PixPack is a macOS app. It requires macOS 14.0 or later and runs on both Apple Silicon and Intel Macs.

PixPack is $9.99 on the US Mac App Store. It is a one-time purchase, not a subscription.

PixPack is distributed through the Mac App Store, so it is reviewed by Apple and updated through the App Store.

Yes. PixPack processes a batch in a single pass. You can add many files, apply one set of settings to the whole queue with Apply to All Files, and export the batch together.

Yes. PixPack can process an entire folder tree in a single batch, and you can drag a folder onto the app to start immediately.

It depends on the source image, the output format and the quality level you choose. PixPack reports the original size, compressed size, space saved and savings ratio for every file before you export.

No. PixPack exports compressed copies to the output folder you choose. Your originals are unchanged unless you deliberately export into the same folder.

PixPack does not publish a fixed maximum batch size. Practical limits depend on image sizes, available memory and disk space, and the settings you choose.

PixPack reads JPEG, PNG, HEIC, WebP, GIF, BMP, TIFF.

PixPack can export JPEG, PNG, HEIC, WebP, GIF.

Yes. WebP is one of the five output formats PixPack supports, so PNG files can be converted to WebP as part of a batch.

Yes. HEIC is both an input and an output format in PixPack, so JPEG, PNG and other readable formats can be converted to HEIC.

PNG and WebP both support transparency. Choose one of those output formats if your images rely on an alpha channel. JPEG does not support transparency.

The Format Advisor inspects each image and recommends the output format that saves the most space at the quality you have selected.

Yes. PixPack provides a quality slider for precise control, plus a Smart Recommend Quality button when you would rather let PixPack choose a level.

Yes. PixPack shows a before-and-after preview with slider and side-by-side comparison modes, plus zoom and pan, and reports the size and savings for each file.

Yes. Version 1.4.3 added rotation of 90°, 180° and 270° as part of the compression pipeline.
