What is PixPack?
PixPack is a native macOS image compression and optimization app
PixPack is a native macOS image compression and optimization app for compressing individual images, batches, and folders locally. It supports JPEG, PNG, HEIC, WebP and GIF output, with quality control, resizing, presets, metadata management, before-and-after preview, clipboard paste and workflow features for web, email, apps, social media and documentation.
PixPack is built for people who work with images in volume: web and app assets, email attachments, photo libraries, marketplace listings and documentation screenshots. It replaces the repetitive loop of opening one image, choosing settings and exporting with a single batch queue that is configured once and exported in one action.

Compare
How PixPack differs from other tools
Fact-based comparisons using Yes, No and Not verified — no scores, no rankings.
PixPack vs ImageOptim
The two apps approach the problem from different directions: ImageOptim optimises existing files in place with minimal configuration, while PixPack gives you explicit control over output format, quality and dimensions across a batch.
PixPack vs TinyPNG
The core difference is where the work happens. TinyPNG is a hosted service reached through a browser, with a free tier and paid plans. PixPack is a local Mac app with a one-time purchase and no upload step.
PixPack vs Squoosh
Squoosh is excellent for inspecting one image in detail. PixPack is built for volume: queues, folders, presets and a single export step for the whole batch.
PixPack vs XnConvert
XnConvert is a general-purpose batch converter with a very broad action set across three platforms. PixPack is narrower: a Mac-only tool built around image compression with a preview-first workflow.
PixPack vs macOS Preview and Built-in Tools
Preview is already on every Mac and costs nothing. PixPack exists for the cases Preview does not cover well: many images, an entire folder, format conversion, and a before-and-after comparison before exporting.
