About FixHEIC

HEIC tools that run in your browser, not on a server.

Why this site exists

Apple's HEIC format makes iPhones store more photos in less space — great for Apple users. Painful for everyone else. Send a HEIC to a Windows friend, a Slack channel, your payroll portal, your school's submission form, and you'll get back a polite "this file type isn't supported."

The standard answer is to upload your photo to a sketchy converter site that wants your email, shows you ten popups, and may or may not keep a copy. We thought there should be a cleaner option.

The fix

Modern browsers can decode HEIC themselves. We bundle libheif compiled to WebAssembly and run it in the tab. Your photo never leaves your machine. No upload, no signup, no watermark, no email.

How to verify nothing uploads

Open browser DevTools, go to the Network tab, run a conversion. You'll see the converter library load once. You won't see your file being uploaded anywhere. Even simpler: load the page, kill your Wi-Fi, then run a conversion. It still works.

What we use

How this site stays free

Display ads from Google AdSense. There are no servers processing your photos, so our costs are basically zero — domain registration and Cloudflare's free static-site hosting.

Limitations

Your phone or computer does the work. Phones generally handle iPhone-sized HEICs (a few MB) fine. Laptops can do 100+ MB HEICs without trouble. If you're trying to convert several gigabytes of photos at once, the browser will run out of memory eventually.
