Open your iPhone HEIC photos. Anywhere.
Your iPhone saves photos as HEIC. Windows can't open them by default. Slack rejects them. Your work portal says "unsupported file." FixHEIC turns them into JPG, PNG, or PDF — right in your browser. No upload, no signup, no watermark.

Why HEIC is a problem
Apple-only by default
HEIC was designed by Apple. Windows ships without HEIC support. Most non-Apple apps refuse to open it.
Smaller files — but only if you can open them
HEIC is half the size of JPG at the same quality. Great for storage. Terrible when you need to email one to someone on Windows.
The Microsoft Store codec doesn't fix it
Even with the paid HEVC codec from Microsoft, most Windows apps still won't accept HEIC. Converting to JPG is the only reliable fix.
Slack, work portals, payroll, school
Almost every business app refuses HEIC. Convert first, then upload.
Questions people actually ask
Why won't my HEIC file open on Windows?
Windows ships without HEIC support. You can install a paid HEVC codec from the Microsoft Store, but most Windows apps still won't read HEIC even after that. Easier to convert to JPG.
Are my HEIC photos uploaded?
No. The conversion runs in your browser via libheif compiled to WebAssembly. Open DevTools, watch the Network tab, run a conversion — nothing's uploaded. Or kill Wi-Fi after the page loads; it still works.
How do I get HEICs off my iPhone?
Easiest: connect your iPhone to your computer with a cable, open Photos / File Explorer, drag the HEICs out. Or AirDrop to a Mac. Or email yourself the photos (but Apple Mail sometimes auto-converts to JPG, which defeats the purpose).
What's the difference between HEIC and HEIF?
Same format, different file extensions. Some Android phones and other devices use .heif; iPhones use .heic. Both work here.
Can I batch convert?
Yes. Drop as many HEICs as you want. You'll get a ZIP back.
What's the largest HEIC I can convert?
Limited by your device's memory. A modern laptop handles 100+ MB HEICs without trouble. Phones struggle past 30–50 MB per file.
Why not just use Apple's Photos app to export as JPG?
You can, if you have a Mac. If you're on Windows, Linux, ChromeOS, or want to convert hundreds at once without opening Photos — this is faster.
