GIF to HEIC Converter
See why GIF to HEIC conversion isn't currently possible in any mainstream browser, and get pointed to a working alternative.
No browser exposes an HEIC encoder through the canvas API. HEIC uses the patent-encumbered HEVC codec, and even Safari - which can display HEIC - can't produce it from a web page. This tool will confirm that honestly rather than fail silently.

Pro Tips
- •No browser - not even Safari - exposes an HEIC encoder through the canvas API, so this conversion can't be done client-side in any browser
- •HEIC wraps HEVC-compressed image data, and encoding HEVC requires a licensed codec that browsers don't ship for web content
- •If you need a HEIC file, the most reliable path is generating it on an Apple device, where the OS itself provides HEIC encoding
- •This tool never generates a fake or mislabeled file - if conversion isn't possible, it says so clearly
Most Popular
Most users convert to PNG or WebP instead, since those are broadly supported and don't require licensing an HEVC encoder
When to Use This Tool
Use this tool to understand why encoding a GIF to HEIC isn't possible in a browser, and learn about working alternatives.
If you're trying to produce HEIC files for an Apple device workflow, this confirms that step needs to happen on-device instead.
Since HEIC isn't broadly supported outside Apple platforms anyway, converting to PNG or WebP is usually the better choice for sharing.
Learn why PNG or WebP are the practical substitutes when a workflow calls for HEIC output from a browser tool.
How It Works
Read the uploaded GIF file and decode its first frame using the browser's native image support
Draw the decoded frame onto a canvas
Attempt to encode the canvas as HEIC using the browser's native canvas encoder
Detect that no browser supports this and show a clear, honest explanation instead of a broken or mislabeled result
100% Private
Files never leave your device. All processing happens locally in your browser.

Frequently Asked Questions
Why can't browsers encode HEIC?
HEIC images are compressed using HEVC (H.265), a patent-encumbered video codec. No browser - including Safari - exposes an HEVC encoder through the canvas API, so there's no way to produce a genuine HEIC file from web page code.
What should I do instead?
Convert to PNG or WebP instead - both are broadly supported and don't require a licensed video codec to produce. If you specifically need HEIC, generate it on an Apple device, where the operating system handles the encoding natively.
Does Safari support this conversion?
No. Even though Safari can display HEIC images, it doesn't expose an HEIC encoder to web pages through the canvas API, so this limitation applies there too.
Is my file uploaded to a server?
No. The attempted conversion happens locally in your browser. Your file never leaves your device, regardless of whether the conversion succeeds.
Will this tool ever work?
If browsers add native HEIC encoding support in the future, this tool would begin working automatically, since it checks for real browser support rather than assuming it isn't available.
