription.
| Dinky | Adobe Acrobat | |
|---|---|---|
| Scope | Compression-first + images + video | Full PDF product suite (see Adobe) |
| PDF compression | Flatten, preserve (qpdf path), target size, optional Vision OCR on scans | Optimizer and pro PDF tools (see Acrobat) |
| Still images | Yes (WebP, AVIF, HEIC, PNG, …) | Not Dinky’s primary comparison axis |
| Video | Yes (MP4 export) | Not Dinky’s primary comparison axis |
| Install footprint (approx.) | ~33 MB | Much larger (hundreds of MB class; verify current installer) |
| Price | Free (MIT) | Subscription (see Adobe) |
| Processing | Local on your Mac | Desktop app; some features may use cloud (see Adobe) |
Without the suite weight
Flatten, preserve, optional OCR
Reach for Dinky when the job is smaller PDFs and sensible scan handling—not another Acrobat install—next to stills and video in one window.
