About the HTM file format
HTM File Format (HTM) stores document or productivity content that can be rendered into a shareable image.
The guide and converter lists are generated from the live HEIC.now catalog, so every conversion shown here is an available workflow.
Why HTM files are used
HTM File Format files belong to the documents and text family and use the .htm extension.
The most practical format depends on the software, quality, compatibility and file-size requirements of the destination workflow.
What to know about HTM
File structure
HTM has format-specific rules for storing image, document or media data.
Quality
Conversion can change compression, colour, metadata, resolution or editability.
Compatibility
Support for HTM varies between browsers, operating systems and editing applications.
Original files
Keep the original HTM when future editing or maximum retained information matters.
How HTM conversion works
Converting HTM 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 HTM as an input and converts it to supported outputs.
HTM compatibility and software support
Check that the receiving browser, app or service supports HTM before choosing it for delivery.
A JPG or PNG copy is often useful when broad image compatibility is the priority.
