HEIC is the default photo format on modern iPhones because it offers high image quality with much smaller file sizes than JPG. Apple adopted HEIC to help users store more photos without sacrificing detail, but many apps, websites, and older computers still cannot open HEIC files. This leads to confusion when trying to upload or share iPhone photos across different platforms. It is frustrating!

The HEIC format is based on the High Efficiency Image File (HEIF) standard, which uses advanced compression to preserve clarity while reducing file size. HEIC photos can include deep color, transparency, and multiple images in a single file, making them more powerful than traditional JPGs. However, the lack of universal support means many users eventually need to convert HEIC files to more compatible formats.

If you have trouble opening a HEIC file on Windows, older macOS versions, or certain websites, converting the file is often the simplest solution. JPG provides maximum compatibility, PNG offers lossless quality, and WebP delivers excellent compression for modern browsers. Converting HEIC files makes them easier to share, upload, edit, and archive.

The easiest way to convert HEIC files is by using an online tool that runs directly in your browser (that’s why we made this HEIC conversion tool!). This avoids installing software and works on any device. Upload your HEIC photo, choose your preferred format, and download the converted file instantly.

Choosing the right format depends on how you plan to use the image. JPG is ideal for everyday sharing, PNG is best for preservation and transparency, and WebP is useful for web design and modern compression. For printing or documents, converting HEIC to PDF is often the most convenient option.

With the growing popularity of HEIC, understanding how the format works—and how to convert it—ensures your photos remain easy to use wherever you share or store them.
