About the PDF file format
Portable Document Format (PDF) 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 PDF files are used
Portable Document Format files belong to the documents and text family and use the .pdf extension.
The most practical format depends on the software, quality, compatibility and file-size requirements of the destination workflow.
What to know about PDF
File structure
PDF has format-specific rules for storing image, document or media data.
Quality
Conversion can change compression, colour, metadata, resolution or editability.
Compatibility
Support for PDF varies between browsers, operating systems and editing applications.
Original files
Keep the original PDF when future editing or maximum retained information matters.
How PDF conversion works
Converting PDF 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 PDF as an input and can also create PDF output.
PDF compatibility and software support
Check that the receiving browser, app or service supports PDF before choosing it for delivery.
A JPG or PNG copy is often useful when broad image compatibility is the priority.
