HEIC to WebP
Turn an iPhone photo into a small web-ready WebP.
No server upload
How it works
- Choose a HEIC or HEIF photo.
- Set the WebP quality.
- Convert and download the WebP.
The smallest web-ready copy of an iPhone photo
HEIC (also written HEIF) is what iPhones and iPads save by default. It is compact, but it is an Apple-centric format — plenty of websites, apps, and upload forms cannot read it. If the photo is headed for a web page, WebP is the natural target: it was designed for the web and, like HEIC, uses modern compression to keep files small. This is usually the leanest way to get an iPhone photo onto a site.
Both formats are efficient, so a WebP copy stays close to HEIC in size while working everywhere a browser does. Both are lossy: they save space by dropping detail your eye is least likely to notice. When you pick a file here, the HEIC photo is decoded and re-encoded as WebP entirely inside this browser tab — nothing is uploaded, so it works offline and the photo never leaves your device.
Setting the quality
The quality control decides how much detail to keep. Around the 82% default is a good start for photos — clearly smaller with little visible loss. Nudge it down while watching the result and stop when you can see softening; raise it if you want to hold more detail. Bear in mind the photo is decoded from HEIC before being saved as WebP, so pushing the quality very low compounds the compression. The quality guide walks through where to land.
WebP or JPG?
WebP gives the smaller file and is read by every current browser, so it is the better pick for the web. Choose HEIC to JPG instead when the destination is an older app or form that might not accept WebP yet — JPG opens essentially everywhere. If you need a lossless copy for editing rather than a small web file, use HEIC to PNG. See HEIC explained for background on the format.
| Format | Type | Transparency | Best for |
|---|---|---|---|
| HEIC | Lossy, high efficiency | Yes | Saving space on Apple devices |
| WebP | Lossy or lossless | Yes | Smallest web-ready copy |
| JPG | Lossy | No | Maximum compatibility |
| PNG | Lossless | Yes | Editing copies and transparency |
Already have a JPG or PNG rather than a HEIC? Use JPG to WebP or PNG to WebP instead.
Questions
- Why convert HEIC to WebP?
- WebP keeps files small while being supported by every current browser, so it is a strong choice when an iPhone photo is headed for a website. HEIC itself is not widely readable outside Apple's apps.
- Does WebP keep quality?
- At a matched setting WebP stays visually clean while being small. Raise the quality control toward the top if you want to preserve more detail, or lower it for a smaller file.
- How does the conversion work?
- The HEIC photo is decoded and then re-encoded as WebP, all inside your browser. Because there is a decode step first, keeping the quality reasonably high avoids stacking extra compression on the result.
- Should I use WebP or JPG for my iPhone photo?
- WebP is smaller and ideal for the web. Pick JPG if the destination is an older app or upload form that might not read WebP — JPG opens almost everywhere.
- Is my photo processed on a server?
- No. The HEIC photo is decoded and converted in your browser using the Canvas API, so it never leaves your device and the tool works offline.
- Can I convert several photos at once?
- The tool works on one photo at a time. Convert the first, then load the next — each stays on your device.
