HEIC to JPG
HEIC is Apple's default iPhone photo format since iOS 11 — smaller than JPG at the same quality, but poorly supported outside Apple devices, which is why converting to JPG is usually the fix.
You'll typically hit this when uploading an iPhone photo to a website, printing service, or Windows or Android app that shows an error or a blank thumbnail instead of the image.
As a rule of thumb: stick with HEIC when you need it for iphone photo storage, and convert to JPG when photos, where small file size matters most is what you actually need instead. Transparency support carries over either way.
HEIC vs JPG
| HEIC | JPG | |

| Best for | iPhone photo storage | Photos, where small file size matters most |
Frequently asked
- Is my HEIC file uploaded to a server?
- No — the conversion runs entirely in your browser using the Canvas API. Your image never leaves your device.
- What's the maximum file size?
- There's no hard limit, but very large images (over ~50 megapixels) may be slow to process since everything runs on your device rather than a server.
- Can I convert multiple files at once?
- Yes, the converter above accepts multiple files and lets you download them all at once as a zip.
