Our Principles
Privacy by design. Many of our tools run entirely in your browser, so your files never leave your device. When a tool needs server-side processing, your files are deleted automatically within 30 minutes — and we never inspect, copy or share their contents.
Genuinely free. Every core tool is available without registration, usage limits or watermarks.
Built with care. Each tool is designed and tested by our own team — no auto-generated filler and no compromises on output quality.
Truly global. Filuni is fully localized in 12 languages, including English, Simplified and Traditional Chinese, Japanese, Korean, Spanish, Portuguese, German, French, Russian, Vietnamese and Indonesian.
File Handling & Security
Files that require server-side processing are uploaded over an encrypted HTTPS connection and then automatically and permanently deleted from our servers within 30 minutes. We do not retain, inspect or analyze your file contents.
Prefer to remove your files right away? Simply sign in to your account and delete them manually at any time from your file history.
How we keep Filuni free
Filuni is funded entirely by advertising, which is why every tool is free to use. We display ads from third-party partners, including Google AdSense. Ads are always clearly separated from tool content and never interfere with how your files are processed. For details on how advertising cookies are used, please review our Privacy Policy and Cookie Policy.
