Frequently asked questions
Should I choose WebP or JPG for my iPhone photos?
Choose WebP for websites and apps you control, where smaller files help speed. Choose JPG when the photo has to work everywhere, including email attachments, print shops and older software that may not read WebP.
Will the WebP be smaller than the HEIC?
Usually similar, and sometimes a bit larger. HEIC is already very efficient. The savings show up against a JPG of the same photo, which is typically a quarter to a third bigger than the WebP.
Can an iPhone open the WebP file?
Yes. Safari and other apps on iOS 14 and later display WebP images, and macOS Big Sur and later does as well. Older versions may not.
Are my HEIC files uploaded anywhere?
No. The conversion runs in your browser using WebAssembly, so your HEIC files stay on your device. There is no signup, no watermark and no cost, and you can convert a whole batch and download it as a zip.
About HEIC to WebP
WebP suits photos that are headed for a website, a blog or an online store. Most browsers cannot display HEIC outside Safari, so a photo straight from an iPhone is unusable on a page, and a JPG works but is bigger than it needs to be. WebP is the middle path: every current browser shows it, and it generally comes out around a quarter to a third smaller than the equivalent JPG, which helps pages load faster.

Both formats are lossy, so the photo is compressed twice. At normal viewing size the difference is rarely visible, but avoid repeating the process on the same picture. WebP files from a photo tend to be in the same range as the HEIC, sometimes a little larger, and noticeably smaller than a JPG. Metadata such as GPS location is dropped, and the photo's orientation is applied so it stays upright. Some older editors and upload forms still refuse WebP, so check the destination first.
HEIC is lossy, compressed with HEVC (H.265); WebP is either lossy or lossless, depending on how the file was saved. Both formats can store transparency, so transparent areas in the HEIC file stay transparent. For scale, a 12-megapixel photo is typically 1.5 to 3 MB as HEIC and 1.5 to 3.5 MB as WebP. Compatibility: Every current browser displays it. Some older desktop software, email clients and upload forms still reject it.
