About the HEIF file format
High Efficiency Image Format (HEIF) is a digital image format supported by heic.now conversion workflows.
The guide and converter lists are generated from the live HEIC.now catalog, so every conversion shown here is an available workflow.
Why HEIF files are used
High Efficiency Image Format files belong to the raster images family and use the .heif extension.
The most practical format depends on the software, quality, compatibility and file-size requirements of the destination workflow.
What to know about HEIF
File structure
HEIF has format-specific rules for storing image, document or media data.
Quality
Conversion can change compression, colour, metadata, resolution or editability.
Compatibility
Support for HEIF varies between browsers, operating systems and editing applications.
Original files
Keep the original HEIF when future editing or maximum retained information matters.
How HEIF conversion works
Converting HEIF decodes or renders the source and then encodes the result in the selected destination format.
Review the converted file before replacing the source because format-specific features may not transfer.
heic.now accepts HEIF as an input and converts it to supported outputs.
HEIF compatibility and software support
Check that the receiving browser, app or service supports HEIF before choosing it for delivery.
A JPG or PNG copy is often useful when broad image compatibility is the priority.
