HEIC to PNG
This lesson is part of Web Developer Tools · All levels
Summary
PNG stores the decoding results of HEIC photos in a lossless container, so there is no additional compression when the file is written. However, the details that were lost when HEICs were created are irreversible, and PNG size can actually be multiplied many times. This format is useful when you need to edit further, maintain transparency, or give a file to an application that only accepts PNG. For ordinary photo distribution, JPG or WebP is usually more space-efficient.
Key points
- PNG lossless, but can't recover details that are already lost in HEIC
- The PNG size of the resulting photo conversion is usually much larger than HEIC or JPG
- PNG is useful for editing streams and applications that require this format
- Alpha channels are fully supported if the source is transparent.
- Avoid PNG for web photos because it slows down loading
