HEIC is the format iPhones and iPads use for photos by default. It is efficient, but Windows, many websites, email clients and older apps cannot open it. Converting HEIC to JPG gives you smaller files that every app, website and device accepts.
JPG is the most widely supported photo format, and it compresses photographs very well, so files stay small and open anywhere. JPG is lossy, so it discards fine detail to save space, and sharp text or line art can pick up faint blur. It also has no transparency. This converter reads HEIC in your browser. Safari handles it directly. Other browsers download a small decoder the first time you add a HEIC file, then convert on your device. Large photos can take a moment.
Choose High for a good balance, Max for the least visible loss, or Low when file size matters most. The pixel dimensions follow the original, each file keeps its name with only the extension swapped, and no metadata or watermark is added. Everything runs in your browser, so your images are never uploaded.
Tip: JPG is what most people want from an iPhone photo, because everything opens it. Choose High or Max quality to keep the photo as close to the original as possible.
Slightly. JPG is a lossy format, so some fine detail is discarded. At High quality the difference is hard to see in photographs. Text and sharp line art show it more easily.
Photos have no transparency. If a HEIC file has an alpha channel, PNG and WebP keep it, and JPG fills it with white.
No. The converted image contains only the picture, so location and camera details from the original are not copied into it.
Yes. Add them all, convert once and download a single ZIP. Only the extension changes. A photo named IMG_1234.heic becomes IMG_1234.jpg.
No. The conversion happens in your browser and the files never leave your device.
