You saved an image from Safari and now it won't open in Photos. Or someone sent you a .webp file and your iPhone doesn't know what to do with it. Here are the four easiest ways to open and convert WebP files on iPhone — all free and no sketchy apps required.
Yes — starting with iOS 14, Apple added native WebP support to Safari, Photos, and Files. But there's a catch: while iOS displays WebP images, many apps still don't accept them. If you try to upload a WebP to an app like Instagram, a form, or a document, it may be rejected. And if someone sends you a WebP via WhatsApp or email, saving and re-sharing it often breaks the file. That's when you need to convert.
The quickest method requires zero installation:
This method is privacy-safe because the conversion happens entirely on your device. Your image never leaves your iPhone.
If you're saving images from the web and keep getting WebP files, change how Safari saves images. Unfortunately, iOS doesn't have a built-in setting for this. But you can use a Safari extension like "Save as PNG" or simply screenshot the image instead (volume up + power button) for a quick PNG version. For better quality, use Method 1.
If you convert WebP frequently, set up a one-tap Shortcut:
This takes two minutes to set up once and saves you time every time after.
If you just need to view the WebP, open the Files app and navigate to the file. iOS's Quick Look viewer handles WebP natively. From Files, you can also use the Share sheet to send it to a converter or shortcut.
