ZIP Image Resizer

The ZIP Image Resizer processes a ZIP archive containing images and outputs a new ZIP with resized assets. It respects original folder structure and only modifies image files that meet the supported formats, leaving other files untouched. Users include web developers, game asset teams, marketers, and content operations who need consistent batch resizing before deployment.
Conceptually, the tool unpacks the archive, inspects each image to determine a scale factor based on the configured maximum width and height, and applies a resize operation that preserves aspect ratio. Depending on the mode, it can fit images within bounds or fill the bounding box. After processing, images are re-encoded with the chosen quality setting and re-zipped in the same relative paths.
The value proposition is automation, reproducibility, and time savings. It reduces manual edits, ensures uniform output across large asset sets, and minimizes bandwidth by producing smaller ZIPs. It supports different formats, preserves metadata optionally, and can be integrated into pipelines for content pipelines or release management.
Core features include: batch resize, folder-structure preservation, non-image pass-through, quality control, optional format conversion, and detailed processing logs. Typical use cases include preparing marketing banners in bulk, game studios packaging assets for distribution, and agencies delivering web-ready image bundles to clients.
