HEIC (High Efficiency Image Container) is what every iPhone photo is saved as by default — files are about half the size of equivalent JPEGs at the same quality. Beautiful in iCloud, awkward everywhere else: Windows Mail, most Slack desktop versions, government upload portals, and many printer drivers refuse to display HEIC. Wrapping the photo in a PDF works around all of that — every PDF reader on every operating system shows it.
PDFly decodes the HEIC in your browser using libheif (the same engine Apple uses), then embeds the image into a PDF page sized to match. The original HEIC and the resulting PDF never leave your device.
