Group photos into a ZIP on Mac

Use an archive to keep a collection together

A ZIP archive bundles files for transfer. The recipient needs to extract it to retrieve the individual images. On a Mac, double-clicking a ZIP in Finder expands its contents. Check that the receiving person or service accepts ZIP attachments before preparing one, particularly when a form explicitly requests individual image files.

A ZIP does not guarantee a large size reduction. JPEG, HEIC and PNG images are already compressed, so an archive may remain close to the combined size of its original files. If your primary requirement is smaller photos, image reduction addresses a different task from keeping files together.

Create and save the archive

PhotoWisp handles up to 500 photos in a batch. Review the selected files before creating the ZIP because the list defines exactly what you will share. Choose a meaningful archive name so the recipient can identify the collection without opening every file.

1. Add the JPEG, PNG or HEIC photos you want to include.
2. Select Group photos together and enter the file name.
3. Run the grouping action. PhotoWisp builds a ZIP locally from the selected originals.
4. Check the reported photo count and archive file size.
5. Choose the destination folder and click Save file.

Understand the contents

The archive contains a Photos folder holding the original files. It does not use copies prepared through compression, conversion, background removal or cropping. Image bytes and embedded metadata remain unchanged. Duplicate file names receive a suffix so that each selected file can be included without replacing another.

This behaviour is useful when the recipient needs source images. It also means you should review what you share: an original may contain embedded information you do not want to distribute. Settings that remove metadata from prepared image copies do not alter originals inside this archive. Keep that distinction in mind when switching between actions.

Check the saved delivery

Open the saved ZIP and inspect several extracted files along with the image count. Adding or removing photos in PhotoWisp invalidates the prepared archive; create it again so its contents match the updated list. Changing only the archive’s name lets you save it again without rebuilding it.

Archive creation happens locally on macOS 14 or later, on Intel and Apple Silicon Macs. The application does not send these photos to a server. Sending the saved file is a separate step, subject to the restrictions of your mail system or chosen transfer service. An archive does not bypass their attachment limits.
