About HEIC to WebP
WebP keeps iPhone photos small while making them uploadable to websites and CMSs that refuse HEIC. It is a good middle ground when JPG feels too heavy and HEIC is not accepted.
Safari decodes HEIC natively; other browsers load a HEIC decoder the first time, which is slower for large photos.
A quality slider controls the size/quality trade-off (90% by default).
Metadata such as EXIF and GPS location is not copied, because the image is redrawn on a canvas.
HEIC vs WebP
| HEIC | WebP | |
|---|---|---|
| Compression | Lossy, HEVC-based; roughly half the size of a similar JPG | Lossy or lossless; usually 25–35% smaller than JPG |
| Transparency | Possible, but iPhone camera photos are opaque | Full alpha channel |
| Animation | Image sequences exist but are rare | Supported |
| Where it opens | Native on Apple devices; Windows needs an extension; most websites reject uploads | All current browsers; some older apps, CMSs, and print shops reject it |
