- Leave the quality at 90 percent, or move the slider down for a smaller file.
- Select Download, or Download all for a ZIP. Names end in
.webp.
Why convert HEIC to WebP
iPhones save photos as HEIC, which many websites and Windows apps cannot open. WebP is a good target when the destination is a website, because browsers display it and the files are typically smaller than a JPG of the same look.
What is kept and what changes
The decoder reads the full HEIC image and rotates it upright. The result is saved as WebP at 90 percent quality by default, so colours and detail stay close to the original. Depth maps, Live Photo video and burst frames are not carried over.
Quality and file size
The quality slider runs from 50 to 100 percent, with 90 percent as the default. A 12 megapixel photo keeps its full pixel size, so only the encoding changes. Large batches are processed a few at a time to keep phones responsive. The first HEIC conversion in a session loads the decoder, which takes a moment, and later files are faster.
When to use it
Choose WebP for photos headed to a website or a CMS that accepts it. If the destination is an email, a printer or a government style upload form, a JPG is safer, so use HEIC to JPG. For lossless output use HEIC to PNG. Everything runs on your device.
Tips
- Convert a whole camera roll batch at once and download a ZIP.
- Lower the quality slider to 80 percent for a smaller file with little visible change.
- Check that the site you upload to accepts WebP, or use HEIC to JPG.
Your files stay on your device. Nothing is uploaded, and there is no sign-up.
