./instagram-photos-resizer photo1.jpg photo2.jpg

The photos will be uploaded to your Google Photos Library.

Instagram limits the width of the uploaded photos to 1080px. It is recommended to resize the image prior to uploading to avoid heavy compression.

This tool resizes the specified photo(s), splitting them into multiple photos when it detects the width is a multiple of the height.

For example, assume the photo specified is 4000px by 2500px, the tool will split the original photo into 2, both at 1080px by 1350px.
