Frequently asked questions about Image tools

Are these Image tools free?

Yes — every Image tool on OmniTools is 100% free with no watermarks, no limits and no account required.

Do I need to sign up or install anything?

No. All 11 Image tools run in your browser — nothing to download, install or register for.

Are my files and data private?

Most tools process your data entirely on-device in your browser, so nothing is uploaded. Where a file must be processed on the server, it is sent over HTTPS and deleted right after.
