Privacy & Security
Most online converters ask you to upload your files to their servers. HEIC Toolkit does not. Conversion happens entirely inside your browser, which means your photos are never exposed to the network in the first place. Security here is not a feature bolted on top — it is the way the tool is built.
Files never leave your device
Every conversion runs locally in your browser using JavaScript. Your HEIC files are read by the browser’s local file API and processed on your own machine — they are never uploaded to a server.
No servers to breach
Because we do not receive, store, or transmit your files, there is no server-side copy of your data that could be leaked, intercepted, or subpoenaed. The most secure data is data that never travels.
No account, no tracking of content
You do not sign up, log in, or hand over any personal information to convert a file. We never inspect, fingerprint, or retain the contents of the images you process.
Served over HTTPS
The site itself is delivered exclusively over an encrypted TLS connection, so the application code your browser runs cannot be tampered with in transit.
How client-side conversion protects you
When you drop a HEIC file onto the page, the browser loads the conversion libraries on demand and decodes the image using your device’s own processor. The resulting JPG, PNG, or PDF is assembled in memory and handed straight back to you as a download. At no point is the file — or any part of it — transmitted to us or to a third party. There is no upload step to intercept, no temporary server file to recover, and no log of what you converted.
Data in transit and at rest
The website and all of its assets are served over HTTPS using modern TLS encryption, protecting the integrity of the code your browser downloads. Your files are processed in volatile browser memory and are discarded the moment you close or refresh the tab. We operate no database of user files, because we never receive any.
Analytics and cookies
We use a privacy-respecting analytics tool to understand aggregate, anonymous usage — such as which pages are visited — so we can improve the site. This never includes the contents of your files. For the full detail of what is stored in your browser, see our Cookies Policy and Privacy Policy.
Responsible disclosure
We take the security of this site seriously. If you believe you have found a vulnerability or have a security concern, please let us know so we can investigate and address it. Reach us at [email protected] . We appreciate reports made in good faith and will respond as quickly as we can.
