What CompressNow is

CompressNow is a free web service for reducing image file sizes for websites, email, and social networks. It supports batch processing and accepts JPG, JPEG, GIF, and PNG formats; one listed plan also accepts WebP input. Users can choose a compression level, set a maximum width or target size, and select JPG or WebP output. The homepage states a maximum image size of 30 MB. Compression runs in the browser, and the homepage says images do not leave the device. The privacy page says uploaded pictures and generated contents are automatically deleted every three hours. Animated GIFs are converted to still images. JPG does not preserve transparency, so the homepage recommends WebP when transparency matters. The Free plan costs nothing and allows 10 images per operation with a 9 MB per-image limit. The Free online image compressor plan costs nothing, allows 30 images at a time and 30 MB per image, accepts JPG, PNG, GIF, and WebP input, and outputs JPG or WebP. The site uses third-party advertising and session cookies.
