What happens to your image going from HEIC to WebP
- WebP is a lossy format. The Quality slider begins at 90%, which is indistinguishable from the original for almost any photo; slide it down for a smaller file and the preview shows the new size before you save.
- Make sure the place you're uploading to takes WebP – most sites and browsers do, though some older apps and forms don't.
- Your photos keep their full resolution, and the WebP opens on Windows, Android and any website.
HEIC vs WebP in brief
- HEIC is the photo format Apple uses by default on iPhone and iPad. It packs a picture into about half the space a JPG would need, yet plenty of Windows computers, web forms, websites and older apps refuse to open it.
- WebP is an image format Google designed to make websites load faster. It handles lossy and lossless compression, transparency and animation, and typically comes out 25–35% smaller than a matching JPG, although some editors, older programs and upload forms still won't take it.
iPhone tips
- To shoot JPGs from now on, go to Settings › Camera › Formats and pick Most Compatible (photos take roughly twice the space).
- Picking from Photo Library can make iOS pass along a JPG it has already converted. If you need the untouched original, save it to Files first and use Choose File.
- You don't need anything from the App Store – the tool works inside Safari and the file stays on your iPhone.

Questions & answers
Does changing HEIC to WebP lower the quality?
At the 90% default you won't be able to tell. WebP is lossy, so very low settings can bring blur or blocky edges.
Can I do a whole batch of HEIC files?
Yes. Add as many as you want; each is converted separately, and Download all bundles them into a single ZIP.
Do my photos get sent anywhere?
No. Your browser does the conversion with your device's own processor, so your photos stay with you. Once the page has loaded you could even switch off your internet connection.
Where do I find the converted file on my iPhone?
Tap Download. Safari puts the file in Files › Downloads (the download arrow in the address bar takes you there). To get an image into Photos, open it in Files, tap Share, then Save Image.
