About ConvertNinja

ConvertNinja is a free tool that turns iPhone HEIC and HEIF photos into universal JPG files. It does one job and does it privately.

Everything happens in your browser

Unlike most online converters, ConvertNinja does not upload your photos anywhere. The conversion runs entirely on your device using an in-browser decoder (heic2any, self-hosted here). Your photos never touch a server, so there is nothing to store, share, or leak.

Free, no account, no watermark

Convert as many photos as you like, at whatever quality you choose. There is no sign-up, no watermark, and no daily limit. Advertising keeps the tool free.

Part of Shinobi Tools

ConvertNinja is one of the Shinobi Tools, a small family of free, single-purpose utilities: background removal, photo restoration, watermark removal, metadata stripping, and more. Each does one thing well, with no upsell.
