What is Dinky?
A small macOS utility that compresses images, videos, and PDFs. Drop files in, get smaller ones back.
For images: supports JPG, PNG, WebP, AVIF, TIFF, and BMP. Outputs WebP, AVIF, or lossless PNG depending on your preference. For video: export to MP4 with H.264 or HEVC and quality presets. For PDFs: flatten pages (default) for reliable smaller files on most scans and image-heavy documents, or preserve text and links for a best-effort stream rewrite when size is secondary. Strips metadata (where applicable), respects max dimensions and file size targets for images, and saves next to the original by default.
