Why convert HEIC to WebP?
WebP opens in every browser and is much smaller than JPG, so iPhone photos load fast on websites and blogs without losing quality.
About the formats
- HEIC
- HEIC is the default photo format on iPhones. It keeps high quality at about half the size of JPG, but Windows, Android and many websites cannot open it.
- WebP
- WebP is a modern web format by Google. It is usually 25–35% smaller than JPG at the same quality and supports transparency. All current browsers support it.
Frequently asked questions
Are my images uploaded to a server?
No. Conversion happens entirely in your browser, so your photos never leave your device.
Is there a limit on file size or number of images?
There is no fixed limit. Very large images or big batches depend on your device’s memory, so on a phone it is best to convert a few dozen at a time.
Does converting remove photo metadata?
Yes. The new file contains only the image, so location data and camera details (EXIF) are removed — useful before sharing photos online.
What quality should I choose?
For photos, 75–85% is almost indistinguishable from the original while being much smaller. Use 90% or higher for printing, and 60–70% when file size matters most.
