PDF is the ImageHQ reference page for Portable Document Format. It explains where the format works well, what tradeoffs to expect, and how to choose between PDF and related formats in production image workflows.
Use PDF when the workflow values documents, print-ready layouts, image collections. This is the practical fit that matters before tuning compression or conversion settings.

PDF uses document container compression behavior. That affects file size, editability, transparency, and whether repeated export cycles can visibly change the image.
Convert PDF files when a recipient, browser, archive, or editing tool needs a different balance of compatibility, transparency, file size, or preservation.
PDF is web-ready when browser support and file size match the use case. Compare it with WebP, AVIF, PNG, and JPG before choosing a default.
PDF transparency support: yes. Use PNG, WebP, AVIF, SVG, or PSD when alpha transparency is required.
