Limitations and image privacy
JPG flattens alpha; animated inputs become a still frame. WebP encoding depends on the browser.
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.
