SwapHEIC is a browser-based image converter. Drop a file, get the converted file — nothing uploaded, no account, no size limit, no watermark. It started as a HEIC → JPG tool (the format iPhones uses), but it’s grown to cover 10 common routes across HEIC, WEBP, PNG, JPG, and GIF — the conversions people actually need before emailing, uploading, or editing photos. All conversion runs client-side in your browser. Your images never touch a server. Works on any device, OS, offline after first load.
