No subscription that lets you convert more images, really fast, could put up to 1250 images at the same time and took less than 4 minutes to convert, ads aren't that normal to come by, overall great app, based developers for making one of the best convert apps out there entirely for free
The first file converted from *.WEBP to *.JPEG with no problems. A long video advertisement will play after every conversion. Batch conversion costs extra . I only tested this on small files. Files seem to convert safely while offline.
