Choose the output format by destination
WebP is a strong default for website images because it usually keeps quality high at a smaller file size.
Practical image guidance
Resize for the place the image will be used
A 1600 pixel wide export is enough for many full-width web layouts, while square profile photos often need exact dimensions such as 512 by 512.
Balance quality, file size, and compatibility
Lower quality settings can shrink photos quickly, but logos, text, and interface screenshots often need PNG to keep edges crisp.
Specific advice for HEIC to PNG
Use JPEG for a smaller photo attachment
PNG can produce a substantially larger file than the source HEIC.
A still photo is not a Live Photo
A Live Photo includes motion data beyond its still image.
Keep your original capture
The PNG is a compatibility copy.
How it works
Choose a HEIC photograph.
Keep PNG selected and set optional dimensions.
Convert and download the PNG still image.
