About Batch Image Preparation
How it works
Each successful result is checked against actual bytes. KB means 1,000 bytes. Images retain their proportions and are never enlarged. Allow further shrinking if meeting the byte limit is more important than keeping dimensions.
Supported files and practical limits
Use up to 20 files, 20 MB and 25 megapixels each, 100 MB combined. Outputs are JPG or WebP still images without original metadata. JPG replaces transparency with white. A failed file does not discard successful results.
