Both convert HEIC photos to JPG. Only one keeps your photos off the internet. Here is the full breakdown so you can decide for yourself.
PixHeic: 100% Local — Files Never Leave Your Browser
Quick verdict
If privacy matters — medical photos, ID documents, personal images — use PixHeic. Conversion never touches a server, there is no file limit, and it works offline. HEICtoJPG.com is a capable tool but it is server-based: your photos travel to and from a remote machine you do not control, and free use is capped. For occasional personal photos on a trusted connection it is fine. For anything sensitive, or for large batches, PixHeic is the clear choice.

When a converter is server-based, your photo travels across the internet to a machine owned by someone else, gets decoded and re-encoded there, and is then sent back to you. At each step, that third party could — in theory — store, log, or process the image. For holiday snapshots this may feel academic. For photos of children, medical records, ID documents, or anything you would not post publicly, it is a meaningful risk.
PixHeic loads a WebAssembly build of libheif — the same open-source decoder Apple's own tools use — and runs it entirely inside your browser tab. Open DevTools, go to the Network panel, convert a photo, and you will see no outbound image traffic. There is no upload endpoint in the code.
Because the conversion runs locally, speed scales with your CPU — not your internet connection or a shared server queue. Drop 40 photos from a weekend trip and the first JPG is ready while HEICtoJPG.com is still uploading file three.
There is no server to meter, so there is no limit. Convert ten photos or a thousand — the same tool, the same tab, no sign-up and no paid upgrade to unlock larger batches. Your device's RAM is the only ceiling, and a modern laptop handles several hundred iPhone photos without breaking a sweat.
Being direct: HEICtoJPG.com is a well-known tool that works for many people. Here are the specific situations where its server-based approach is less of a concern.
You have one or two photos that are not sensitive — a product shot, a meme, a screenshot from your phone.
You are on a very old browser (pre-2019) that does not support WebAssembly. PixHeic requires a modern browser; HEICtoJPG.com works on anything.
You want EXIF metadata preserved in the output JPG. PixHeic strips all metadata by design; HEICtoJPG.com may carry it through.
Outside those cases — especially for photos of people, medical images, ID documents, or any batch larger than a handful of files — PixHeic is the more private, faster, and less restrictive choice.
Drop your HEIC files into PixHeic. Conversion runs entirely in your browser — no account, no file limit, no server.
