Keep a download package manageable.
File dimensions, encoding quality and package count are separate constraints.
Check the destination before packing
Etsy's official digital-listing guide currently allows up to five files per listing and a maximum of 20 MB per file. Other platforms have their own rules. Check the current limit before preparing a collection.

A ZIP is a container, not a quality setting
JPEGs are already compressed. Wrapping them in a ZIP is useful for organization, but often saves little space. PrintPack uses an uncompressed ZIP container, so package size comes from the encoded images plus a small amount of metadata.
Use three separate checks
- Do the exported pixel dimensions meet the intended print size?
- Does each image still look acceptable at the chosen JPEG quality?
- Do both package size and total package count fit the destination?
When a single image is too large
Reduce the short-edge target or choose a lower JPEG quality, then inspect the output. The tool stops if an individual file cannot fit one package; it does not silently lower quality to force a fit.
Every package contains a manifest and branded PDF and printable HTML buyer guide for that product, showing the exact image filename and the ZIP containing it. Only seller-entered sizes that passed the density check are promised in the guide. In Check existing files mode, all imported images belong to one product; non-image ZIP entries are reported as unverified and are not repackaged.
