About JPG and ZIP files
JPEG is the standard format for photographs. It compresses by discarding fine detail the eye is unlikely to miss, so files are small but every re-save loses a little more.
A ZIP archive bundles many files into one download. The images inside are stored exactly as they were — JPEGs are already compressed, so zipping them again would save almost nothing. It is a good choice for sending or uploading many photos as a single file.
Limits
Up to 30 files of 25 MB each per batch and images up to 50 megapixels — beyond that browsers run out of memory, so the tool says so instead of producing a broken file. Reading AVIF needs a current browser (Chrome or Edge 85+, Firefox 93+, Safari 16.4+); an older one reports the file as unreadable. HEIC decoding uses libheif in the background and can take a few seconds per photo on a phone. Files that are not images, or are damaged, are rejected with the reason.
