Turn your GIF files into HEIC right in the browser — this tool will shrink each file and hand it back in seconds, with nothing uploaded to any server. GIF is the classic animation format, limited to 256 colours per frame but universally supported for short loops. HEIC is Apple's high-efficiency format, storing iPhone photos at roughly half the size of JPEG with better quality. The conversion keeps your image faithful while switching it into the HEIC container. Free, private, unlimited, and watermark-free.
How to Convert GIF to HEIC
Add your GIF file
Drag and drop, or click to browse. You can convert several at once — they are processed together, right here in your browser.
Convert to HEIC
Pick a quality level if you want to trade a little detail for a smaller file, then press Convert. Encoding is instant for most images.
Download
Save each HEIC file, or grab them all as a ZIP. Nothing was ever uploaded, so nothing needs deleting.
Why convert GIF to HEIC?
The main reason is iPhone photos, where it saves storage dramatically over JPEG. GIF excels at simple animations and small graphics that fit inside 256 colours, but when you need smaller, widely-supported files, HEIC is the better fit. This tool makes that switch instantly, right in your browser.
What happens to quality?
Converting into HEIC re-encodes the image, and because HEIC is lossy you control the trade-off with the quality setting. At high quality the difference is invisible.
A note on file size

Tips & Things to Know
Check the file size after converting
Expect the HEIC file to be noticeably smaller than your GIF. If size matters for your use case, the before-and-after figures shown above tell you exactly what changed, so there are no surprises when you upload or share the result.
Transparency is preserved
Both formats support an alpha channel, so any transparent regions in your GIF stay transparent in the HEIC — nothing is flattened onto a solid background.
Everything stays on your device
This converter runs entirely in your browser using your own processor. Your GIF files are never uploaded, stored, or seen by anyone, which makes it safe for private photos, client work, and confidential documents. When you close the tab, nothing remains.
Tune the quality if you need to
For HEIC you can trade a little detail for a smaller file using the quality slider. At around 90% the difference is invisible to the eye, while the file can be much smaller — useful for web images and email attachments.
