Dinky
Dinky vs PDF Expert
PDF Expert is the Mac App Store–familiar PDF editor—great for reading, markup, and forms—while file shrink is typically an export step with a quality slider. Dinky is compression-first, wraps flatten and preserve paths in open source, and shares one window with still images and MP4.
Choose PDF Expert if you live in PDF markup
When highlights, signatures, and page surgery matter most and smaller exports are a sidebar to editing—verify current pricing and compression options in the product.
Choose Dinky for batch PDF shrink plus media
When queues, presets, watch folders, and target-size PDF passes sit next to WebP and video exports—and you want the whole stack auditable under MIT.

Compression-first
Queues and targets, not just export
When PDFs need flatten, preserve, OCR, or an exact size ceiling—and the same inbox has images or video—Dinky keeps everything local in one MIT-licensed drop zone.
