Detection results are suggestions and can miss content, so always check the preview before exporting. FileSizeFix is free with no limit on how many files you compress. Ads keep it free: a short full-screen ad runs while a job is processing, and the finished files are ready the moment it closes — saving, exporting and sharing are never interrupted by advertising. FileSizeFix Pro is an optional auto-renewing subscription, monthly or yearly, that removes all ads — every tool stays available either way. Prices are shown before purchase and may vary by country. The subscription renews automatically unless canceled and can be managed in your store account settings.
