Turn iPhone HEIC photos into universally compatible JPEGs that open anywhere.
HEIC is Apple's file extension for images encoded under the High Efficiency Image File Format (HEIF) standard, using HEVC (H.265) compression. Apple made it the default photo format on iPhones starting with iOS 11, since it stores images at roughly half the file size of an equivalent-quality JPEG. As a container format, a single HEIC file can also bundle image bursts, depth data, or Live Photo sequences together. The main friction point is compatibility: older software, most Windows PCs, and many web platforms still can't open HEIC natively, which is the main reason people convert it to JPG.
JPG is the most common file extension for images compressed with the JPEG standard, published in 1992. It applies lossy compression based on the discrete cosine transform, splitting images into small blocks and discarding visually insignificant detail to shrink file size. The compression level is adjustable: higher quality keeps more detail at a larger size, while lower quality trades visible artifacts for a much smaller file. JPG supports 24-bit true color and embeds Exif metadata such as camera model and capture date. Its biggest strength is universal compatibility — it is the native output of virtually every camera and phone, and opens in every browser, viewer, and operating system without exception.
Most Windows PCs and older devices cannot open HEIC files. Converting to JPG removes that friction entirely.
Apple uses HEIC because it achieves the same photo quality at half the file size.
Yes, this tool is completely free with no registration, no watermark, and no conversion limit.
No, the conversion happens locally in your browser using JavaScript. Your files are never uploaded to any external server.
There's no fixed limit enforced by the tool since everything runs in your browser rather than on a server.
For most everyday uses, the visual difference is negligible.
