How to use Batch Compress Images
  1. Choose the supported source images from your device.
  2. Adjust the controls and review the original preview.
  3. Select Process locally, review the result and download the output.
What to expect
Compress JPEG or WebP image copies locally and receive a ZIP with a per-file results manifest. Compress multiple photos sequentially and compare actual output byte sizes.
Limitations and image privacy
JPEG/WebP use adjustable quality. PNG is lossless. Results can be larger; animated inputs export one still frame.
Each file is capped at 20 MB and 30 million decoded pixels. Multiple files are processed sequentially to limit CPU and memory demands. Files are processed locally; nothing is transmitted to the image-processing server. Generated copies can differ from the original and original files remain on your device.
