On your iPhone
Four taps, done
Choose your WebP files
Tap the drop zone and pick files from Files, Photos, or wherever the WebP is saved — several at once works fine.
Convert
PNG is the default output — lossless and transparency-safe. Switch to JPG with the quality slider when you need smaller files.
Save or share
Download each file, or grab the whole batch as a ZIP. Tap the download in Safari's downloads to move it to Files or share it to Photos.

Questions
iPhone FAQ
Does the iPhone support WebP files?
Modern versions of Safari on iPhone and iPad decode WebP images — photos and downloads open fine. The limitation is exporting or uploading PNG/JPG versions, which is exactly what this converter handles.
Where do the converted files go on iPhone?
Downloads land in Safari's Downloads folder or the Files app, depending on your browser settings. The ZIP download keeps an entire batch in one place; individual PNGs can be shared to Photos or any app from the share sheet.
Why use a website instead of an app?
No installation, no permissions, no account, and your images are processed on your own device — nothing is uploaded to a conversion server.
Can I resize photos while converting on iPhone?
Yes. Set an optional output width and height before converting, and keep the ratio lock on to avoid stretching.
