Most utilities run on your device. Sharing tools explain what reaches our servers and when it expires.
A few things to know
Are OmniKit tools free?
The everyday tool catalog is free to use. Optional Pro access adds multi-file device transfers. Compare Free and Pro for the current price and purchase availability.
Do my files get uploaded to a server?
Most file utilities process input in your browser. Temporary sharing, hosted sites and server-processed downloads use OmniKit servers; some tools contact external providers. Check each tool’s privacy information before sharing sensitive input. Read our privacy policy.
Can I use OmniKit on mobile?
Yes, use a modern mobile browser. Large files and background removal need more device memory; start with smaller files. Downloads, camera access and peer-to-peer transfers depend on browser support.
Do I need an account?
Most browser tools work without signing in. An account is needed for secret sharing and server downloads, and is optional for syncing favorites. Each tool shows its own requirements.
What does OmniKit Plus include?
Plus gives unlimited daily uses of YouTube Watch Room, Temporary Static Site, Bulk File Renamer, Bulk QR Generator and Cross-Device File Drop. Free accounts get 3 uses of each tool per day. Plus also supports up to 20 files per File Drop batch. File-size, batch, room and hosting capacity limits still apply. View plan details; checkout confirms current pricing and availability.
