Privacy Policy

Every converter here is free, full size, no account. Photos convert in your browser and never leave it. Video and e-books do need our server — those we delete right after.

Last updated: 18 July 2026

ConvertNinja is built to need almost none of your data. This policy explains exactly what happens.

Your photos never leave your device

• The HEIC to JPG conversion runs entirely in your browser with JavaScript.
• Your photos are not uploaded to any server. We cannot see them, store them, or use them for anything.
• The converted JPGs are created on your device and saved by you directly.
• There is no account, so nothing you convert is ever tied to an identity.

Visitor statistics

We count page views to understand how many people use the tool. This count is stored on our server as anonymous, aggregated numbers. We do not store your raw IP address; it is only used momentarily to filter out bots and is never written to disk in full.

Email list

You can leave your email address to get a free 12-hour Pro pass, and another one every month — what it unlocks changes from month to month. That is the only reason we ask for it. The tools work without it: nothing here needs an account, and nothing is hidden behind giving us your address.

We store the address, when you signed up, which site you signed up on, the IP address you used, and the exact sentence that was shown next to the button when you asked for the pass. That last part is the proof that you asked for this, which is what the law expects us to keep. We only ever email an address after you click the confirmation link in the first email, so nobody can put someone else on the list.

The emails themselves are delivered by Resend (Resend, Inc.), which sees the address in order to deliver the message and nothing else. We keep your address until you unsubscribe.

Every email has an unsubscribe link that works in one click, without logging in. Use it and your address is deleted — all that stays behind is a one-way hash, so we can show that we honoured it. We never sell, rent or share the list, and we don't use it to follow you around the web.

Advertising

When ads are shown here, third-party vendors — including Google — use cookies to serve ads based on your prior visits to this website or other websites. Google’s use of advertising cookies enables it and its partners to serve ads based on those visits. You can opt out of personalised advertising in Google’s Ads Settings, and opt out of some other vendors’ advertising cookies at www.aboutads.info.

This site shows ads through Google AdSense to keep the tool free. Google may use cookies and similar technology to serve and measure ads. You can review this through Google's ad settings. We do not sell any data.

Cookies

ConvertNinja itself sets no tracking cookies. Your dark-mode preference is stored locally in your browser only. Third-party services such as AdSense may set their own cookies as described above.
