Batch Image Compression on Mac

Overview

Batch compression in PixPack lets you queue up many images, arrange their order, apply a single set of export settings, and write all of the compressed results to a folder in one action.

What batch compression is for

Batch compression is useful whenever you have more than a handful of images: a folder of product photos, a set of website assets, a screenshot archive, or the images attached to documentation.

Instead of opening each file, choosing settings, and exporting repeatedly, you configure the batch once and let PixPack apply it across the queue.

How to batch compress images with PixPack

• Add multiple files at once, or drag an entire folder into the PixPack window.
• Multi-select files in the queue if you only want to process some of them.
• Drag to reorder the queue so files export in the order you want.
• Choose the preset, output format, quality and resize options.
• Press Apply to All Files so the settings apply to the whole batch.
• Review the preview and the per-file compression statistics.
• Export the batch to your chosen output folder.

Queue management

• Add Files to append to the queue
• Clear List to start over
• Per-file checkboxes for multi-select
• Drag to reorder the export order
• Per-file status shown as the batch is processed

Batch limits

PixPack does not publish a fixed maximum batch size in its App Store description. Practical limits depend on the size of the images, the available memory and disk space on your Mac, and the output settings you choose.
