Frequently Asked Questions
What is a HEIC file?
HEIC (High Efficiency Image Container) is the default photo format on iPhones and iPads running iOS 11 or later. It produces files up to 50% smaller than JPG while maintaining the same visual quality, but is not widely supported outside the Apple ecosystem.
Why can't I open HEIC files on my Windows PC?
Windows does not natively support HEIC files without installing a paid extension from the Microsoft Store. The easiest workaround is to convert your HEIC photos to JPG using this tool, which works directly in your browser without installing anything.
Are my photos uploaded to a server?
No. All conversion happens locally in your browser using JavaScript. Your photos never leave your device, making this tool completely private and safe for sensitive images. You can verify this by disconnecting from the internet -- the tool still works.
What output format should I choose?
JPG is the most compatible format and works everywhere -- ideal for sharing via email or social media. PNG is best for images that need transparency or contain sharp text. WebP offers the best compression with good quality and is supported by all modern browsers, making it ideal for websites.
Can I convert multiple files at once?
Yes. You can drop or select multiple HEIC/AVIF files at the same time. They will all be converted automatically. Once complete, use the "Download All as ZIP" button to get them in a single archive.
