Image convert

WebP, AVIF, JPEG and PNG with quality control and a before/after size readout. Encoded locally.

WHAT IT WILL NOT DO

Up to 40 megapixels per image and eight files per batch; HEIC and some TIFF cannot be decoded.
Available output formats depend on the browser encoder; AVIF is often read-only.
Converts and resizes only: crop and rotate with I02, inspect EXIF with I03.
