Why choose JPG as the output
JPG is the safest format to hand to someone else. Email programs, print shops, government forms, older phones and office software all accept it, and the files are small enough for most upload limits.
Its limits are worth knowing: there is no transparency, so see-through areas become white, and compression slightly softens sharp edges. For photos, that is rarely visible.
Quality of the result
Pictures are encoded at 92% quality, a setting that keeps photographs looking close to the source while still reducing size. Drop several images at once to download them together in one ZIP.
