Convert HEIC to WebP
HEIC is Apple's high efficiency photo format used by iPhones and iPads. Many apps cannot open it directly. Converting to WebP is a size decision: WebP reaches a comparable picture in a smaller file, which is why modern sites serve it. Worth knowing before you start: HEIC is already lossy, and encoding to WebP compresses the image a second time, so the result can only lose detail, never regain it. The conversion runs entirely in your browser: there is no upload, no file size limit and no watermark on the result.
Drop your HEIC files below and download WebP in seconds. Free, unlimited and completely private: the conversion runs inside your browser, so your files never leave your device and are never uploaded to a server.

Why convert HEIC to WebP?
Apple made HEIC the default camera format on iPhone because it stores photos at roughly half the size of JPG. Outside the Apple ecosystem support is poor: Windows needs paid extensions and many websites reject HEIC uploads, making it one of the most converted formats on the web.
Google designed WebP to replace both JPG and PNG on the web, and it typically compresses 25 to 35 percent smaller at similar quality. It handles both lossy and lossless modes and supports transparency. Support is excellent in browsers but still patchy in older desktop software.
HEIC vs WebP at a glance
| HEIC | WebP | |
|---|---|---|
| Full name | High Efficiency Image Container | WebP image |
| Compression | Lossy (HEVC) | Lossy or lossless |
| Transparency | No | Yes |
| Best for | iPhone and iPad photos | Modern websites and apps |
What changes when you convert HEIC to WebP
| What happens | |
|---|---|
| Image quality | Reduced. HEIC is already lossy and WebP compresses again, so this is a second encode. Nothing is recovered, and at low quality settings the losses stack. |
| Transparency | HEIC has no alpha channel, so there is no transparency to lose. |
| EXIF and GPS | Removed. The conversion goes through a pixel buffer, so camera data and location are not carried into the WebP file. |
| Colour profile | Not carried across. The image is handled in sRGB, which is right for the web and wrong for colour-managed print work. |
| Animation | Not applicable. HEIC files here are single images. |
| File size | Smaller in almost every case, which is the reason for the conversion. How much smaller depends on the picture, so no figure is quoted here. |
