WebP: the web’s format, not your camera roll’s
WebP is everywhere online because it makes pages load faster. That’s great for websites and a bit awkward for everyone else. Right-click “Save image” on a recipe, a product photo or an artwork and you’ll often get a .webp file, which some photo apps and older editors don’t handle well.
If you collect images for mood boards, references or wallpapers on Apple devices, converting them to HEIC puts them in the same format as the rest of your library.
WebP to HEIC or WebP to JPG?
| Your goal | Better choice |
|---|---|
| Keep images in Apple Photos | HEIC (this page) |
| Share with anyone, any device | JPG |
| Keep transparency on Apple devices | HEIC |
| Upload to forms or print | JPG |
We don’t have a WebP to JPG page yet, but if you need maximum compatibility, JPG is the safe destination. For anything staying in your Apple world, HEIC is tidy and compact.
Set expectations on size and quality
Web images have usually been squeezed hard already. Re-encoding them to HEIC won’t sharpen them, and it won’t always make them smaller. What it does is give you a file that Photos, Preview and the rest of Apple’s apps treat like any other picture from your phone. For photos you’ve taken yourself as JPGs, JPG to HEIC gives bigger savings.
There’s also no metadata to worry about: nothing is written to HEIC output, so any tracking details or author tags in the downloaded file are left behind.
Saving straight into Photos on iPhone
On iPhone and iPad, open this page in Safari and pick your WebP files from the Files app, usually in Downloads. Once the HEIC files are ready, tap Save and choose to add them to Photos from the Share sheet. Very large images may be scaled down a little, because Safari limits how big an image the browser can work with.
No server in the loop
The HEVC encoder (kvazaar) is compiled to WebAssembly and runs in your browser tab, so your downloads stay where they are: on your device. It’s slower than converting in the other direction, but you can install the app and run it offline. Want to know more about the format you’re converting to? See what HEIC is.
