Why convert HEIC to WebP?
HEIC is excellent for storing photos on Apple devices, but it has some limitations:
- Does not open on Windows, Android or most websites
- Rejected by job and exam portals
- Patent-encumbered codec
Converting to WebP gives you:
- Much smaller than JPG and PNG
- Transparency and animation
- Supported by all modern browsers

What are HEIC and WebP files?
HEIC (.heic, .heif)
HEIC is the default photo format on iPhones. It stores high-quality photos at about half the size of JPG, but Windows PCs, Android phones and most websites cannot open HEIC files directly — so they usually need converting.
WebP (.webp)
WebP is a modern image format by Google that makes files 25–35% smaller than JPG or PNG at similar quality. It supports transparency and animation, and is used heavily by websites — which is why images saved from the web often end up as .webp.
Tips for the best WebP results
- On iPhone you can stop HEIC permanently: Settings → Camera → Formats → Most Compatible. Existing photos still need converting.
- A quality of 85–92% gives excellent results at a fraction of the size. Use the Image KB Converter if a form requires a specific file size.
- Bookmark this page or install the app to convert HEIC files offline next time.
Private by design: how this converter works
Unlike typical online converters that upload your file to a remote server, this HEIC to WebP converter processes everything on your own device using the HTML5 Canvas API and native image decoders built into your browser. Your file is read into browser memory, converted, and offered back as a download — it is never sent to us.
- No upload wait — conversion starts instantly, even on slow mobile data.
- Private — safe for NID copies, certificates, bank statements and personal photos.
- No limits — no daily quota, no queue and no watermark.
- Offline-ready — once loaded, many tools keep working without internet.
