If you've ever copied photos from an iPhone to a Windows PC, you've met HEIC - Apple's space-saving format that Windows simply won't preview by default. Instead of installing codecs or paid viewers, you can convert HEIC to JPG right in your browser.
Why iPhones shoot HEIC
Since iOS 11, Apple defaults to HEIC because it saves roughly half the storage of JPG at similar quality. Great for your phone - awkward for everything else: older Windows builds, some printers, and plenty of web forms still expect JPG.
How to convert HEIC to JPG in 3 steps
• Open the HEIC to JPG converter - it runs entirely in your browser.
• Drag your photos in (up to 15 per batch on the free plan, 100 MB each).
• Click Convert and download your JPGs. Files never leave your device.
Why local conversion matters
Most online converters upload your photos to a server, convert there, then send the file back. ChromVel decodes HEIC locally with WebAssembly, so there is no upload step at all.
