Common use cases
People convert HEIC to PDF when their photo's container format is blocking the next step in a workflow that already accepts PDF. iPhones default to HEIC for the storage and compression gains, but a large slice of the receiving systems people actually have to deal with — HMRC self-assessment, US tax portals, NHS appointment uploads, council benefit applications, university coursework drop-boxes, expense management tools, payroll evidence portals, and standard email clients running on Windows 10 — silently fail or mis-render HEIC. The cheapest fix is wrapping the photo in a PDF, because PDF is the lowest-common-denominator document format on every platform from a 2014 Windows laptop to a kiosk PC at a council reception. The same tool also helps when several HEICs need to land at the destination as a single document — a series of receipts as one expense claim, a set of meter readings as one utility submission, a four-page handwritten signed form scanned in pieces. Doing this once in the browser (no upload, no signup, no watermark) re-encodes each photo as high-quality JPEG (the same export pipeline iOS uses when it shares a HEIC to non-Apple devices) and embeds it into the PDF — and avoids handing photos to a third-party server purely to swap a container.
